Technical Information

DOWSIL 732 in the 300 mL cartridge format delivers the same trusted clear silicone sealant chemistry in a larger, gun-applied package designed for higher-volume sealing jobs. The 300 mL cartridge is compatible with standard skeleton and pistol-grip caulk guns, enabling consistent bead application on large glazing joints, expansion gaps, and assembly sealing operations. Like the tube variant, it cures by moisture to a tough silicone elastomer with strong adhesion to glass, metal, ceramic, and plastic substrates. The larger format reduces material handling frequency and lowers per-unit cost for production and maintenance operations requiring significant sealant volumes.
