Condensation Cure Liquid Silicone Rubber For Large Scale Architectural Mold Projects
Description of Tin Cure Silicone Rubber
HN-620 A/B is a two-component liquid silicone material. To use, mix the two components in a 100:2 ratio. This product cures at room temperature.
Application of Tin Cure Silicone Rubber
HN-620 A/B is an industrial-grade liquid silicone rubber designed for construction mold manufacturing. It is ideal for the molding and replication of large-scale stones, gypsum, cement components, cultural and artificial stones, Roman columns, stone carvings, furniture, and various architectural decorations. Additionally, it is suitable for resin and gypsum handicrafts, handmade soaps, tire molding, and other segmented mold applications.
