Which is better, unsaturated resin or epoxy resin?
Which is better, unsaturated resin or epoxy resin?This question is a bit difficult to answer directly. Any product will have advantages and disadvantages, and choosing the right one is the best. A simple performance comparison between unsaturated resin and epoxy resin is expected to be helpful for beginners:

Generally speaking, most cases of processing fiberglass components or general waterproofing and sealing are mostly based on economical unsaturated resins, which have a fast curing cycle and significantly greater economic benefits. However, some high-performance composite components, such as carbon fiber products or aviation shells, are still dominated by epoxy resin systems, and there are also some engineering projects with high anti-corrosion requirements, mainly based on epoxy or epoxy vinyl resin.
Obviously, the overall benefits of using unsaturated resin for epoxy resin components are much greater than those of epoxy resin, but everything is based on ensuring that the performance meets the requirements.
