One-step auto glass primer

Characteristics:
DINITROL 538 plus is a one-stage black primer with additional properties for bonding auto glass with PU adhesives. It is a solvent primer maturing on the basis of physical and chemical processes with high adhesion on glass and ceramic screen printing. This ensures the retention of the PU adhesive system during vehicle operation. It also provides the glued joint with protection against UV radiation. Primer DINITROL 538 plus must be used in the adhesive joint for the following purposes: - as a one-step primer for the ceramic strip of auto glass (additional protection of the adhesive joint against UV radiation) - pretreatment for RIM tapes and varnishes - primer with a long open time (up to 3 months) - corrosion protection for minor paint damage on the body flange - usable for all PU adhesives DINITROL (EFTEC)
