One Part Weatherseal Silicone Sealants are predominately designed as a high performance architectural grade sealant. These types of sealants are mainly used on high-movement façade work, where the sealant is designed to keep the elements out, even under harsh conditions and temperature extremes.

Typical applications include substrates like:

  • Glass
  • Aluminum composite materials
  • Curtain wall joints
  • Expansion and control joints

These products are currently available at APTC Australia in cartridge and sausage/sachet packaging.
