HN-620 A/B is an industrial-grade milky-white, soft RTV2 tin cure (condensation cure) liquid silicone rubber, mixed at 100:2 and vulcanized at room temperature. With high tear resistance, low shrinkage and good fluidity, it is engineered for building molds used in artificial stone production, cultured marble casting, cement and gypsum reproduction, and architectural casting.

Key Features

  • Strong tear resistance, high & low temperature resistance, acid & alkali resistance, aging resistance
  • Low linear shrinkage (≤0.2%, i.e. ≤2‰) for accurate, repeatable reproduction of intricate detail
  • Soft, milky-white cured rubber — easy demolding, finished product will not turn white
  • Good fluidity, self-leveling, easy bubble release and easy pouring
  • Mold can be turned over many times with long service life; non-toxic and odorless
  • ROHS & SGS certified; color, hardness, viscosity and operating time adjustable on request (OEM/ODM)
