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

Primer 450

This is an excellent primer for most substrates.

Primary uses include:

  • Most Surfaces
  • Used with all applications of the Speedliner Bedliner System

Primer 450 EU

Similar to the Primer 450 but with reduced V.O.C’s (volatile organic content) the comply with European Air Quality Rule; 540 gram/ VOC per mixed liter

Primer 460 SPX

This product is similar to the Primer 450 with the added benefit of epoxy to form strong bonds to difficult surfaces

Primary uses include:

  • Most Surfaces
  • Used with all applications of the Speedliner Bedliner System
  • Difficult bonding surfaces

Primer 700

This product is similar to the Primer 450 but does not contain any VOC’s

Primary uses include:

  • Concrete and wood surfaces

Primer 800

This product is similar to the Primer 450 but a single component brush on product and required no mixing

Primary uses include:

  • Concrete and wood surfaces
  • Direct to prepared steel surfaces

Primer EMC-3

This is etching primer that is used to allow bonding of polymers to vulcanized rubber i.e. Neoprene and E.D.P.M
