550 Primer

The multiprimer DINITROL 550 is a black solvent based physical, reactive drying primer. The primer is designed as a pre-treatment for several paints but also as a pre-treatment for different metals and for different kinds of plastics. Substrate must be clean, dry and free of oil and grease. In the majority of cases we recommend
to rough the bonding area with a very fine scotch brite. For the further pre-treatment it is a must to apply first the adhesion promoter DINITROL 520, before the application of the black primer DINITROL 550. 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
• Corrosion protection on smaller scratches
