Epoxy Resin is a generic term used for a wide range of resins or the composite polymer part compound of epoxy and resins. Epoxy refers to either a specific compound or composite compound, or a slang term for the common epoxy resin functional group of resins. Epoxy resins are a family of resins and polymers that contain epoxies. Epoxy resin can be created from different sources and are commonly produced by reacting a mixture of the resins with water.
Polyurethane Resins (or polyurethane polymers) are the most widely used types of resins today and are found in many different applications. The polyurethane polymer resin is widely used in the automotive industry because of its high level of resistance to extreme temperatures, heat, and moisture, and it has excellent chemical and structural properties. However, polyurethane polymers also have some disadvantages and are limited to industrial use, which makes them unsuitable for industrial and commercial applications.Have a look at Canada Epoxy Resin for more info on this.
Industrial polyurethane polymers are found commonly in paints, coatings, sealants, and other industrial products. Industrial polyurethane polymers are usually mixed with a solvent and then added to an industrial-grade polyurethane liquid and injected into a mold. These polyurethane resin mixtures can be used in numerous applications and can even be incorporated into industrial products.
