Full Spectrum Simulation, Realistic Illumination

Xenon lamp light source accurately reproduces the full spectrum of sunlight (UV, visible light, infrared), simulating the long-term effects of natural sunlight on coatings, especially for UV-induced fading, degradation and other issues, test results closer to the real outdoor environment.

Accelerated aging and shorter test cycles

Through high-intensity irradiation (e.g. 340nm band), high temperature (blackboard temperature up to 90℃), humidity cycle (30%~95%) and spraying simulation, the natural aging effect of several years can be reproduced in a few weeks, quickly exposing defects such as cracking and chalking of the coating to meet the requirements of ISO 11341, ASTM G155 and other standards.

Quantify color and gloss changes

Accurately controlled irradiance (0.3~120 W/m²) and spectral filtering technology quantify the color difference (ΔE value) and gloss loss of the coating after exposure, providing data support for formulation optimization and ensuring the long-term aesthetics of the product.

Multi-scenario application, covering industry needs

Automotive coatings: Test clear coatings for UV aging resistance and corrosion resistance of metallic paints, complying with VDA 621-430 and other automotive standards.

Architectural Coatings: Evaluate the anti-peeling performance of exterior coatings under humidity cycles to extend outdoor service life.

Industrial protective paints: Verify mechanical strength and weathering resistance to ensure long-term rust and corrosion prevention.

Comprehensive beyond UV weathering testing

Compared with UV tests that only simulate ultraviolet light, xenon test chambers integrate light, temperature and humidity, and rain cycles to reproduce the synergistic effects of multiple factors such as thermal shock and mechanical stress, making them particularly suitable for coatings evaluations in which color stability is a core indicator.

Standardization and Intelligent Upgrade

It supports global standards such as GB 1865 and AATCC 16.3, and is equipped with touch screen, automatic calibration, real-time data tracking, etc. It is suitable for horizontal/vertical sample installation, which improves testing efficiency and reliability of results.

Conclusion: “Accelerator” for R&D and QC

Xenon lamp aging tester with scientific environment simulation and accelerated aging ability, to help coatings companies to shorten the R & D cycle, reduce the risk of outdoor failure, and become a key guarantee of product durability certification and market competitiveness.
