Features & Benefits


  • Chromate free
  • Ease of use
  • Quick drying

It can be used as a 1 pack when mixed with thinner 2691 or 2711, or as a 2 pack wash primer when mixed with HMG 2K Etch Activator KR08 (see application details).

Product can be overcoated with most HMG primers and can be used in conjunction with powder coatings.

It is no longer recommended to use an etch primer under an epoxy primer.  Residual acid from the etch primer can interfere with the proper curing of the epoxy.  This may lead to extended dry times, potential blistering, and even adhesion failure.  So next time you are planning to paint bare metal with an epoxy, follow the recommendations on the datasheet and use the epoxy directly on the properly cleaned and sanded bare metal substrate.
