Functions at temperature range of: 65 to 70 deg. C. In about 3 to 5 minutes' of dip duration, forms velvet-smooth, dense, very hard and crystalline calcium modified zinc phosphate coating. The Coating wt: between 250 and 400 mg/s.ft. It is an Ideal base for subsequent painting liquid paint, powder coating,
The Calcium present acts as the in-built grain refiner in the phosphating bath and hence eliminates the need for a separate activation or a titanium pre-rinse step. Thus, the introduction of calcium not only results in the formation of coatings of good quality, but also contributes to the economy of the process through the elimination of the pre-rinse process stage.
