One-component spray polyurethane foam (SPF) is dispensed as a frothy liquid which expands and moisture-cures into a solid foam insulation and sealant. One-component foam is available in convenient aerosol cans and portable cylinders.

One-component foam is used to fill and seal small cracks and voids such as around door and window frames, sill plates, electrical devices where air leakage and energy loss can occur. Formulations are available for general use and specific applications such as sealing windows and doors, fire blocking, and construction adhesive. All Touch ‘n Seal one component polyurethane foam products are rated ASTM E-84 Class I (A) fire resistant. Consult with local building codes for guidance on acceptable uses.

What is a Two Component Spray Polyurethane Foam Sealant?

Touch ‘n Seal two-component low-pressure spray polyurethane Foam Kits combine A-component and B-component to produce a frothy mixture that expands rapidly and chemically-cures to form solid foam. A-component (“Iso”, “MDI”) and B-component (“Polyol”) are delivered from portable cylinders through hoses to a spray applicator gun. The applicator mixes the components and creates the spray pattern to control the application of foam to vertical or horizontal surfaces.

Touch ‘n Seal Spray Foam Kits are an excellent choice for insulating and air sealing small to mid-sized residential, commercial, industrial, and agricultural construction projects. Touch ‘n Seal spray foam insulation is especially effective in air-sealing and weatherizing older homes that have many energy wasting cracks, gaps and penetrations that allow air to leak in and out of the house. It can be used to air seal behind fiberglass, cellulose and other permeable insulation products (“flash and batt”.) Touch ‘n Seal two-component systems are an efficient way to apply spray foam to seal and insulate critical places in the building envelope such as rim joists and around large penetrations. Foam Kits are a convenient way to make small repairs of existing spray foam installations, including wall insulation and roofing systems. Refillable cylinders are available a cost efficient means of using Touch ‘n Seal two-component systems for in-plant applications.

Safety, Storage and Handling Guidelines

What are some general guidelines for using and storing Touch 'n Seal foams?

Refer to product SDS and Safe Use, Storage, and Handling for Low-Pressure Spray Foam Products for detailed safety guidance prior to use. More information regarding safe use and handling of Low-Pressure Spray Polyurethane Foams and Sealants is available at www.spraypolyurethane.org.
Use products only in a well-ventilated area. Avoid breathing vapors.
For two-component spray foams, wear an organic vapor cartridge respirator.
Wear personal protective equipment (PPE): safety glasses or goggles, chemical resistant gloves and clothing to protect from skin exposure. Avoid skin contact.
Do not allow others without the proper PPE into the immediate vicinity of the spray application.
Ventilate area during application and for at least one hour after two-component foam is applied.
Keep out of reach of children.
Store products in a well-ventilated dry location between 60° - 90°F (16°-32°C).
Do not expose products to open flames or temperatures above 120°F (49°C).
Do not expose finished foam product to open flames.
Follow recommended pressure relief instructions for empty containers prior to disposal.

How do I remove wet foam from surfaces?
Use Touch ‘n Seal Poly-Clean or acetone and a clean cloth or paper towel. Do Not Apply Poly-Clean or acetone to any finished surface. Always test a small inconspicuous area to ensure Poly-Clean or acetone will not damage the surface. DO NOT USE SOLVENTS TO REMOVE FOAM FROM SKIN.

How do I remove wet or cured foam from my hands, skin or hair?
Polyurethane foam has extraordinary adhesive strength and is very difficult to remove. It is important to wear chemical resistant gloves and protective clothing to avoid skin contact during application. If foam does come in contact with skin, immediately wipe off as much of the liquid as possible and wash well with and soap and water. Generously apply moisturizing lotion. Do not use solvent to try to remove the foam. Residual foam on the skin will gradually wear off over time. If a rash or persistent irritation develops, consult a physician.

Just as with skin exposure, foam cannot be completely removed from hair. It may be necessary to cut off foam encrusted hair. If a rash or persistent irritation of the scalp develops, consult a physician

How should unopened foam containers be stored?

Store Touch ‘n Foam one- and two-component foam systems in a dry, well-ventilated area between 60° – 90° F (16° - 32°C.)

Storage above 120° F (49°C) may result in chemical leakage due to excessive pressures. Do not store near open flames or other sources of heat or ignition. Pressurized cylinders have a safety rupture disk which will relieve excessive pressure; however, chemical leakage will occur when the disk ruptures.
Storage below 60° F (16° C) may result in crystallization of the liquid components and affect the quality of the finished product.

Always check the product label for application and storage temperature ranges.

Keep out of reach of children.

What is the cure time for Touch ‘n Seal foam?

Cure time is dependent upon temperature, humidity and formulation. Please check your product label or go to the product page of this website and view the product data sheet to obtain an accurate cure time. Two-component foams are tack-free and cure much more quickly than one-component foams.

Will polyurethane foam support the growth of fungus or mold?

