▶Product Advantages:
1.Original grade high strength
2.Solvent-free and odorless
3.Cures quickly
4.Brushed short
5.Anti-sagging
6.Primer-free bonding on glass
7.Easy secondary removal

▶Applications:
Window glass bonding for OEM and repair markets, original glass bonding with standard modulus for all vehicles (including windshields with full antennas, aluminum structure body, etc).
When primer-free construction, the glass surface needs to be treated with a glass cleaning activator that does not generate static electricity to ensure that the surface to be bonded is pollution-free. We offer you easy-to-use glass cleaning activator wipes.
