Product Description
SH-710 Silicone release agent
I. Performance and Applications
This product is a solid-containing formulation. 30% The main component of this silicone release agent is a addition‑cure, solvent‑based silicone type, with toluene as the solvent. It cures rapidly upon heating and exhibits stable release performance, excellent adhesion to substrates, and good bath stability. This product delivers low release force and produces a smooth coating. It is primarily used for silicone coating on laminated paper but can also be applied to certain… PE Membranes, such as the base membrane of waterproofing sheets or silicone-coated silent tapes, are not suitable. PET Silicone coating. Used for pressure-sensitive adhesive tapes, release liners for labels, single- and double-sided industrial release papers, and anti-adhesive packaging, among other applications.

SH-710 Silicone Release Coating
Ⅰ. Product Description
SH-710 is a solvent-based, addition-cure silicone release coating base with a 30% solid content, using toluene as the solvent. It features rapid thermal curing, stable peel force, good adhesion to substrates and excellent bath stability. It has low peel force and provides smooth coatings. It is mainly used for silicone coating on coated paper, or certain PE films like waterproofing sheet membrane and silent tapes while not on PET films. Applications include r elease papers for pressure-sensitive adhesive tapes (PSA) and labels , s ingle-sided and double-sided industrial release papers , and n on-stick packaging .
