What separates urethane paints from other types of automotive paints?

Urethane paints are distinct from other types of automotive paints primarily because they require a catalyst for curing. This catalyst, often a hardener or activator, initiates a chemical reaction that causes the paint to harden and adhere better to surfaces. This curing process generally results in a durable, flexible finish that is resistant to chemicals, UV damage, and abrasion.

The necessity of a catalyst sets urethane paints apart from many other paint types, which may dry or cure through evaporation or oxidation without the complex chemical interaction that urethane requires. This enhanced durability is one of the reasons automotive professionals often choose urethane paints for high-performance applications, despite the additional steps and safety measures needed during mixing and application.
