552 PMMA Primer

The black primer DINITROL 552 is a solvent based, physical, reactiv drying primer. The primer is designed as a pre-treatment mainly for PMMA but also as a pre-treatment for polycarbonate glasses. Substrate must be clean, dry and free of oil and grease. We recommend to apply the primer directly after the removal of the protective foil. Test with actual substrates and conditions have to be preformed to ensure adhesion and material compatibility. Trials by the supplier are recommended. The product benefits are:
• Pre-treatment on different paints
• Adhesion promoter on diff. metals and plastics
• Applicable with all PUR adhesives from DINOL
