In silico weathering of a coating: a theoretical approach

Controlled exposure is one of the key factors for putting coating systems to the test. With that in view artificial ageing is widely used to collect information on the performance of a coating system, monitoring the change of parameters such as gloss, colour, adhesion, surface roughness, etc. With the fast evolution of computing power and the increased and detailed knowledge on degradation phenomena, in silico weathering of a coating comes within reach. This offers the possibility to predict performance starting from input data from coating and substrate. Obviously this virtual ageing is a simplified version of the standard lab test, yet it can become a powerful tool for early screening of coating systems.
