Who We Are

One team from monomer to topcoat

Based in Songjiang, Shanghai, serving coating-fabric and flexible-material producers at home and abroad

What we make

13 KHAOS® surface treatment agent grades across acrylic, PVDF, water-based, functional and printable series, plus 238 specialty acrylic resin grades in five series — every grade shipped with TDS, MSDS and COA.

How we work

Resin chemistry and topcoat formulation under one roof: monomers sourced through pooled 10,000-tonne purchasing, synthesized and compounded on our own lines, validated on real knife-coating and roll-coating lines.

Compliance ready

Lower-VOC MEK-based systems, batch-level traceability with retained samples, nationwide hazardous-materials logistics and complete export documentation — built for audits and OEM approvals.
