SUNOIT™ Silicone Release Agents: Efficient Isolation, Clean Release

Silicone release agents are functional coating materials applied to substrates such as paper, film, or fabric. Their primary function is to form a uniform, stable release layer between the adhesive and the substrate, enabling pressure-sensitive adhesives and sticky substances to release cleanly and effortlessly without residue or damage to the adhesive surface.

The unique Si-O-Si backbone of silicone molecules imparts extremely low surface tension and chemical inertness to the release coating. Once cured, it forms a dense isolating film that most adhesives cannot effectively bond to. Combined with excellent thermal stability and flexibility, silicone release agents maintain consistent performance through high-speed coating, high-temperature drying, and long-term storage.

SUNOIT offers a complete range of solventless, solvent-based, and emulsion-type silicone release agents, covering precise control from ultra-light to heavy release levels. Our products are widely used in label stock, adhesive tapes, hygiene products, express envelopes, baking papers, and industrial release films. Solventless systems lead the industry trend with zero VOC and high coating efficiency; emulsion types use water as the carrier for eco-friendly processing; solvent-based grades suit fast-cure processes. With consistent quality and flexible customization, SUNOIT delivers compliant, high-efficiency release coating solutions for the packaging, labeling, hygiene, and industrial sectors.
