Self-adhesive Liquid Silicone Rubber For PA – Newsil — Silicone Rubber & Foam Manufacturer

This self-adhesive Liquid Silicone Rubber (LSR) is a two-component, semi-transparent silicone designed for strong adhesion to PA substrates. It bonds effectively to glass surfaces while easily releasing from metal molds. The LSR is simple to dye and offers excellent mold release properties, making it ideal for applications requiring secure bonding to PA materials.
