Surface Finish Options Overview
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.
