Description

One-part, neutral curing, low modulus silicone sealant with high adhesion for perimeter sealing and glazing applications.

Features and benefits:

  • Cures at room temperature under atmospheric moisture.
  • Produces a permanently flexible silicone rubber.
  • Has a primerless adhesion to most materials.
  • Non-corrosive to metals.
  • Non-sag.
  • Quickly becomes tack free due to rapid crosslinking.
  • Remains flexible at low and high temperatures (-40°C to 150°C).
  • Good weather resistance.
  • Low dirt pick-up.
  • Anti-fungal to prevent mould growth.
  • CE marked.

Applications:

Suitable for alkaline substrates such as concrete, mortar and fibrous cement.

Conforms to/ approved by:

The harmonized European standard, EN 15651, for facade, glazing, cold climate, sanitary and pedestrian walkway applications in compliance with the 'Construction Product Regulation'.

Should not be used as a secondary sealant in insulating glass units or for structural glazing bonding. Not to be used with coating materials (paints and varnishes) or organic plasticizer containing rubbers (EPDM, butyl and neoprene). Not suitable in use with natural stones such as marble, granite or quartzite. Not recommended for long term use under water. Not suitable for food contact applications.
