Introduction

Dark Gray Powder Coating

Our Dark Gray Powder Coating belongs to the epoxy-polyester resin (hybrid) series, combining the adhesion of epoxy with the weather-stable appearance of polyester. Designed for indoor applications, it delivers a smooth, uniform dark gray finish with strong film build, excellent insulation and reliable corrosion protection. The coating is easy to apply by electrostatic spray and cures efficiently at low temperature, making it a cost-effective choice for household appliances, metal furniture and daily-use hardware.

Key Features

Strong Adhesion

Forms a tight bond with pretreated metal, resisting chipping and peeling in everyday use.

Excellent Mechanical Strength

A tough, resilient film withstands impact, bending and surface abrasion.

Reliable Insulation

Good dielectric performance makes it suitable for electrical appliance housings.

Effective Corrosion Resistance

Protects indoor metal parts against rust and humid environments.

Energy-Efficient Curing

Cures at 190℃ for 15 min, lowering energy use versus high-bake systems.

Easy Application

Smooth electrostatic spray with convenient operation and high first-pass transfer.

Application Areas

Home Appliances

Air conditioner indoor units, fans, radiators, kettles, refrigerators, TVs, kitchen hoods, disinfection cabinets, rice cookers.

Kitchenware & Tableware

Knives, forks and other daily metalware that need a durable, food-area-safe finish.

Lighting & Electronics

Lighting fixtures and electronic enclosures requiring insulation and a clean look.

Indoor Furniture

Tables, chairs, cupboards, safes, wrought-iron beds, doors and curtain rods.

Decorative Crafts

Ornaments and handicrafts that call for a uniform, matte dark gray surface.

General Indoor Metal

Any indoor metal part needing durable protection with an attractive finish.
