CrysCoat LWT is an internally-accelerat
ed, robust, simple-to-use, zinc phosphate, applied by spray, primarily for steel, prior to painting. Small-to-moderate amounts of hot dip galvanized steel, galvanneal, electrogalvanized steel and aluminum may also be processed through CrysCoat LWT, although coatings are normally developed on aluminum only with special additives. Because there is no nitrite accelerator to add to the bath, the amount of sludge is reduced. The dense, fine-grained zinc phosphate coatings produced by CrysCoat LWT improve the performance of electrophoretic, powder, solvent-borne and water-borne paints. CrysCoat LWT meets the requirements of Federal Specification TT-C-490 Type 1. Coating weights of about 150-500 mg/ft2 (1.5-5.0 g/m2) can be produced with CrysCoat LWT, depending on the parameters and on the particular grain-refining activator used in the rinse prior to CrysCoat LWT.
