How to Solve Color Difference Issues of GRC Decorative Panels? Qinglong GRC Color Difference Control Technology

Color difference issues in GRC decorative panels are solved through three aspects: raw material control, production process standardization, and construction management. Raw material batches have a color difference of ΔE≤1.0, mix ratios and processes are strictly controlled during production, and attention is paid to batch matching during construction. Premium products control color difference at ΔE≤2.0.

Through strict quality control, a large-scale project kept GRC panel color difference ΔE within 1.5, achieving a uniform and consistent overall effect. Qinglong GRC's standard color difference control plan ensures an aesthetic appearance.

Raw Material Control

Pigment batch ΔE≤1.0; these controls guarantee quality at the source.

Production Process Standardization

Precise control of mix ratios; unified process parameters; these standards ensure consistency.

Construction Management Measures

Panels on the same facade installed from the same batch; these measures avoid color differences.

Color Difference Testing Methods

Color difference meters measure ΔE values; these tests provide objective evaluation.

Color difference control requires whole-process management. Qinglong GRC maintains strict control for uniform color.
