Ready to use, 1K filler for car body repairs. Dedicated especially to plastics as a adhesion promoter.


  • Perfect adhesion to plastics.
  • Easy application.
  • Very short hardening time.


It is designed to be applied on surfaces made of various kinds of plastic, especially polypropylene, PP, and its mixtures.

Note: The coating does not improve the adhesiveness to the surfaces made of polyethylene, PE.

The surface designed for painting should be carefully degreased with detergent and wiped with abrasive non woven fabric in advance. Then it should be again cleaned with detergent, rinsed with water and dried with air.

It is recommended to heat the element at the temperature of 500 C prior to commencing painting work, which will help to remove silicone compounds from its surface.
