WHAT IS POWDER COATING “A mechanical mixture of resin, pigments & hardening agents in powdered form, when applied on to a surface as a thin/thick layer, forms an adherent film after curing”. ================= CONSTITUENTS OF POWDER COATING ============================== CONSTITUENTS OF…
How to determine the coating weight of zinc phosphate coating
by Dr E Ramanathan Generally, thickness of different types of phosphate coating is reported as coating weight. Weight per unit surface area of phosphate coatings is calculated as follows: The coated specimen is weighed to the nearest mg (w1); the coating is removed by immersing the coated specimen in a 50 g/L chromic acid stripping…

Sandblasting or phosphating or both?
Do we need phosphating after sand blasting followed by powder top coat on hot rolled steel components? No. It is not necessary if the salt spray resistance required is less than 550 hours. The purpose of sand blasting is to improve the surface profile of the component with a surface free from rust and heavy…
