Antas-189 Acetoxy Sealant for Bigboard Glass

Packaging : 300mL


Antas-189 is a one component, acetic curing silicone sealant. It cures by absorption of atmospheric moisture to form a flexible and durable elastomeric sealant. It can be specifically used for glass curtain wall, glass rooftop, aquariums.
Product feature
  1. One-component, acetic curing, and fast curing, high tensile strength and without color changing.
  2. Excellent adhesion to most building materials, easy to use.
  3. Excellent weathering performance and ozone-resistant, UVresistant and extreme high-low temperature capability.
  4. Wide range of temperature tolerance with good elasticity within -50ºC to 150ºC.
  5. No sag, and can be used for adhesion of vertical or overhead interface.
Main purpose
  1. Sealing between the glass and window/door frame
  2. Sealing glass joints
  3. Sealing shopping window and sunshade
  4. Sealing aquarium
