Vinyl Ester Scale Compound Ripoxy™FC-83 NS WHITE EX (Intermediate Coating) Ripoxy™FC-83 S GREY EX (Top Coating) 1. Ripoxy Scale Coating The usual resin coating refers to a fiberglass coating formed by adding resin to glass fibers, typically 1-3 mm thick. in this case, however, the introduction of a scale coating. That is, scale glass is added to a liquid resin, which is mixed with the scale glass to form a slurry mixture (Ripoxy FC). The material can be applied to the substrate using a brush or roller to a thickness of 400-700 μm. scale glass is mixed with the
