SV-777 silicone sealant for stone

Short Description:

SV-777 silicone sealant for stone, is an elastomer sealant in modulus, single. Waterproof joints need to be sensitive to natural stone, glass and metal building clean appearance panel for sealing design, it to the moisture in the air after curing in contact, the formation of elastic rubber sealing performance, durability, weather resistance, good combination with most building materials.

Product Information

CURE TIME

As exposed to air, SV777 begins to cure inward from surface. Its tack free time is about 50 minutes; the full and optimal adhesion depends on the sealant depth.
