UV Bonding FAQ - Material

Q: Can I bond glass, which is not ground and polished?

A: This will not work well, as differences in the layer thickness of the adhesive will lead to tensions in the bonding area, which will result in cohesion cracks in the adhesive and finally the destruction of the bond.

Q: Can I bond to the backside of the mirror?

A: Due to safety reasons, we advise not to produce such bonds, as the bonding will be only as good as the adhesion of the mirror backing.
