Scratch / Scrub / Mar Resistance Agents

Scratch, scrub, and mar resistance agents are used to improve the surface durability of a cured coating film, making it less susceptible to damage from abrasive contact, cleaning, or everyday wear. Key features include increased surface hardness, reduced coefficient of friction, and improved slip properties. They are highly suitable for high-traffic floor coatings, automotive clearcoats, furniture finishes, and decorative paints, where preserving the aesthetic appearance and integrity of the coating under abrasive conditions is paramount. 

A trend is the development of highly efficient, transparent scratch/scrub/mar resistance agents that do not negatively impact gloss or clarity, and which are compatible with a wider range of coating chemistries. Sub-types include various types of waxes (e.g., polyethylene, PTFE), fine inorganic particles (e.g., silica, alumina), and specialized polymer additives, each contributing different mechanisms of protection.
