3 Reasons Not to Use Polyvinyl Acetate as a Metal Adhesive

When you are looking for an adhesive to bond metal, polyvinyl acetate is not the right choice. Polyvinyl acetate is manufactured by a chemical process involving vinyl acetate. It is a thermoplastic polymer. There are several reasons why polyvinyl acetate does not make a good adhesive for metal. The article below will explain some of these reasons.

1. Water Soluble

The major downfall of using polyvinyl acetate as a metal adhesive is the fact that it essentially melts in water. This means that you could never get the metal wet. Even exposure to high-temperature steam will cause the polyvinyl acetate to disintegrate.

2. Alcohol Interference

Polyvinyl acetate, like most acetates, do not like alcohol. The chemical construction of alcohol interferes with the adhesion of the polyvinyl acetate. Wiping down metal that has been bonded with polyvinyl acetate will cause the acetate to dissolve.

3. Bonding Inferiority

In order for metal to bond to metal or any other material, it needs to have some sort of texture. If this texture is not present, then the material will not bond. This is, unless of course, the bonding agent is specifically formulated for these surfaces. Polyvinyl acetate is not one of these bonding agents.
