antas-332 Modified Construction Silicone Sealant

Packaging : 600ml/sausage
Antas-332 is a one-component modified silicone sealant with room temperature curing and low modulus. It exhibits good adhesion and resistance to weather and stain. It can be brushed with paintings on the surface. Also, it’s environmental-friendly and has excellent adhesion to concrete, calcium carbonate board, fiber cement board, stone, ceramic and other porous materials. It is mainly used for waterproofing and joint sealing of wall panels on prefabricated buildings, also, could be used for joint sealing on other buildings.
