Technical Write up by Dr E Ramanathan Powder coating Training Notes WHY POWDER COAT ? 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…
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…
