Black multi-primer for pretreatment of various surfaces




Good Stock

Product description:

The multi-primer DINITROL 550 is a solvent-based physically and reactively drying black primer. The primer is intended as a pre-treatment for several lacquers, but also as a pretreatment for different metals and different types of plastics.

The surfaces to be bonded must be clean, dry and free of grease. In most cases, we recommend roughening the substrate with a non-woven web.

For further pre-treatment, it is necessary to apply the adhesion promoter DINITROL 520 before applying the black DINITROL 550. The test with the actual substrates and conditions must be prefabricated to guarantee adhesion and material compatibility.

From August 24, 2023, proper training is mandatory prior to industrial or commercial use. For more information on training opportunities, please refer to the Training for users file.
