Accelerated weathering for the testing of binders

The performance properties of coatings are predominantly governed by the binder material. Weathering is the most important and conclusive method of testing binders. Although valuable information is obtained from mechanical tests determining hardness, adhesion strength, flexibility, abrasion resistance, etc, they offer no direct relationship between the measuring data and the performance of the systems. It is only in special cases that electrical properties and, in particular, chemical resistance levels are of any interest.
