JB8800 Silicone Sealant for Insulating Glass Primary Seal is a high performance sealant suitable for sealing, bonding,
repairing and mending of glass
and window construction, double glazing in windows, aquariums, shower screens and sanitary ceramics
JB8800 Silicone Sealant for Insulating Glass Primary Seal exhibits an excellent adhesion to glass tiles ceramics, fibreglass, aluminum, no-oily woods,
painted surfaces, plastics and other non-porous surfaces.
Two-component, neutral-curing silicone sealant specially designed for insulating glass assembly. The product's formula design makes it have high modulus,
high strength and other properties to meet the requirements of insulating glass assembly. At the same time, it has the advantages of weather resistance, high
and low temperature resistance and good adhesion of ordinary silicone sealants, and also has the characteristics of low air permeability. Good compatibility
with other neutral silicone adhesives.
Feature
1.Two-component, neutral-cure, high modulus silicone sealant;
2.Excellent resistance to weathering;
3.Excellent cohesiveness with most of construction material without priming;
