  • Cures to a tough, flexible silicone elastomer
  • Resistant to ozone, ultraviolet (UV) radiation and temperature extremes


Typical Uses

  • Industrial sealing and bonding
  • Formed-in-place gaskets
  • Waterproofing rimless sinks
  • Sealing around shower-tub enclosures, sinks, urinals and whirlpools
