EVERBUILD® EVERFLEX® 700T Silicone

EVERBUILD® EVERFLEX® 700T Silicone

Fast cure, low modulus, neutral cure sealant for the PVCu and Roofline Industry

EVERBUILD® EVERFLEX® 700T Silicone is a low modulus, neutral cure RTV silicone sealant that adheres to a wide range of both porous and non porous surfaces without the need for priming. EVERBUILD® EVERFLEX® 700T Silicone is formulated to a high viscosity to give excellent tooling properties.

  • Excellent adhesion - adheres to most common surfaces including glass, metals, plastics and wood.
  • Low dirt pick up - important in PVCu work.
  • Good external weathering properties.
  • Suitable for use on polycarbonate.
Application Temperature Resistance +5 °C to + 40 °C Elongation at break>200 % ISO8339

Joint Design

Maximum depth 50 % of joint width; movement capacity will be impaired if the depth of the joint is greater than the width. For maximum movement accommodation, it is recommended that:

  1. The joint depth should be no less than 5 mm
  2. Joint depth should be 5 mm for joints up to 10 mm wide
  3. Joints above 10 mm in width should be half the width in depth up to 20 mm 

For deep joints, reduce depth by using Fix and Fill Expanding Foam or a suitable joint backer rod.

All joints should be designed so that the seal is placed in a position which does not retain water or form a water trap. Triangular fillets should be no less than 12 mm across the face and should be finished with a flat or convex face.

Application steps

SUBSTRATE PREPARATION

The surfaces must be clean, dry and free from dust, grease and other contaminants. As quality of plastics can vary, always carry out adhesion tests prior to large scale use.

Improve adhesion by wiping surface with PVCu Solvent Cleaner or white spirits (painted surfaces). Priming is generally not required, although we always advise testing small areas prior to use. Prime with Sikaflex Primer 3N for porous and Aktivator 205 for non-porous substrates if priming is to be conducted.
