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


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.


SV777 is designed to meet or even exceed the requirements of:

Chinese national specification GB/T 14683-2003 20HM


SV777 should be stored at or below 27℃ in original unopened containers. It has a shelf life of 12 months from the date of manufacture.
