Twin Pack Epoxies, in general, have better solvent and chemical resistance than the Twin Pack Polyurethanes. They have better adhesion to metals, and again, in general, have better abrasion resistance than Twin Pack Polyurethanes. They are also cheaper than their Polyurethane counterparts. Their chief draw-back when compared to TP Polyurethanes is their very poor u.v. resistance - making them suitable only for interior coating applications.
Twin Pack Polyurethanes can be used for demanding out-door applications such as the coating of boats, trailers, automotive coatings, aircraft, trains etc.
Both options have similar surface preparation and curing requirements, and both require a level of expertise to use. Always check with the supplier before using these products as to their suitability for your requirements, and obtain a detailed specification for the application. When used correctly, both products can provide many years of protection.
