  • 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

Basic Uses

  • 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
