Product Description

Transparent RTV2 Tin Cure Liquid Silicone Rubber for Epoxy & Polyester Resin Molds — HN-625 A/B

HN-625 A/B is a transparent two-component RTV2 tin cure (condensation cure) liquid silicone rubber with high chemical stability and a wide temperature range of -55°C to +220°C. Cured at room temperature with a 100:2 mixing ratio, it produces precise, low-shrinkage molds — ideal for epoxy casting, polyester resin molds, and stone / gypsum construction and crafts.

Key Features

  • High chemical stability — performs from -55°C to +220°C for long-term use
  • Transparent appearance — clear formulation allows easy visual monitoring of mold quality
  • Low shrinkage (≤0.2%) — no low-molecule release during cross-linking, high precision
  • Low viscosity and good fluidity — easy pouring; cures at room temperature or with heat
  • High tear strength (19.8–24.3 kN/m) for many demolding cycles and long mold life
  • Waterproof and ozone resistant; non-toxic, tasteless, non-corrosive; MSDS & RoHS certified
