Due to the hydrophilic (water loving) nature of glass the VHB adhesive tape bond may be 'undercut' by moisture getting between the adhesive and the glass surface in applications subject to high humidity and frequent water contact. This causes bond weakening and can lead to adhesive failures from the glass. To combat this effect on such applications the use of a silane primer to prepare the glass is essential.

• The 3M VHB Silane Glass Primer is essential for priming plastic, metal or painted metal glazing bars bonded to glass windows.
• Also an essential primer for bonding letters to glass shop fronts and for bonding glass in bathrooms or kitchens.
• Sold as 1 litre cans
• Recommended for use with 3M VHB tape.
