Tired of unstable release force, high silicone transfer and poor residual adhesion in your heavy‑duty release liner manufacturing?

Hangzhou Topwin launches Siemtcoat® HRA‑11F Heavy‑Release Additive , specially developed for addition‑curable silicone release systems.

With low dosage loading, it delivers stable heavy release performance, minimizes peeling-speed dependency and maintains high residual adhesion. It prevents curing interference, surface hazing and silicone bleed-out, and is compatible with PET film, glassine paper, metallized substrates and existing high-speed coating lines, requiring no equipment modification.

✅ Low dosage & wide formulation tuning window

✅ Consistent release force after thermal aging & long‑term storage

✅ High residual adhesion, negligible silicone transfer

✅ Broad substrate & formulation compatibility

✅ Process‑friendly for existing mass‑production lines

Ideal for high-bond tape, foam tape, double-sided tape, die-cutting and industrial protective film applications.

Sample testing is available. We offer compatibility evaluation with your existing silicone release base agent to speed up your medium-heavy & extra-heavy release film development.
