Antas-193-25 Silicone Weatherproof Sealant

Packaging : 300mL, 590mL

Antas-193-25 is a one component, neutral curing, silicone sealant with properties of high weather resistance, wide temperature tolerance, high movement capacity. It is used in weatherproof sealing of all types of glass and metal curtain walls, roofs and gutters.
Product feature
  1. Easy to use with good tooling and non-sagging properties at 5 to 45°C
  2. No corrosion or staining to metal, stone, ceramic tiles or most common building materials
  3. Movement capacity of ±50% for effective sealing in curtain wall or roofing applications
  4. Excellent weather durability, resistance to UV and hydrolysis.
  5. Wide range of temperature tolerance, with good elasticity within -50 to 150°C
Main purpose
  1. Bonding joints with high performance of weatherability for curtain wall.
  2. Sealing the gap of the construction wall.
  3. Other bonding and waterproofing for general purpose.
