Siemtcoat® SF190MR Solventless High-Speed Silicone Release Coating
Premium Domestic Silicone Release Solution for Ultra-High-Speed Coating Lines
Wynca Group subsidiary Hangzhou Topwin launches Siemtcoat® SF190MR, a three-component solventless silicone release coating engineered exclusively for ultra-high-speed coating on glassine paper, PEK, CCK and coated release papers.
As global coating manufacturers upgrade production lines to operate at over 800 m/min ultra-high speeds, conventional solventless silicone release coatings suffer from persistent production drawbacks: severe silicone misting under high shear, short bath service life, poor substrate adhesion, obvious release force drift after long-term storage, and tiny silicone migration that contaminates pressure-sensitive adhesives (PSA). To solve these widespread industry pain points, our professional silicone R&D team developed the integrated 3-component Siemtcoat® SF190MR silicone release coating — no major refitting of your existing coating equipment is required.
Core Benefits of Siemtcoat® SF190MR High-Speed Solvent-Free Silicone Release Coating
Modified rheology design optimizes fluid flow during coating, effectively suppressing silicone mist generation and white spot defects. This solventless silicone release coating cuts floating airborne silicone particles, delivers uniform coating surfaces, stabilizes 800+m/min high-speed production, reduces reject rates and boosts overall factory productivity.
Dense and uniform crosslinking structure locks consistent release force for both fresh and aged release liner rolls. After 6–12 months of long-term storage, the peel force only rises marginally. Residual adhesion rate exceeds 92%, with zero silicone transfer and no adhesive residue left on PSA. It avoids common issues including liner sticking and premature label shedding, perfectly sustaining the original adhesive performance of acrylic and rubber PSA tapes.
The formula strictly limits free small cyclic silicones D3/D4 and adopts high-strength substrate anchoring technology. Even under heavy stacking or long-time high-temperature storage, it prevents oil stains, surface whitening and silicone bleed. This high-purity silicone release coating fits precision electronics die-cutting, high-end cosmetic labels and other strict cleanliness applications.
Zero VOC discharge eliminates fire risks, fully meeting global green factory standards and EU & US environmental export compliance requirements. It forms strong bonding with glassine, PEK and CCK base paper, effectively resisting silicon shedding, film delamination and pinhole defects. Widely applicable to self-adhesive labels, industrial double-sided tapes, protective films and medical release liners.
Separate crosslinker and catalyst design avoids premature curing during storage and mixing, with adjustable mixing ratios for simple on-site operation. Supported by Wynca’s full vertical silicone raw material supply chain, we customize silicone release coating formulas matching your actual line speed, base substrate and target release force. We also provide full one-stop coating technical solutions and on-site process debugging services.
Industry Recognition & Cost-Effective Import Substitute
Our full series of high-speed solventless silicone release coatings won wide recognition from top global coating factories at the 2025 Asia Label Expo held in Shanghai. Filling the market gap for high-performance domestic ultra-high-speed silicone release coating, Siemtcoat® SF190MR acts as a stable, cost-saving alternative to imported silicone release agents.
If you are troubled by high-speed misting, unstable long-term peel force or massive waste caused by silicone migration, feel free to contact our technical team. We offer free laboratory testing and customized full technical support for your release coating production line.
