Resin gypsum actually does not contain resin. Its main component is gypsum powder, which we have newly developed through many years of hard work. It has a hard texture and high smoothness. A friend who makes resin crafts came to me. It is said that this product has no odor and can replace unsaturated resin, but it cannot completely replace it. It depends on what you use it for. Maybe you can order a sample to try.
