Are TNFP Spray Insulation Kits water resistant?
TNFP Spray Insulation Kits are water-resistant and form an airtight seal when applied properly. They can be exposed to intermittent water exposure such as rain or lawn sprinklers if allowed to completely dry between exposures. TNFP Spray Insulation Kits are not a waterproof barrier for full-time water exposure.
How should unopened TNFP Spray Insulation Kits be stored?
Store TNFP Spray Insulation Kits 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.
Do TNFP Spray Insulation Kits 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. TNFP Two-Component Spray Insulation Kits 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.
How do I remove wet foam from surfaces?
Use TNFP Foam & Gun Cleaner or acetone and a clean cloth or paper towel. Do Not Apply TNFP Foam & Gun Cleaner or acetone to any finished surface. Always test a small inconspicuous area to ensure TNFP Foam & Gun Cleaner or acetone will not damage the surface. DO NOT USE SOLVENTS TO REMOVE FOAM FROM SKIN.
What is the cure time for TNFP Spray Insulation Kits?
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 (spray foam in a can).
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.
What surfaces will foam stick to?
Examples of substrates to which TNFP Spray Foam Insulation Kits will adhere to are wood, masonry, metals, and drywall.
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.
