25. Epoxy vs. Polyaspartic ? Web Search this question? You will find thousands of comments and opinions… Every product or resin technology has advantages and limitations… No single product or technology is best for every application. Example: chemical & stain resistance varies widely by specific formulation; not just the type of generic resin in the product… A full line, full service manufacturer will take the time to know a client’s specific requirements then recommend the best solution
