| Description: This is a 1-part, RTV (Room Temperature Vulcanizing) silicone adhesive sealant. It is one in a range of Acetoxy cure products which are solvent free. During cure, it liberates a very small amount of acetic acid, giving rise to the familiar ‘vinegar’ odour, which quickly dissipates after cure. It exhibits good primer-less adhesion to many substrates including but not limited to; aluminium, nonferrous metals, steel, glass, enamelled surfaces, fabrics ceramics, thermosetting, thermoplastics and wood and cures rapidly at room temperature when in contact with atmospheric moisture. This product is not to be recommended for use with galvanized metals, ferrous metals, copper and its associated alloys or in electronic assemblies. Key Features - Good resistance to chemicals
- Good resistance to further tearing
- Excellent elongation
- High transparency
Key Applications: - Complies with Oekotex 100
- Tin free
- Solvent free
Application: Narrow fabric coating. Due to the tin-free, blocked catalyst, the silicone elastomer requires temperatures of 70 – 80 °C for 30 – 40 min and an air humidity of 5 – 7 % for a complete, non-tacky fixation. A higher air humidity leads to a destruction of the catalyst, whereas higher temperatures lead to a premature skin formation, which inhibits the reaction, so that the silicone layer remains tacky. Thicker silicone layers need longer curing times. A layer thickness of > 5 mm should be avoided. Special remark : Direct contact of certain cosmetic articles (skin creams) with the silicone layer can lead to a change in colour. We therefore suggest to carry out pre-trials in production with these care products in use and to point this out on the ready-for-use products if necessaryCured Product: Standard climate DIN 50 014 - 23/50-2.
