Top Coat Silicone for Synthetic Leather Coating 1460B-8

Product Overview

1460B-8 is a smooth-touch top coat silicone designed for synthetic leather finishing. It delivers a silky and skin-like hand feel, provides anti-soiling performance, and helps improve surface comfort. It can be applied directly onto matte/gloss release papers; after curing, the surface becomes smooth and can replace certain surface-treatment effects.
