Antas-195 Silicone Weatherproof Sealant For Stone

Packaging : 300mL, 500mL, 590mL

antas-195 is one component, neutral curing, silicone sealant with good adhesion to porous stone and ceramic materials without pollution. It is specifically designed for weather resistant joint sealing in stone cladding and stone constructions.
Product feature
  1. Good adhesion to all types of marble, granite and ceramic tiles with no oily stain marks
  2. Easy to use with good tooling and non-sagging properties at 5 to 45°C
  3. Movement capacity of ±35% for effective sealing in stone facade.
  4. Excellent weather durability, resistance to UV and hydrolysis
  5. Wide range of temperature tolerance, with good elasticity within -50 to 150°C
  6. Compatible with other neutrally cured silicone sealants and structural assembly systems
Main purpose
  1. Sealing joints with high performance of weatherability for stone and ceramic cladding and construction.
