Severe Adhesion Weatherproof Building Silicone Sealant
is a high quality, low modulus, anti-fungal, neutral curing sealant.
The silicone sealant is compatible with all kinds of structural silicone sealant and most adhesives, it has excellent adhesion to alumimum, PVC, stone, ceramic, concrete, metal, plastic, vinyl, wood and most building material, with outstanding weatherproof ability make it good at using outdoor condition.
Use: The sealant especially designed for outdoor use, building aluminium panel, curtain wall and outdoor decoration, offers resistance to sunlight, rainwater, snow, ozone and extreme temperatures. It easily extrudes in a wide rang weather condition and quick cures, the cured sealant can maintain its elasticity in temperatures of -50ºC to 150ºC without hardening, cracking or degrading, weatherproof sealant alos can be used for the sealing of vertical and wide joints without slumping
