PolyTech Single Component Polyurethane Caulking Foam
The PolyTech single component caulking foam has the best UL rating in the industry.
With Flame Spread and Smoke Index both at 5 under UL ASTM-E-84 Procedures, the outstanding
performance is unmatched in the industry.
The PolyTech single component polyurethane caulking foam is available in "Summer"
and "Winter" formulations. The Single component caulking foam resin is extremely
sensitive to ambient temperatures. The foam has a tendency to flow too fast in high
ambient temperature and too slow in cold weathers. This makes the application process
difficult. By offering "Summer" and "Winter" formulations, the ease of usage is
greatly enhanced.
