Elasticity is the property to resist a distorting influence and to return to its original size and shape when that influence or force is removed.
Coating is influenced by external factors such as stress, bending or impact, to determine suitability for their designed application.
While deformation or damage can reduce the protective quality and appearance of the coating including colour change, adhesion, gloss, etc.
A coating designed for industrial use should be able to withstand an acceptable level of impact during the life of the product.
