General Introduction – Matting Approaches
The term “matting“ describes the general property of a surface to scatter incoming light. As a result of the non directed reflectivity, the surface looks matte.

General Introduction – Matting Approaches
4
The classic approach• Particle related matting effect• The matting effect appears on the surface of the coating and is mainly related to a
rough and uneven surface structure

General Introduction – Matting Approaches
5
Internal light scattering• Matting effect mainly related to crystal structures• The matting effect appears inside the coating film. Incoming light will be scattered by
crystalline structures inside the coating film. (Crystals can be generated by controlled precipitation while curing.)

General Introduction – Matting Approaches
6
Controlled surface structuring• Related to special curing phenomenon. • The matting effect appears only on the coatings surface and is related to a fine
microstructure. (Structures can be generated by Excimer curing or via special additives.)
