Compatible substrate materials include wood, metals, (particularly aluminum including anodized components), sheet steels (including phosphated, chromated and zinc-plated components), metal primers and paint coatings (two-part systems), ceramic materials, plastics and glass.

Characteristics & Advantages:

  • Very low VOC/solvent free
