High Temperature Epoxy Coated Aluminum Sheet

Core Advantages

• Special high-temperature epoxy coating, stable performance under continuous 280℃ high temperature, no bubbling, cracking or peeling

• 3003 aluminum substrate, lightweight yet rigid, won’t rust in high temperature & humid industrial environments

• Integrated epoxy layer achieves excellent resistance against oil, weak acid, alkali and industrial dust erosion

• Compact matte coating surface, easy to wipe oil stains and industrial dirt, convenient daily cleaning

• Coating possesses strong bending flexibility, can be folded, stamped and processed on site without damaging the heat-resistant layer

• Non-flammable aluminum body, A2 fire grade, effectively stop flame spread for industrial safety

• No toxic volatiles under high temperature heating, no harmful gas release, environmentally safe

• Customizable thickness, color and coating thickness to match different temperature working scenarios

Production Process

Aluminum coil feeding → Degreasing & washing → Chromium-free passivation drying → Primer roller coating & curing → High temperature resistant epoxy topcoat coating → High-temperature baking curing → Cooling → Protective film covering → Fixed-size cutting → High-temperature aging sampling test → Coating adhesion inspection → Stacking & moisture-proof export packaging

Each batch undergoes high temperature aging test and salt spray test before delivery to guarantee heat resistance performance.

FAQ

Q1: What is the maximum sustainable working temperature?

A: Standard epoxy coating version works steadily at 220℃ continuously; enhanced high-temperature formula can reach 280℃ long-term usage.

Q2: Will the coating release toxic fumes when heated?

A: Food-grade high-temperature epoxy formula, no VOC volatilization and no toxic gas when heated, safe for oven and food baking equipment shells.

Q3: Can it be bent and processed?

A: Yes, the epoxy coating has good flexibility, conventional bending, cutting and punching construction will not cause coating peeling.

Q4: How long is the service life in high-temperature factory environment?

A: Normally 12~18 years indoors in high-temperature workshops, no fading or peeling.

Q5: Can I customize black high-temperature epoxy color?

A: Supported, black epoxy coated aluminum sheets are commonly used for oven casings, heat equipment outer covers.
