Craymide Epoxy Hardener is a high-performance epoxy hardener commonly used to cure epoxy resins. It is a polyamide-based curing agent that promotes excellent cross-linking with epoxy groups, resulting in coatings, adhesives, and composites with superior mechanical strength, chemical resistance, and durability. This hardener is widely used in industrial coatings, adhesives, and composite manufacturing due to its balanced curing profile and compatibility with a range of epoxy systems. Craymide 115 provides toughness and flexibility while maintaining strong adhesion to various substrates.
