Passivation Chemicals

This is a gel type chemical applied with a brush to descale the heavy weld scales. It removes discolourations, heat marks, annealing colours, rust particles in and around the welding area caused due to heat evolution during welding. "K-2" paste cleans 90-100 metres of weld seams in 1 kg. of chemical. K-2 paste is to be applied on the weld seam & surrounding area with a brush. Leave the K-2 paste on the weld seam for 30-45 minutes depending on the thickness of the oxide scale. Brush the surface with a plastic bristled brush and then wash surface thoroughly with water.
