Product manual
antas-172 is one-component, neutral curing silicone sealant for windows and doors, interior and exterior wall caulking seal, sandwich panel and wood walls for sealing. It is widely used and has good adhesion to most of building materials.
Product feature
  1. One-component, easy to use, with good extrudability and thixotropy in the temperature range of 5 ℃ to 45℃.
  2. Neutral cure, no pollution and corrosion on metal, wood, coated glass, concrete and other building materials.
  3. Excellent resistance to weather, UV, ozone and water.
  4. Excellent resistance to high and low temperature, maintain good flexibility at a range of -50℃150℃ after curing.
  5. Good compatibility with other neutral silicone sealants.
Main purpose
  1. Installing window and door, glass glazing, sandwich panel and wood wall
  2. Filling and sealing the gap for outdoor and indoor wall
  3. Other general purposes
