powder Coating

Food grade powder coatings are specially formulated solvent-free, non-toxic coatings that meet FDA and EU food contact regulations. They are designed for direct or indirect contact with food, providing a safe, durable, and aesthetically pleasing finish. These coatings are ideal for kitchen appliances, food processing equipment, and public food facilities.

Applications & Use Cases

Industry	Typical Products/Parts	Benefits of Food Grade Powder Coatings
Kitchen Appliances	Ovens, mixers, toasters, cookware	Non-toxic, heat-resistant, easy to clean
Food Processing Equipment	Conveyor belts, storage bins, stainless steel trays	Hygienic, corrosion-resistant, FDA compliant
Beverage & Dairy Industry	Milk tanks, beverage dispensers	Safe for direct contact with liquids, durable finish
Furniture & Public Use	Cafeteria tables, metal shelves	Anti-bacterial, easy to maintain, long-lasting
Packaging & Containers	Metal cans, food storage containers	Protective coating, prevents contamination

Key Advantages

Food Safety Compliance – Meets food contact standards.

Durable & Hygienic – Resistant to corrosion, scratches, and cleaning chemicals.

Eco-Friendly – 100% solvent-free, low VOC, safe for food applications.

Wide Range of Colors & Gloss – Attractive and consistent surface finish.

Industrial B2B Supply – Suitable for OEM production and large-scale applications.

Health and safety

Operators should wear dust masks during use to avoid inhaling dust, and minimize long-term contact between skin and powder coating. Paint attached to the skin can be washed with soap.