No. Mold and other micro-organisms require a food source, moisture and oxygen to live and grow. Since polyurethane foam is not a food source for mold and fungus, it does not support growth. However, materials adjacent to or in contact with the foam, such as wood, cellulose insulation, dry wall paper, dust and dirt may are food sources and may support growth.

Is foam a barrier to insects and rodents?

Convenience Product’s polyurethane foams do not contain chemical rodent deterrents or rodenticides.

Use of expanding polyurethane foam has been found to be an easy, means to help prevent insects rodents from entering structures through voids, cracks and crevices.
Carefully select the appropriate foam based upon construction types and opening sizes for the area being filled. Follow all product instructions and safety guidelines.

Completely fill holes around the structure, such as in the siding close to the foundation, around cables and pipes that penetrate the structure and all openings in areas with evidence of rodents, such as gnawed items and rodent droppings. Do not overlook small holes. Some rodents, such as house mice, can squeeze through holes that are as small as ¼-inch across, according to information from the University of California's Integrated Pest Management Program.

While mice and rats can chew through polyurethane foam, this barrier will generally block mice from entering the area. Rats will chew through almost anything if motivated.

Is foam water resistant?

Closed cell polyurethane foam resists immediate water penetration. However, foam may absorb water that is in direct contact for extended periods of time.

Do Touch ‘n Seal polyurethane foams reduce sound and noise transmission?

Spray foam can be used to reduce the transmission of sound by sealing gaps and cracks with one-component spray foam. Two-component spray foam can be used to fill larger spaces, such as between wall studs or floor and ceiling joists. Several Touch ‘n Seal® two-component spray foams have been tested for sound control characteristics. The below represent the most common ASTM test procedures referenced within our industry.

ASTM E90 - 09 Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions and Elements, commonly referred to as STC or Sound Transmission Class. This standard evaluates the amount of sound loss thru a specific wall test assembly and roughly equals the decibel reduction in noise a partition can provide.
ASTM C423 - 09a Standard Test Method for Sound Absorption and Sound Absorption Coefficients by the Reverberation Room Method, commonly referred to as NRC or Noise Reduction Coefficient. This standard evaluates the amount of sound that a specific test assembly surface can absorb. An NRC of “0” means perfect reflection, while an NRC of “1” means perfect sound absorption.

Refer to the individual spray foam Technical Data Sheets for sound control ratings.

Is Touch ‘n Seal foam suitable for exterior / outside applications?

Polyurethane foam can discolor and degrade in sunlight. Touch ‘n Seal foams can be used for outside applications if covered with an exterior grade coating.

Touch 'n Seal Black Foam contains additives to inhibit degradation from sunlight and can be used without a coating.

Can I apply Touch n’ Seal foam around hot water pipes?

Touch ‘n Seal 1.75, 2.0 and 3.0 pcf foams may be applied to hot water pipes. Do not apply to steam or other pipes that may exceed 250°F (121°C). Touch ‘n Seal 1.0 pcf foam should not be applied to any surface that might exceed 200°F (93°C).

All Touch ‘n Seal one-component foam sealant formulations have less than 250 grams / liter VOC’s.

All Touch ‘n Seal 2-component polyurethane spray foams are low VOC.

The VOC content of Touch ‘n Seal products is given in section 9 of the Safety Data Sheet (SDS.)

How does Touch ‘n Seal foam save energy?

Touch ‘n Seal polyurethane foams provide a continuous insulating air barrier that helps stabilize and maintain inside temperatures by resisting heat movement and preventing moisture infiltration through air leakage.

How much expansion should I expect with Touch ‘n Seal two-component foam?
Touch ‘n Seal two-component foam, when applied according to directions, will expand varying amounts depending upon the foam’s designed density. The lower the density, more expansion will occur. 1.75 pcf SPF will expand approximately 6 – 8 times the volume of the dispensed froth. 1.0 pcf SPF will expand approximately 10 – 12 times the dispensed froth.

Can I stop spraying and re-start my Touch ‘n Seal product later?

Yes. Be sure to follow the instructions below for your specific foam product.
All recommendations are based upon foam kits being stored in a cool, well-ventilated area. Ideal storage temperature is 60° - 90°F (16° – 32°C). Storage above 90°F (32°C) and in high humidity will reduce storage life. Do not store at temperatures above 120°F (49°C). Do not freeze.

Straw Foam – Leave straw adaptor attached and bend it backwards. Attach straw end to the plastic protrusion on top of the trigger. Simply pull the straw off the protrusion and reuse later. You may need to trim the end of the straw. Use within 2 weeks.
Gun Foam – Leave the can of foam attached to the gun and reuse later. Use within 30 days.
Two-Component Foam – Each type of container has a specific procedure for shutting down to help prevent issues with restarting later. Consult Technical Bulletin, "Stopping and Re-starting”.

What are the optimal temperatures for foam application?

