CHT AS1502 RTV, silicone adhesive sealant
Categories: Polymer; Thermoset; Silicone; Silicone, RTV, Adhesive/Sealant Grade

Material Notes: 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’ odor, which quickly dissipates after cure. It exhibits good primer-less adhesion to many substrates including but not limited to; aluminum, non ferrous metals, steel, glass, enameled 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

  • Fast curing at room temperature
  • FDA indirect food contact CFR 21 177,2600
  • EU overall migration EC 1935/2004 framework EN1186-1 and EN1186-3
  • Silver grey in colour
Application: Designed for applications including but not limited to, airport runway lights, sealing of industrial kitchens and stainless steel equipment and surfaces. These products are highly resistant to weathering and aging, largely stable to many solvents, oils, water, sea water, industrial waste gasses, diluted acids, saline solutions detergents, cleaners, propellants and fruit acids.

Cured Product: 7 days at 23+/-2°C and 50+/-5% humidity
