FAQ

Surface Treatment Agent FAQ

What is a PVC surface treatment agent?

A functional coating applied to the surface of flexible substrates such as PVC calendered film, synthetic leather and tarpaulin. It provides easy-clean, abrasion-resistant, anti-static, weatherable and printable surface performance, and improves downstream printing and welding processes.

Which KHAOS® series and grades are available?

Five series, 13 grades: acrylic (32193 / 32133 / 37203 / 2537), PVDF (96366 / 96369), water-based (W33908 / W33906 / W33903), functional (K193 / P-903) and printable (3557 / 32191+).

What is KHAOS®'s market position?

KHAOS® holds over 50% of the domestic PVC surface treatment market and is the common choice for knife-coated fabric, tarpaulin, membrane and printable-media production lines, selected by major coating and lamination producers for its lower volatile content.

What are the advantages of the MEK-based system?

The MEK (butanone) system has lower volatile content and fast drying, with good compatibility with downstream high-frequency welding and embossing — balancing surface performance with workshop environment.

Do you support sampling?

Yes, 1–5 kg samples. The process window is confirmed against your substrate and application method (knife-coating / roll coating / gravure roller) before volume supply. Contact qileilei@yaochengroup.com or +86 18621528861.
