Corrosion protection coating service Noraplate

wear-resistantprotectiveabrasion-resistant

Product overview
Noraplate is a high-gloss black paint film designed for decorative automotive trims laminated on stainless steel or aluminium. It delivers a deep, glossy appearance while withstanding thermoforming and common automotive cleaning agents. The construction provides long-term UV resistance, mechanical durability and chemical resistance required for exterior and interior trim applications.
