DOWSIL™ 895 Structural Glazing Sealant is a one-part, neutral curing silicone sealant designed specifically for the structural bonding of glass, metal, and other building components. It can also be used to adhere stiffening elements to building panels and for other similar adhesive applications.

Features:

  • Meets the newly developed European standards for structural glazing application, as developed by EOTA.
  • Excellent adhesion to a wide range of substrates including coated, enamelled and reflective glass, anodized and polyester coated aluminium and stainless steel profiles.
  • Odourless and non-corrosive cure system.
  • One-component product.
  • Resistant to ozone and temperature extremes.

Benefits:

  • The cured product exhibits excellent weathering characteristics, and a high resistance to ultra-violet radiation, heat and humidity.
  • High ultimate tensile strength makes it ideally suited for structural bonding applications.
  • Excellent mechanical properties.

Standards:

DOWSIL™ 895 Structural Glazing Sealant exhibits a high level of physical properties and adhesive performance which are retained even after aging as detailed by EOTA:

  • 2000 hours exposure to ultra-violet radiation in hot water immersion (ISO DIS 11431, UBAtc ATG00/H716).
  • 5000 load cycles in tension (ISO 846, UBAtc ATG00/H716).
  • Resistance to SO2 and salt spray (ISO 3231 and ISO 9227 NSS, UBAtc ATG00/H716).
  • Resistance to cleaning agent (ISO/DIS 10591).
  • Resistance to extreme temperature (EN 28339, UBAtc ATG00/H716).
  • 4000 hours exposure to ultra violet radiation under maintained extension at 12.5% (Ref: CSTB GM 908).
