MIR-120 High Flex is a tough and versatile resin system designed for a single-pour casting or molding of complex parts that require high flexion.

The 120 High Flex is ideal casting, displacement, or injection molding without the need for reinforcement or post curing and allows for the use of low cost tooling applications of detailed and complex finished products.

Formulated using Mirteq’s patented microfiber infusion technology utilizing a high-quality elastomer-modified vinyl ester resin, the MIR-120 provides superior corrosion, chemical, and moisture resistance making it ideal for parts to be used in harsh and high-stress environments and extended life-cycles.

MIR-120 is a two-part system with adjustable working and gel times, viscosity, as well as, color matching. The 120 High Flex is available in 5-gallon pails and 55-gallon drum.
