Pigmented, solvent based primer for metal substrates.
Sika Primer-204 N is a solvent-based yellow primer, which reacts with moisture and forms a thin layer. This layer acts as a link between substrates and adhesives. Sika Primer-204 N is specifically formulated for the treatment of bond faces prior to application of Sikas 1-component Polyurethanes. This primer might provide excellent adhesion without previous activation step on certain substrates.
Sika Primer-204 N is used to improve adhesion on metals like steel, stainless steel, galvanized steel, aluminium and anodized aluminium. Sika Primer-204 N is not suitable as an anticorrosion paint. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.
