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.

VCHROM - AL is a concentrated colourless liquid which can be used to produce colourless non-chromate films/coatings on aluminium and its alloys. This process is most suitable to provide under-paint corrosion and to provide good bonding of powder coats or liquid paints with the aluminium surface. VCHROM - AL poses no pollution problems as compared to chromate treatments. VCHROM - AL process is very simple and economical as mild degreasing and pre-treatment takes place simultaneously while giving a good colourless coating that suits perfectly well prior to coating or painting. If oil contamination is more on surface, separate cleaning in ALM-81 is recommended, using 3-5% concentration. USES : VCHROM - AL process can be used on any aluminium surfaces or on aluminium alloys. It may not be suitable on certain alloys or castings as it may tend to produce a superficial black film, which needs to be washed thoroughly well with water.
