SQ840K two-component polysulfide insulating glass: 1.Used for the secondary sealing of the insulating glass. 2:Best quality

SQ840K two-component polysulfide insulating glass has excellent adhesion to most building materials such as glass, aluminum alloy, galvanized-zinc steel, etc. It can be applied in manual production line or can be used singly or with butyl sealant owing to its low viscosity and quick adhesion and convenient operation.

Product Characteristics:

Two components, room temperature cured.Excellent adhesion.Excellent anti-aging.No solvent and low boiling point material.Non-pollution.

Purposes: Mainly applied in the sealing of IG in construction, traffic and refrigeration industries.
