• Silicone durability - cured silicone rubber exhibits excellent long term resistance to natural weathering
  • Adhesion - primerless adhesion to many substrates and finishes
  • ±50% Movement capacity - can accommodate 50% movement in both extension and compression and has excellent recovery after cycling
  • Low VOC
  • Strength properties - SilPruf's combination of high tensile strength, high tear strength and the capacity to absorb high deformations (elongation) make this product an outstanding candidate for protective glazing designs and seismic applications
  • Thermal stability - once cured, the material remains elastic over a range of -48°C to 149°C and up to 204°C under intermittent short-term exposure
  • Stable consistency - supplied as a lightweight paste, the consistency of which remains relatively unchanged over a wide temperature range
  • Extended work life
  • Low sag or slump
  • Packaging - 600 ml sausage
  • Weatherproofing - between dissimilar or similar materials in either new or remedial glazing and sealing applications, around window perimeters and punched openings
  • Protective glazing - successfully tested in protective glazing designs
  • Adhesive - applied in panel stiffener applications
