2021 Hydraulic Fracturing Technology Showcase

On-the-fly resin coating controls proppant flowback and enhances conductivity. Hexion’s PropCure on-the-fly curable resin coating allows users to coat proppant for hydraulic fracturing on location in the blender tub. The coating is a two-part system that is combined with a simple static mixer on the frac site.
