ERICW LLQ Toughening Agent

The ERICW LLQ series high-performance toughening agents designed for epoxy, thermoplastic, and thermosetting resin systems. Utilizing anhydride modification and functionalized polymer architectures, these modifiers enhance mechanical resilience, impact resistance, and stress dispersion while retaining thermal stability (up to 200°C+) and chemical resistance. Their low-viscosity formulations ensure seamless integration into matrices, optimizing processing efficiency in composites, adhesives, and coatings.

Ideal the series delivers tailored flexibility for applications such as automotive components, electronic encapsulants, and industrial coatings, where crack resistance and low-temperature durability are critical. Compatible with resins like polyurethane, nylon, and phenolic systems.
