2-Part IGU Insulating Glass Units Silicone Sealant
ZK812 Insulating Glass Units Sealant is intended for use as secondary sealant in dual-sealed insulating glass units. A primary seal of polyisobutylene is required to prevent moisture vapor transmission into the airspace in the insulating glass unit. ZK812 Insulating Glass Units Sealant is a two-part formulation. The base (Part A) is a smooth, white paste. The curing agent(Part B) is available in black or gray and is a pourable liquid. Once catalyzed, the material cures to a high modulus, silicone rubber that is intended for IG applications.
FEATURES & BENEFITS: • Two-part, curing speed adjustable and no heating required • Fast curing time • Neutral curing • Non-corrosive • Unprimed adhesion to glass and metal substrates, such as stainless steel and aluminum • Cures to form a durable, long-lasting, high-modulus, flexible, weathertight bond • Non-slump, ideal for factory assembly of insulating glass unit using automated equipment • Low water absorption and low water vapor transmission rate • Excellent high and low temperature resistance, good strength and flexibility at -58°F(-50°C) to 302°F(150°C) • Excellent weather resistance, ozone and UV resistance • Meets GB/T 29755-2013 Specification for Insulating Glass Units
APPLICATIONS: • ZK812 Insulating Glass Units Sealant is intended for use as secondary sealant in insulating glass units of non-structural assembly. Such as insulating glass for doors and windows; Insulating glass for ordinary exposed frame glass curtain wall.
