Product Description

RTV2 Tin Cure Liquid Silicone Rubber with Technical Data Sheet — HN-620/630 A/B

HN-620/630 A/B is a two-component condensation-cure (tin cure) liquid silicone rubber mixed at 100:2 and cured at room temperature. Made from hydroxyl-terminated polysiloxane, fillers, crosslinker and vulcanization accelerator, it offers good adsorption, 20–40 Shore A hardness options and translucent appearance — an economical industrial-grade mold compound for the building-materials industry (plaster and cement molds) and medium-to-large handicraft reproduction.

Key Features

  • Good adsorption to master models for accurate, bubble-free mold surfaces
  • 20–40 Shore A hardness options to match different mold requirements
  • Translucent / white appearance for easy visual monitoring during pouring
  • High tear strength and elongation; reusable for many mold-flipping cycles
  • Low linear shrinkage (≤0.2%); good fluidity and easy demolding
  • Non-toxic, low odor; full technical data sheet (TDS) and MSDS available on request
