3M 3901 IN 235 ML BOTTLE

3M 3901 - STRUCTURAL ADHESIVE PRIMER

3M 3901 is a primer for Scotch-Weld film and liquid adhesives in those applications where it is desired to obtain improved metal and glass adhesion or improved resistance to environmental exposure with epoxy and urethane adhesives.

3M 3901 offers the following advantages.

- Insures complete wetting of film adhesive to adherend surfaces.

- Simplifies production scheduling by protecting the cleaned surfaces until the bonding operations can be completed.

- Imparts improved corrosion protection to metal.

Applications :

A thoroughly cleaned, dry, grease-free surface is essential for maximum performance.

Cleaning methods which will produce a break-free water film on metal surfaces are generally satisfactory.

Surface preparations should be fully evaluated with the adhesive, especially if resistance to specific environments are anticipated.
