Product Description

Description:
Surtek 3969 is a one-component elastic bonding adhesive sealant based on silane-modified polymer. It combines the advantages of both polyurethane and silicone, and thus is a new generation adhesive sealant. It is applied for adhesion and sealing with high elasticity and strength. It is heat resistant and cures quickly to form durable.

Advantages:
One component, non sag, easy to apply
Fast Curing lead to high initial tack
Excellent adhesion without activator and primer
Good heat and UV resistance

Applications:
Surtek 3969 can be used for the elastic and dynamic bonding of metal, wood and plastic, and elastic sealing of joints and seams in following industries: bus body, railway carriage, container, equipment engineering, air-conditioning and ventilation, metal and sheet metal working, plastics technology, ship building, etc.
