CHROMATIZING Aluminium chromate and its applications What we call as phosphating to steel an iron is called chromating for aluminium surfaces. Also it is knows as alodine coating. There are yellow, green and transparent chromating types. Yellow chromate coats Cr+6, green chromate coats Cr+3. Coating weight can vary according to application time and coating type. Drying temperature must not pass over 65 º C for yellow chromate and 85 º C for green and transparent chromate coatings. It is importat to provide clean, grease free surface before chromate application. If hot degreasing bath is prepared, caustic bath and following nitric acid bath can be used for pickling. On the other hand, acidic degreasing baths have pickling ability with itselves. Chromating and paint adhesion will be much better on pickled and degreased aluminium surface.

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.

COROSEAL-108 is a neutral liquid chemical consisting of surfactants, dispersants and corrosion Inhibitors. It is a multipurpose cleaning agent, widely used for removal of soils, oils, cutting fluids, Stamping, buffing and drawing compounds from ferrous as well as non-ferrous metal surfaces. COROSEAL-108 is easily soluble in water at all proportions and is very safe to use as it does not contain any chlorinated solvents, phenols, chromates, nitrites or cresols. It is non-toxic and biodegradable.

Bio Degradable Degreasing is an alkaline liquid chemical consisting of surfactants, dispersants and corrosion inhibitors. Bio Degradable Degreasing is a multipurpose cleaning agent, Bio Degradable Degreasing widely used for removal of soils, oils, cutting fluids, stamping, buffing and drawing compounds from ferrous as well as non-ferrous metal surfaces. Bio Degradable Degreasing is easily soluble in water at all proportions and is very safe to use as Bio Degradable Degreasing does not contain any chlorinated solvents, phenols, chromates, nitrites or cresols. Bio Degradable Degreasing is non-toxic. Bio Degradable Degreasing can be used by wipe, immersion or spray in various types of cleaning equipments such as tumblers, vibrators, agitators, power washers, steam cleaners, immersion or agitated tanks, ultrasonic or vapour cleaners etc. Since Bio Degradable Degreasing contains corrosion inhibitors, no rinse is required after cleaning hence Bio Degradable Degreasing cleans and protects simultaneously. Bio Degradable Degreasing Protection period may depend on operating parameters and indoor conditions.

VCHEMKLIN is designed to simplify pre-paint treatment of metal aircraft surfaces like wing sections, fuselages as well as automobiles and tractor assemblies. Complete assembled planes can be cleaned and conditioned right on the field without the use of special equipment. Easy hand application of VCHEMKLIN by brushing, swabbing or spraying provides thoroughly clean passivated surface ready for touch-up or complete refinishing. FAST, LOW COST METHOD :- Passivating with VCHEMKLIN is not intended to replace anodizing and chromatising in aircraft and automobile manufacturing. However it produces similar results faster and at much lower cost where those processes are impractical or unavailable. REMOVES, PREVENTS CORROSION :- Light oxides and surface corrosive residues are quickly and easily removed by merely applying VCHEMKLIN by wipe method and rinsing with water. Surfaces is made chemically inert oxide and soil free to prevent corrosion from spreading under paint coatings.
