VC AR306 INTRODUCTION : VC AR306 is a powder based activator which is used at low concentrations prior to zinc phosphating. By dipping the parts in VC AR306 bath prior to phosphating, it accelerates the subsequent phosphating process and also refines the structure of the zinc phosphate coating resulting in smooth fine uniform compact coating. PROPERTIES : Colour : White Form : Free flowing powder PH of 0.2-0.3% : 8-9 APPLICATION : VC AR306 bath can be prepared in M.S. or plastic tank/container. It is to be used at 0.2% to 0.3% concentration with water, at room temperature for one minute. The bath should always be kept in a slightly agitated condition by mechanical means or by passing compressed air from the bottom of the tank to avoid settling of the activator at the bottom of the tank. MAINTENANCE OF BATH : Once the bath is prepared, daily addition should be made once during the day. Addition should be made when pH falls below 8. Always maintain pH between 8-9. New bath should be prepared once in week or once in 15 days, depending on the work load. PRECAUTION : 1. Since the product is alkaline in nature always wear PVC/Rubber gloves while handling or working with this product. 2. Any splashes on skin or eyes should be flushed off with plenty of water and thereafter immediately consult physician. 3. Use of eye goggles and apron is recommended. PACKING : 15 Kgs & 50 Kgs.

INTRODUCTION : CORONIL-555 is an antirust chemical compound that is readily soluble in water. It is widely used to give temporary protection against rusting of steel tubes, pipes, strips, profiles and various other ferrous parts, during process. CORONIL-555 is an antirust chemical compound that is readily soluble in water. USES : 1) It can be used as an anti-rust treatment after acid pickling or phosphating. The acid pickled or phosphated parts after rinsing are dipped or sprayed with the solution of CORONIL-555. 2) It can be used as a Passivation cum Neutralizer for machined components, for multi-metal assemblies, for ground parts and for various maintenance jobs after cleaning. It can be used either by dip, spray or by circulation. 3) It can be used as an antirust additive for : (a) Air-testing in water. (b) Hydro testing (especially of pipelines). 4) It can be added to cutting coolants or machining fluids to prevent rusting of cutting tools and workpieces for a few days.
