SIKA 212FC Sikaflex Polyurethane Sealant, 600 ml, White.

SIKA 212FC Sikaflex Polyurethane Sealant, 600 ml, White.

SIKA 212FC Sikaflex Thixotropic sealant for buses, trucks and trailers. It is a 1-component sealant of paste-like consistency that cures on exposure to atmospheric humidity. It is designed for internal sealing applications.

Suitable for most internal sealing applications in industrial commercial vehicle building. The product possesses excellent sealing properties and bonds well to most materials commonly used in the commercial vehicle industry, e.g. metals, plastics, wood and glass.

Sikaflex®-212 FC bonds to itself, can be sanded and overpainted in its fully cured state. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.

Sikaflex®-212 FC can be painted prior and after formation of a skin. If painting process takes place after the sealant has built a skin, adhesion could be improved by treating the joint surface with Sika® Aktivator-100 or Sika® Aktivator-205 prior to paint process. If the paint requires a baking process (> 80 °C), best performance is achieved by allowing the sealant to fully cure first. All paints have to be tested by carrying preliminary trials under manufacturing conditions.

The elasticity of paints is usually lower than that of sealants. This could lead to cracking of he paint in the joint area.
