Film Fused to Powder Coating After Curing? Switch to Guangdayuan‘s Heat-Release Aluminum PE Film

Material & Craft

When PE protective film becomes permanently bonded to powder-coated aluminum after curing, the adhesive has chemically cross-linked with the coating — essentially welding the film to the surface. Ordinary films lack heat-release properties. Guangdayuan solves this with thermally reversible adhesive technology. Developed through our partnership with Harbin Institute of Technology, our adhesive maintains bond strength during coating but automatically weakens above 150°C, releasing cleanly after curing.

Performance Features

Unlike ordinary films that fuse permanently, Guangdayuan‘s heat-release film delivers easy peel after every cure. The adhesive transition is fully reversible — strong during processing, weak at removal. No coating damage, no residue, no rework.

Article Summary

Fused film means lost production. Guangdayuan’s heat-release aluminum PE film peels cleanly after every cure. Backed by 20 years of expertise, we offer free sample testing. Contact us at 0755-28171981 or 18928456898 for easy-release powder coating protection.

Product Introduction

Guangdayuan’s heat-release aluminum PE protective film is engineered for powder coating lines. With over 20 years of expertise and premium raw materials from Toray and Toyobo, our film survives the curing oven intact — then peels off easily once cooled. No scraping, no solvents, no damaged coatings.

Product Parameters

Thickness range: 50μm to 120μm. Width: up to 2000mm. Heat release temperature: >150°C. Adhesion after curing (cooled): <10g/in. Maximum oven temperature: 200°C for 30 minutes. The film passes ISO9001 and ISO14001 certification. Produced in our 16,000㎡ automated facility.

Application Range

This heat-release PE film is specifically designed for powder-coated aluminum profiles, electrostatically painted extrusions, and oven-cured metal parts — where protecting uncoated areas during spraying is required, but easy removal afterward is equally critical.
