Product Details
silicone sealant for stone with weatherproof neutral silicone
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.
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.
SPECIFICATIONS
SV777 is designed to meet or even exceed the requirements of:
Chinese national specification GB/T 14683-2003 20HM
STORAGE AND SHELF LIFE
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.
Basic Application
1. Stone curtain wall sealing
2. Engineering ceramic sealing
3. Stone and other materials such as glass, metal seam sealing
4. Other uses
