High Elongation Liquid Silicone Rubber For Flexible Mold Making And Repeated Casting

This short presentation tells the story behind the design and intended use cases of HN-620 A/B condensation cure liquid silicone rubber. Watch as we demonstrate its exceptional 600-720% elongation and high tear strength for creating durable, reusable molds in large-scale architectural projects like stone replicas, Roman columns, and decorative elements. Learn about its room-temperature curing process, self-de-airing properties, and how its ultra-low shrinkage ensures dimensional accuracy in professional mold-making applications.
