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.
