Usage
Sikaflex®-291 is a multipurpose product for use in marine constructions. It is suitable for making elastic, vibration-resistant joint seals, and can also be used for a variety of interior sealing applications. Sikaflex®-291 bonds well to the materials commonly used in marine construction like wood, metals, metal primers and paint coatings (2-C systems), ceramic materials and plastics (GRP, etc.). Sikaflex®-291 must not be used to seal plastics that are prone to stress cracking (e.g. Plexiglas, Polycarbonate, etc.). Once cured, Sikaflex®-291 can easily be sanded as required. This product is suitable for experienced professional users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.
Pigmented, solvent based primer for paints and plastics
Sika® Primer-209 D is a solvent-based, black primer that reacts with moisture and forms a thin layer. This layer acts as a link between substrates and adhesives.
Sika® Primer-209 D is specifically formulated for the treatment of bond faces prior to application of Sika’s 1-component Polyurethanes. This primer might provide excellent adhesion without previous activation step on certain plastic substrates.
Sika® Primer-209 D is used to improve adhesion on many plastics and paints such as GRP, epoxy resins, PVC, ABS, PMMA, PC, PS, acrylics, alkyds/melamine, powder coatings and baking varnishes.
Due to the wide variety of plastics, it is mandatory to perform preliminary tests on original substrates under production conditions.
Seek manufacturer’s advice and perform tests on original substrates before using Sika® Primer-209 D on materials prone to stress cracking.
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.
