XILFLEX Structural

about-3

XILFLEX® Structural is a one-part, high-strength neutral cure, CaCO3-reinforced neutral silicone sealant designed for structurally glazed curtain wall applications. It can be used in applications such as factory glazing of unitized curtainwall systems or in field-constructed stick curtainwall systems.

KEY FEATURES

  • One-part – for convenient application.
  • High modulus – for structural applications.
  • Excellent adhesion to many construction materials without primer.
  • Extended tooling time – to accommodate longer working time in construction sites.
  • Durability – silicone sealant naturally shows excellent long term resistance to natural weathering, including extreme temperatures, UV radiation, rain and other atmospheric elements.

SUITABLE FOR

  • Structural applications, weathersealing in low joint movement areas

PACKAGING

  • 280 ml in plastic cartridge
