Detail:
- 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
