CROMAX Hardener

Cromax Hardeners: Performance, Strength, and Efficiency

Cromax hardeners play an essential role in automotive paint systems. They work through the chemical transformation of resin, forming a solid, cross-linked structure that ensures strength and durability. When used with paint, clear coat, or primer, they provide even curing, reinforce body protection, and improve the overall longevity of the coating.

Types of Cromax Hardeners

Cromax offers a complete range of hardeners, available in 1L and 5L containers, suitable for every application:

• Fast hardener: ideal for localized touch-ups or small surfaces

• Standard hardener: suited for general applications, offering the best balance between drying time and thickness

• Slow hardener: recommended for large surfaces or high-temperature conditions

The range also includes:

• Drying accelerators such as 431R

• Cromax activators, available in fast, standard, and slow versions:

  • XK203: fast hardener

  • XK205: standard hardener

  • XK206: slow hardener

These products are formulated to work perfectly with Cromax clear coats and primers, including the 3800S clear coats and LE2001, LE2004, and LE2007 primers.

How to Choose the Right Cromax Hardener

The choice of hardener depends on several factors:

• The type of substrate: metal, plastic, primed, or previously painted

• The porosity and depth of the surface

• The type of coating used (clear coat, primer, or basecoat)

• The desired drying speed and environmental conditions

If you’re unsure, ColorBox experts are available to help you choose the most suitable hardener for your technical needs.
