Teroson PU 8517 H is a black polyurethane-based primer formulated as a thin, solvent-containing liquid. It is free from chlorinated hydrocarbons and aromatic solvents, ensuring safer handling. The product functions as an adhesion promoter, enhancing bonding of polyurethane adhesives and sealants to glass, glass ceramics, plastics, metals, and painted surfaces. It is easy to apply with felt applicators or brushes and dries quickly at room temperature, forming a reliable primer layer with strong reactivity.
Primer for glass and glass ceramics in polyurethane adhesive/sealant bonding
Adhesion promoter for plastics, painted surfaces, and metals
Used in automotive glass bonding, construction, and industrial assembly
Not suitable if primer has thickened, or if the bottle has been opened more than 10 times
Should not be applied directly from the original bottle (must be decanted before use)
