Lindride^® Anhydride Epoxy Curing Agents

Lindride® Anhydride Epoxy Curing Agents are a family of reactive curing agents designed for epoxy resin systems, providing controlled cure progression together with excellent thermal, electrical and chemical resistance. Through careful selection of anhydride chemistry and catalyst technology, the Lindride range enables formulators to optimise cure speed, processing characteristics and long-term performance across demanding industrial applications.

Lindride products are widely used in composite materials, electrical encapsulation, adhesives, coatings and structural epoxy systems where high mechanical strength, dimensional stability and durability are required.
