Material Safety Data Sheet - Merbenit Primer V40


  • Applications
  • Features


Plastics (in plastic-plastic combinations), copolymers, thermovarnished- or powder-coated surfaces. For difficult adhesions on plastics pre-tests are recommended.

The surfaces must be fat-free, clean and dry. For that a specific cleaner (Ethanol) is recommended.
Adhesion Promoter V40 can be put on with a paintbrush. The open-time is at +20°С at least 30 minutes. At latest 2 hours after putting on the Adhesion Promoter the application of the sealant or adhesive is to be done (at the longer waiting times the procedure must be repeated again).
