Adhesives

Adhesion promoting primers based on polyurethanes and epoxies are excellent for bonding elastomers to metal or ceramic substrates. In addition, these primers can be used to bond polyurethanes to other urethanes and flexible elastomers for more complicated applications. Choose from our specifically formulated adhesive primers for any of your custom needs.

Adhesion promoters for bonding polyurethanes to:

  • Metallic and metal surfaces
  • Wood surfaces
  • Concrete and ceramic substrates
  • Non-polyurethane elastomers
  • Polyurethane elastomers

Polyurethanes elastomers in general, require an adhesion promoting primer to form strong bonds to various substrates.

Primers are chosen based on the type of surface that will be bonded to the polyurethane. The primers are suppled in two forms:

  1. as a two component system where Component A & B are combined then the mixture is applied to the bonding surface
  2. as a single component system where the material is applied with no mixing.

Better bonds can be made by roughing up the application surface with light sanding and cleaning with M.E.K. Thinner coats of primer that are allow to dry form stronger bonds than heavy applications
