Description

A sanitary, high modulus, acetoxy cure silicone sealant and adhesive which possesses good tooling properties.


Features and benefits:

  • Highly elastic: Suitable for use around the building envelope for industrial, commercial and domestic applications where a highly elastic product that does not shrink or crack is required.
  • Easy to tool: Good tooling and application characteristics with a stiffer, more viscous formulation for the applicator.
  • Good adhesion is achieved to a variety of non-porous substrates including: Glass, ceramics, aluminium and painted timber.
  • Typical acetic cure odour.
  • High modulus, acetoxy cure (20LM).
  • High ultraviolet (UV) radiation, ozone and temperature resistance.
  • CE marked to EN 15651-2: G-CC–20LM and EN 15651-3: XS1–20LM.
  • Non-flammable.
  • Viscous formulation returns superior gunning and tooling characteristics preferred by the professional sealant applicator.
  • Conforms to EN 15651-3: CLASS XS1.
  • Base technology: Acetoxy; one component; RTV silicone polymer.
  • Slump: Non-sag.
