Luna-flex MP25-H is a chlorinated binder that is used for the manufacture of physically drying coatings on iron and steel, non-ferrous metals, mineral substrates as well as road marking paints resistant to hydrolysis. It is a resin based on vinyl chloride and vinyl isobutyl ether copolymer. Luna-flex MP25-H is resistant to hydrolysis, corrosion, and is compatible with a wide range of resins, and can therefore be used to formulate for anti-corrosion coatings, concrete coatings, road marking paints, flame-retardant coatings and marine and container paints.
