Accuracy of the weathering of paints containing titanium dioxide pigments-A critical retrospective on 20 years of weathering

摘要

Decisions we make today depend on our expectations for the future.This also applies to the selling or purchasing of paints for coatings.If we knew that the good properties of the material would only last for a few months,we would never buy it,nor could we sell it.We therefore require a reliable method to assess the durability of coatings.The worldwide way of doing this is to test the materials in devices for accelerated weathering.
