SV-8800 Silicone Sealant for Insulating Glass with two component neutral-cure silicone sealant for insulating glass
Stretch to the limit to see if there are cracks and breaks? Rebound is not as ever?
High-quality silicone sealant tensile strength, tensile strength, anti-peel strength. Silicone sealant hardness and elasticity is moderate, too hard or too soft silicone sealant are not good silicone sealant
Features
Two-component, neutral-cure, high modulus structural silicone sealant
Excellent resistance to weathering
Excellent cohesiveness with most of construction material without priming
Good compatibility with other neutral silicone sealant
The product A group is white,B group is black, A:B volume is 10:1,weight ratio is 14:1.the color is black after mixed.
Application
Applicable to glass curtain wall structural glazing

CURE TIME
As exposed to air, SV8800 begins to cure inward from surface. Its tack free
time is about 50 minutes; the full and optimal adhesion depends on the
sealant depth.
