3M™ Silane Glass Treatment AP115, Clear, 4 oz Bottle, 20 per case

3M™ Silane Glass Treatment AP115 is an IPA based silane glass treatment that is used in conjunction with 3M™ VHB™ Tape to promote adhesion. It is easy to apply using the 4 fl. oz. spray bottle and is also available in a 1 gallon bulk bottle. It is clear in color.

Promote Adhesion to Uncoated Glass Surfaces
Our 3M™ Silane Glass Treatment AP115 is a solvent mixture of isopropyl alcohol and water that is used to increase adhesion of 3M™ VHB™ Tapes to uncoated glass surfaces. Glass surfaces are water loving in nature, which can cause issues in humid or wet environments when attempting to create a strong, long-lasting adhesive bond. Moisture can undercut the tape bondline and interfere with normal adhesion forces. 3M™ Silane Glass Treatment AP115 creates a hydrophobic surface that protects the 3M™ VHB™ Tape and bonds in even the most moist environments. Easy to apply and clear in color

Recommended Applications


Glass treatment in wet or humid enviroments
Construction industry


Application Instructions


Moisten a clean, soft absorbent, lint-free cloth with the silane solution (or spray solution onto surface) and wipe the area to be bonded in one direction. Immediately follow with a dry lint-free cloth (two-cloth method).  A thin “mono-layer” of the silane solution gives the best results.
The glass should be completely dry with no film residue visible.* Under normal room temperature conditions it is best to wait 1 to 2 minutes before applying the tape so that any residual moisture can evaporate.
Apply 3M™ VHB™ Tape within 15 minutes after treating the surface to minimize the risk of recontamination of the surface.
