Description

Professional Silane Primer for Enhanced Adhesion to Glass

3M Silane Glass Primer is a high-performance surface preparation product formulated to significantly improve bonding between glass and adhesives, especially in environments where moisture can compromise adhesion. Based on silane chemistry, the primer modifies the glass surface to create a moisture-resistant, adhesive-friendly layer - ideal for maximising bond strength when using 3M VHB tapes.

Combats Moisture Resistance for Reliable Long-Term Bonding

Glass surfaces naturally resist bonding due to their smooth, chemically inert nature and sensitivity to moisture. This primer addresses both challenges:

  • Improves wet-out of adhesives on glass.
  • Reduces moisture related adhesion failures.
  • Enhances long-term durability in humid or wet environments.

This makes it particularly effective in high-moisture installations such as kitchens, bathrooms, exterior glazing, and commercial shop fronts.

Essential for Glass Signage, Structural Bonding and Architectural Applications

3M Silane Glass Primer is widely used by installers and sign makers for bonding:

  • Acrylic or aluminium letters to glass shopfronts.
  • Fixtures and fittings in kitchens and bathrooms.
  • Muntin bars and architectural trims.
  • Glass assembly components.

Used with 3M VHB tapes, it dramatically increases initial tack and long-term holding strength.

Fast, Easy, and Clean Application

The primer is ready to use straight from the bottle - no dilution required. It is transparent, allowing clean application without discolouration or residue. After wiping onto the glass surface, it flashes off quickly, forming an invisible, primer-treated layer optimised for adhesive bonding.

Durable 1L Bottle for Workshop and On-Site Use

Supplied in a 1-litre bottle, the primer is suitable for both high-volume industrial use and on-site installation work. Its robust packaging helps prevent damage during transport and ensures reliable storage between jobs.

More Information

Application Instructions

  1. Ensure the glass surface is clean and dry.
  2. If necessary, remove heavy contamination using an appropriate cleaner (e.g. 3M VHB Surface Cleaner).
  3. Shake the bottle gently before use.
  4. Apply a small amount of primer to a clean, lint-free cloth or applicator pad.
  5. Wipe and even, thin layer across the bonding area on the glass.
  6. Allow the primer to dry completely (typically seconds to minutes depending on temperature and ventilation).
  7. Apply 3M VHB tape or adhesive directly onto the primed area.
  8. Ensure full contact and pressure for optimum adhesion.

Usage Notes

  • Use in well ventilated areas.
  • Avoid excess application - apply only a thin, uniform layer.
  • Always test on decorative or coated glass to confirm compatibility.
  • Store tightly sealed to prevent evaporation.
  • Flammable - keep away from heat and ignition sources.
