Hot melt butyl

Foseal Hotmelt butyl sealant is a high-performance butyl rubber-based sealant designed for secondary insulating glass applications. It provides strong adhesion to glass, aluminum, and stainless steel while remaining solvent-free and low-odor. Once cured, it is non-tacky and highly resistant to UV light, temperature extremes, and water immersion.
