How Is the UV Resistance of GRC for Decorative Panels Ensured? Qinglong GRC Weather Resistance Technical Measures

The UV resistance of GRC decorative panels is ensured through dual measures of material modification and surface protection. Low-alkali cement (alkali content ≤0.6%) is used, UV absorbers are added (dosage 0.5%), and a fluorocarbon coating is applied to the surface (thickness ≥35μm). Testing shows UV resistance reaching 3,000 hours with color difference ΔE≤3.0.

Accelerated aging tests show that treated GRC panels maintain ≥90% strength retention after 3,000 hours of UV exposure, with only slight color change. An outdoor decoration project has kept a good appearance after 5 years of use. Qinglong GRC ensures product weather resistance through strict quality control.

Material Modification Technology

Low-alkali cement reduces alkali-aggregate reaction; UV absorbers enhance weather resistance; these modifications improve performance.

Surface Protection Treatment

Fluorocarbon coating thickness ≥35μm; self-cleaning coating reduces staining; these treatments enhance protection.

Process Control Points

Coating is uniform with no missed areas; adequate curing ensures strength; these controls guarantee quality.

Testing and Verification Methods

Xenon lamp aging test for 3,000 hours; these verify reliability.

UV resistance requires systematic assurance. Qinglong GRC's professional technology keeps it looking new for the long term.
