Description
Sika® Primer-210 is a low viscosity liquid primer to improve adhesion of Sikaflex® products on various substrates. Sika® Primer-210 is manufactured in accordance with ISO 9001 / 14001 quality assurance system and the responsible care program.

Areas of Application
Sika® Primer-210 is used to improve the adhesion of Sikaflex® adhesives on many metals such as aluminum and galvanized steel, plastics and paint-primed substrates. This primer is also suitable to enhance the adhesion of Sikasil® sealants and adhesives on porous and non-porous substrates. 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.

Method of Application
Surfaces must be clean, dry and free from grease, oil and dust. Pretreat the bond face of non-porous substrates with Sika® Cleaner-205 and leave to dry. For use with Sikasil® products on non-porous substrates pre-treatment with Sika® Cleaner-P (wipe-on/wipe-off) is also possible. Apply a thin but covering coat of Sika® Primer-210 with a brush, felt or foam applicator. It shall be applied once only. Care must be taken to ensure that this single application gives adequately dense coverage. Sika® Primer-210 exhibits thermoplastic behaviour for up to 3 days following application. Ideal application and surface temperature is between 15°C and 25°C (60°F to 75°F). Consumption and method of application depend on the specific nature of the substrate
