Description
RTV2 Condensation Cure Liquid Silicone Rubber
Product Overview

HN-620 A/B is an industrial-grade, two-part condensation cure liquid silicone rubber system with a standard mixing ratio of 100:2 by weight. This RTV (Room Temperature Vulcanizing) silicone rubber features strong fluidity and high temperature resistance, making it ideal for plaster casting molds and various industrial applications.

Primary Applications
  • Mold making and replication of large stone pieces, gypsum & cement components
  • Cultural stone, artificial stone, Roman columns, and stone carvings
  • Architectural and decorative materials production
  • Split molds for resin crafts, gypsum artworks, and handmade soap
  • Tire casting molds and other industrial applications

Key Features
  • Strong tear resistance with excellent high and low temperature performance
  • Acid and alkali resistance with superior aging resistance
  • Excellent fluidity for easy release and demolding without white residue
  • Long service life with high frequency mold turnover capability
  • Minimal linear shrinkage rate (less than 0.2%)
  • Customizable color, hardness, viscosity, and operating time available
Application Instructions
  1. Thoroughly shake Part B curing agent before use. Weigh Parts A and B at 100:2 ratio and mix uniformly, ensuring complete blending by scraping container sides and bottom.
  2. Vacuum deaerate the blended compound for no more than 10 minutes to avoid over-extended vacuuming.
  3. Allow full room-temperature curing for approximately 4 hours. Heating is not required, but if thermal acceleration is needed, maintain temperature below 100°C.
  4. For optimal mold performance, allow a full 24-hour post-curing rest before demolding or application.
