Plasite 4540

This product is a solvent-free, edge retentive, blush-resistant high performance epoxy coating designed as an internal tank lining for chemical or other commodity storage. It is a two-component system applied by plural component spray equipment, at film thicknesses of 20-50 mils (500-1250 microns) in a monolithic application. It is particularly suited for petroleum-based cargoes including crude oil; fuel oils, gasoline and gasoline blends, jet fuel and diesel. It has excellent hot water resistance (deionized water up to 180°F/82°C). It has extremely fast cure times for turnaround projects that require placing back in service quickly. The product has a unique ability to be applied as a prime coat and immediately back-rolled after spraying. This is recommended to treat pitted steel, weld areas, and the like. A second coat can be applied right after the prime coat using the same product for a “two-coat” yet monolithic application.
