Emerald Paint–Prep 389 NP is a phosphate–free cleaner coater with no regulated heavy
metals. It is designed to provide an effective cleaning and a conversion coating that can
be applied successfully at temperatures ranging from 80掳贵 to 110掳贵 in spray wand
applications. Emerald Paint–Prep 389 NP provides a microcrystalline surface in the
nanometer (10–9m) while conventional iron phosphate coatings are usually in the
micrometer (10–6m) range. These 鈥渘anocrystals鈥� increase the surface area of the
substrate thus enhancing paint adhesion, corrosion protection and consequently salt–
spray results.
