Description
HY0S wheel matt primer is an epoxy/polyester hybrid powder coating for aluminium wheel basecoat and decorative protection. It is positioned for high flow, filling and hiding performance, paint compatibility and powder penetration into bolt cavities. Used with colour paint and acrylic high-gloss clear powder, it supports wheel appearance and long-term protection. The curing temperature can be reduced to 150°C for automotive OEM coating requirements.
