Siemtcoat® SF211 Solventless Light Release Coating

Zero VOC • Stable Release • Low-temperature Fast Curing

HANGZHOU, China – Topwin (a subsidiary of Wynca Group) proudly introduces Siemtcoat® SF211 Solventless Light Release Coating, a premium 100% solids release coating designed to overcome common weaknesses of traditional solvent-based release agents, including high VOC emissions, unstable release force, adhesive residue, and silicone transfer. Ideal for label printing, tape manufacturing, medical care, food packaging, electronics, and new energy applications, Siemtcoat® SF211 enables green, high-speed, precision-driven mass production with consistent high quality.

Core Advantages

• 100% Solids & Zero VOC: Solventless, odorless, non-flammable, and fully RoHS/REACH compliant. Safe for food, medical, and pharmaceutical use, supporting clean, eco-friendly production and easy regulatory approval.
• Precise & Stable Light Release: Delivers a consistent 3–5g/inch release force with minimal batch variation. Provides smooth peeling, no residue, no silicone transfer, and high residual adhesion to preserve original tape performance.
• Low-Temperature Fast Curing: Fast curing at low temperatures protects heat-sensitive films and substrates while supporting high-speed die-cutting, rewinding, and slitting for industrial mass production.
• Dense & Durable Coating: Forms a smooth, pinhole-free, uniform coating with strong substrate adhesion, excellent weather resistance, and long-term performance stability.

Key Applications

• Label Printing: Widely used for self-adhesive, thermal, food, pharmaceutical, logistics anti-counterfeit, and cosmetic labels. Compatible with glassine paper, synthetic paper, and art paper; enables high-speed coating and die-cutting with no paper tearing, no glue damage, and higher yield. Its solventless eco-friendly property is ideal for food, medical, and other strict scenarios, ensuring full regulatory compliance.
• Tape Manufacturing: Perfect for double-sided, foam, removable microsphere, and protective film tapes. Ultra-light release prevents substrate tearing or deformation; zero silicone transfer and no residue eliminate contamination and adhesion loss. Ideal for high-end tapes used in temporary fixing, automotive interiors, and home appliance assembly.
• Medical & Hygiene: Medical-grade safe, non-toxic and non-irritating. Applied in medical dressings, band-aids, electrode pads, medical tape backings, sanitary napkins and diapers. Gentle peeling, residue-free and safe for skin-contact products.
• Food Packaging & Office Stationery: Food-safe formulation ideal for baking paper, release liners, and composite packaging with reliable heat resistance and no harmful migration. For sticky notes and envelope seals, it offers smooth, repeatable peeling without paper damage or writing interference.
