CHT AS1525 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 room temperature cure
  • Controlled through to prevent strike through on textiles
  • Excellent elongation
Application: Applications include but not limited to, textiles, stocking grippers, medical stocking grippers 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
