Product Description
SH-720 Organosilicone release agent
I. Performance and Applications
This product is a solid-containing formulation. 30% This is a primary component of silicone release agents, classified as an addition‑cure, solvent‑based silicone release agent with toluene as the solvent. It cures rapidly upon heating and exhibits stable release performance, excellent adhesion to substrates, and good bath stability. The product delivers low release force, produces a smooth coating, offers broad applicability, and maintains a relatively high residual tack. It is suitable for siliconizing most conventional release papers and release films and demonstrates good compatibility with a wide range of adhesives. Applications include adhesive tapes, labels, single‑sided and double‑sided industrial release papers and films, and anti‑stick packaging, among others.
