Colourless transparent special adhesion promoter for metal substrates of all kinds. Can also be used on problematic substrates such as anodised aluminium or copper without grinding. No discoloration of a subsequent clear coat due to colorless setting. Can also be used as a transparent plastic primer. Equally universally applicable plastic primer for use on plastics commonly used in the automotive sector (e.g. PP-EPDM, ABS, PC, ABS-PC, PMMA, PA, PUR, PVC, GRP). Due to the special formulation, however, adhesion to other, difficult surfaces without prior sanding is also possible without any problems. It can be used on steel, aluminium (also polished or anodised), galvanised substrates, stainless steel (also polished), non-ferrous metals (also polished), chrome-plated substrates, powder coatings and KTL coatings. The material offers great time savings due to fast drying and recoatability as well as the elimination of sanding work. Can be repainted with Mipa 1K and
