Expanding PU Foam

DEscriptION

TYL®-Foam S is modified one component polyurethane foam for filling or sealing of joints and gaps. The foam expands rapidly after dispensing and quickly cures to fine honeycomb structured foam by reacting with atmospheric moisture. It forms a strong bond to most constructio0n materials, such as concrete surface. TYL®-Foam S is supplied in pressurized aerosol canisters in Nozzle grades.

Uses

1. Filling of cavities

2. Sealing of all openings in roof constructions

3. Apply of an acoustic baffle

4. Apply of sound absorbing layer

5. Installing window and door frames

Advantages

1. High filling capacity

2. High insulation value, thermal and acoustic

3. Very good bonding properties

4. Excellent stability non shrinkage or post-expansion

5. Free of HCFC, CFC and no other ozone depleting

6. Water Resistant

Application Method

Shake the aerosol can for at least 20 seconds. Fit the gun on the adaptor. Surface should be from grease and dust. Moisten surfaces with a water sprayer prior to application. Fill holes and cavities for 60%, as the foam will expand. Repeat shaking regularly during application. If you have worked in layers repeat moistening after each layer.
