Product Description

Industrial Grade RTV2 Tin Cure Liquid Silicone Rubber for Gypsum Craft Molds — HN-640 A/B

HN-640 A/B is an industrial-grade, two-component RTV2 tin cure (condensation cure) liquid silicone rubber, mixed at 100:2 and vulcanized at room temperature. With an easy-foaming, high-fluidity formulation, high tear resistance and low shrinkage, it is a cost-effective choice for gypsum craft molds, construction molds and general industrial mold making, supplied in bulk for factory production runs.

Key Features

  • Easy foaming and excellent fluidity — self-leveling, easy bubble release, easy pouring
  • Strong tear resistance, high & low temperature resistance, acid & alkali resistance, aging resistance
  • Low linear shrinkage (≤0.2%, i.e. ≤2‰) for faithful reproduction of fine detail
  • Molds can be turned over many times with long service life; finished part will not turn white
  • Non-toxic, odorless and shipped as non-hazardous
  • ROHS & SGS certified; color, hardness, viscosity and operating time adjustable (OEM/ODM)
