Siemtcoat®HRA-11F Heavy-Release Additive – Engineered for Performance, Built for Scale
Heavy-duty silicone release liner production often faces common challenges: unstable release force, silicone transfer, and compromised residual adhesion.
Hangzhou Topwin introduces Siemtcoat® HRA-11F, a high-performance additive formulated for addition-curable silicone release systems. It addresses these core issues at the source, delivering low-dosage efficiency and stable, repeatable results.
Why Siemtcoat® HRA-11F stands out:
→ Low dosage, high efficiency – Only a minimal addition is required to reach target heavy-release levels, with a wide tuning window for precise control.
→ Uncompromising stability – Maintains consistent release force across both low and high peeling speeds, with minimal performance drift after thermal aging and long-term storage.
→ High residual adhesion – Minimal silicone transfer, ensuring reliable performance for downstream processes such as die-cutting and repeated converting operations.
→ Broad compatibility – Works seamlessly with solvent-free silicone release agents, and supports substrates including PET films, glassine paper, PEK paper, and metallized materials.
→ Production-ready – Can be directly mixed into coating solutions, requiring no pretreatment or production line modification.
Ideal for: high-bond tapes, foam tapes, double-sided tapes, die-cutting materials, and industrial protective films.
Samples are available, and we offer compatibility assessments for your existing silicone release base agents to accelerate your heavy-release film development.
