Surtek 3959 is a one-component elastic bonding adhesive based on silicon-modified polymer. It combines the advantages of both polyurethane and silicone, and thus is a new generation elastic adhesive. It is free of silicone, isocyanate and solvent. It cures quickly to form durable elastomer when in contact with moisture at ambient temperature.

A dvantages:
One component, non sag, easy to apply
Good elasticity
Good heat and UV resistance
Environmental friendly

Aplication:
Surtek 3959 can be used for the elastic bonding and joint sealing for metal, wood and plastic. It is widely used at bus body, railway carriage, container, equipment engineering, air-conditioning and ventilation, ship building industries, etc.
