Mar / Scratch Resistance

High-quality paint is expected to keep great appearance and to provide substrate protection for a long period of time.

To achieve this requirement, coatings need to be scratch and mar resistant as the film surface will have to face light abrasion, impact or pressure during its service life.

The primary function of mar/scratch-resistant additives is to help maintain the original appearance of the coating by reducing physical damage. In practical terms, a scratch is the first visible sign of damage.

Unlike abrasion, this property is independent of hardness. Therefore surface modifying additives help to improve this resistance by acting as lubricate agents.

The incorporation of wax in the coating formulation brings a beneficial effect on mar and scratch resistance. Indeed, wax will migrate to the film surface and thus play its protective effect.
