Evercoat 4:1 Catalyst 32 fl oz — epoxy-enriched polyester primer catalyst for easier mixing and consistent cures

Evercoat 4:1 Catalyst is a 32 fl oz epoxy-enriched polyester primer catalyst formulated to deliver consistent, easy-to-mix activation for Evercoat 4:1 polyester primer surfacers.

Designed for collision repair pros and advanced DIYers, this patented catalyst improves the workability and performance of Evercoat’s 4:1 polyester primer surfacers. It simplifies the mixing process compared with traditional polyester catalysts, promotes a more uniform cure, and is engineered to perform well in cooler conditions. Evercoat’s long history in automotive primers and fillers underpins this formula, which supports efficient bodywork and refinishing workflows.

How does this catalyst change the mixing process?

Using a 4:1 catalyst ratio reduces the number of measuring steps and lowers the chance of mixing errors. The epoxy enrichment helps the catalyst incorporate evenly into Evercoat’s 4:1 primer surfacers, producing a consistent working time and cure profile across the batch.

• Simpler 4:1 mixing ratio for fewer measuring steps
• Improved dispersion thanks to epoxy-enrichment
• Predictable pot life and tack-free time for workflow planning

What surfaces and conditions is it suited for?

Evercoat’s 4:1 Catalyst is formulated for use with Evercoat 4:1 polyester primer surfacers on typical automotive substrates including steel, aluminum, and properly prepared plastics. The formula performs reliably in cooler shop temperatures, making it a versatile option across a range of repair environments.

• Compatible with steel, aluminum and prepared plastic panels
• Patented formulation optimized for cooler temperatures
• Works specifically with Evercoat 4:1 polyester primer surfacers

What safety and compliance points should I know?
