SQ881 is two-component, neutral cured, specially designed for the second sealing of insulating glass.

Introduction:

SQ881 is two-component, neutral cured, specially designed for the second sealing of insulating glass. The sealant has excellent adhesion to most building materials without priming paints and outstanding resistance to air aging.

1. It is two-component, curing time adjustable, applicable for construction at factory. 

2. Neutral cure, non-corrosive for construction material, such as metal, coated glass and etc.

3. High elasticity and high modulus.

4. No irritating or smelly odor for the low molecular ethanol emitting when cured.

5. Excellent ageing resistance, weather resistance, ultraviolet resistance, ozone resistance, water resistance.

6. Excellent low temperature resistance, no stiffness or cracking at 30 degree below zero after cured. Excellent strength and flexibility at 90 degree above zero without softening or degradation

7. Good compatibility with other neutral silicone sealant.

8. High movement capability ±20%.

9. Non-pollution.

Usage: Mainly for structural assembly of curtain wall, also for the installing and sealing of the weather proof glass in automobile and ship.