For best results apply Touch ‘n Seal spray foams when surface and ambient temperatures are between 60° - 90°F (16° – 32°C). Chemical components must be between 70° - 90°F (21° – 32°C) before dispensing.

Storage Of Unopened Foam Containers

Always store foam upright in a cool dry place (60°-90°F / 16°-32°C).
Never store foam containers in your car or truck, near fire or flame or where temperatures may exceed 120ºF/49°C.
Always check the product label for application and storage temperature ranges.
Keep out of reach of children.

GENERAL TOUCH ‘N SEAL FOAM APPLICATION

Can I spray Touch ‘n Seal products into an enclosed space or cavity, such as behind drywall?

No. Touch ‘n Seal systems are designed to be applied to open cavities and voids. The expansion of foam creates pressure against the surfaces of an enclosed void and may result in deformation. Drywall my bow or buckle if foam is sprayed into an enclosed wall cavity.

Touch ‘n Seal Slow Rise Two-Component Foam is designed to fill enclosed voids where the cavity is constructed of strong rigid materials such as metal.

If high-pressure expansion is a concern, you may be interested in our No-Warp Foam Window & Door Insulating Sealant, or our Quick-Cure Reduced Expansion Cylinder Foam.

How do I read date codes on foam containers

Please refer to document 10004 How to read date codes on foam containers.

ONE COMPONENT FOAM USE

Do I have to clean my gun foam applicator after each use?

The internal workings of the gun foam applicator do not need to be cleaned after every use. Clean when you notice product is beginning to dispense slowly or if you will not be using the applicator for a lengthy period of time (> 30 days). Leave a can of gun foam attached to the applicator at all times if you are not planning to clean the applicator with polyurethane foam cleaner.

Do I have to use all the foam in a can of gun foam at one time, or can I restart a partially dispensed can later?

You can restart a partially dispensed can as long as you leave it attached to the gun, stored in a cool dry place less than 30 days.

How do I apply gun foam?

Screw the can of foam onto the basket of your gun. Apply a test bead on cardboard to get a feel for the amount of foam you want to dispense. Adjust the output knob, to control the desired flow of foam. Always read the label for application and disposal instructions. One component PUF is bead applied; not sprayed.

How do I dispose of a can once I’m finished?

Fully dispense all the foam and pressure in the can. Dispose of the empty can per your local regulations. Always read the label for application and disposal instructions.

TWO-COMPONENT FOAM USE

How much coverage will I get with a Two-Component Foam Kit?

A number on the upper right hand corner of the package front will indicate theoretical* spray foam output. A board foot is defined as 12” x 12” square by 1” thick. A Foam Kit 110 will provide 110 board feet theoretical output, a Foam Kit 600 will provide 600 board feet theoretical output, etc. Reference the product Technical Data Sheet for cubic feet.

*Theoretical yield is used as an industry standard to represent the size of two-component foam kits. The calculation is based upon ideal conditions, does not include blowing agent loss, and may vary according to application method or environmental factors.

Why did the spray foam not cure properly?

The most common causes of improperly cured foam are:

Improper ambient, chemical or substrate temperature
A clogged spray foam applicator caused by attempting to spray foam with a mixing nozzle that was filled with cured or partially cured foam. Replace mixing nozzles after 30 seconds of non-use.
Chemical valves may not have been fully opened
Chemicals were beyond expiration date
Failure to flush chemical hoses with fresh chemicals weekly, in partially dispensed foam kits, leading to clogged “A” side hose.
Partially discharged foam kits were not used within 30 days of initial dispensing.

Can I temporarily store a partially dispensed foam kit for use later?

Yes. Please refer to Technical Bulletin “Stop & Restart”

How do I assemble my two-component Foam Kit?
Two-Component Foam assembly instructions

How do I dispose of my empty two-component foam kit?
Please refer to Technical Bulletin “Disposal of Used Containers"

FIRE SAFETY

Are Touch ‘n Seal Polyurethane Foams Combustible?

Yes. NEVER use spray polyurethane foam around fire or flame. All polyurethane spray foam is combustible. ALWAYS apply two-component foams in multiple, thin, sweeping layers no more than 2” thick. Allow foam to cool between the application of additional layers. The foam chemistry generates heat during expansion, and multiple, thin layers will prevent heat build-up and reduce the potential for combustion.

Are your foams fire retardant?
All of our one-component gun and straw foams are Class 1 rated fire retardant.

Many of our two-component spray foams are Class 1 fire retardant. All two-component Class 1 fire retardant spray foams are designated by the term “FR” in their product name.

Refer to product Technical Data Sheets and ICC-ES reports for detailed performance and code compliance information.

Will “fire retardant” foams or caulks stop or prevent a home or building fire?

No. These products are intended to resist flaming, and retard the spread of flame, smoke and noxious gasses within a structure. They offer critical minutes to help enable escape.

Touch ‘n Seal offers 3 products that provide enhanced protection from flame, smoke and gas in the event of a fire.
