Weathering test is an important means of screening formula ａnd optimizing product composition in the process of scientific research ａnd production, ａnd it is also an important content of product quality inspection. Applied materials such as coatings, plastics, aluminum-plastic plate, ａnd automotive safety glass are required to do weathering test.

The main factors causing material aging are sunlight ａnd humidity. The weathering test chamber can simulate the hazards caused by sunlight, rain ａnd dew. The weathering test chamber uses ultraviolet to simulate the effect of sunlight, ａnd uses condensed moisture to simulate rain ａnd dew. The tested materials are placed in the cycle program of alternating light ａnd moisture under a certain temperature for testing, ａnd the outdoor hazards for months or even years can be reproduced in a few days or weeks. Artificial accelerated aging test data can help to ｓelect new materials, modify existing materials, ａnd evaluate how formula changes affect product durability.
