The X-L Products Epoxy Primer Catalyst is a professional-grade hardener designed for use with epoxy primer systems in body shop applications. This catalyst provides reliable curing performance for direct-to-metal priming and substrate preparation across multiple surface types including steel, aluminum, galvanized metal, fiberglass, SMC, plastic, e-coat, and existing primer surfaces.
With an extended 8-hour minimum pot life, this catalyst allows technicians ample working time for larger jobs or multiple panels without rushing application. The system applies in a single coat and delivers 570 g/l VOC content. The versatile substrate compatibility makes it suitable for mixed-panel repairs and eliminates the need for multiple primer systems in most collision repair scenarios.
Proper ventilation and appropriate respiratory protection are required during mixing and application. Follow all manufacturer mixing ratios and application guidelines for optimal performance and adhesion.
