Sika® Hybriflex® 40

Sika® Hybriflex® 40

A high modulus, one component, hybrid based adhesive

Sika® Hybriflex® 40 is a high modulus, one component, hybrid based adhesive which adheres strongly to most substrates. Provides excellent mechanical resistance, resistance to most common chemicals and solvents and can be overpainted when cured.

  • Excellent chemical resistance.
  • Excellent resistance to solvents when cured.
  • Bonds to concrete, wood, metal, aluminium, polyester, glass, uPVC, stone, ceramics, etc.
  • Over paintable with water based gloss and emulsion paints - preliminary test required before use.
  • Moisture cure.

Joint Design

Joint depth should never exceed width.  Where joint depth does exceed width, the user should use Fix & Fill Expanding Foam or Joint Backer Rod. Ensure that the joint design only permits adhesion to two surfaces, as three-sided adhesion will impair flexibility.
Joint Calculation
Joint widths are calculated according to BS6213:
Width = M x 100 + M
                    F
Where M = movement and F = movement accommodation factor

Application steps

APPLICATION INSTRUCTIONS

All surfaces must be clean, dry and dust free. All loose or flaking surface coatings, and old sealant and mastic joints, should be removed before application. Glass, metal and aluminium should be cleaned with a proprietary solvent cleaner prior to application for optimum adhesion. When using solvents, always ensure adequate ventilation. Avoid heat, sparks and open flames. Observe and follow all precautions listed on the solvent container label. It is not recommended for application to surfaces that are below +5 °C as it is impossible to guarantee a dry, frost-free surface at these temperatures.
 

Priming

  • On porous substrates like concrete use Sika® Primer 3N.
  • On non-porous if needed use silicone Sika® Aktivator 205.
  • Metals – Priming not always necessary.
