Passivation Chemicals By Kemfin Chemicals (P) Ltd.

In this market of chemicals, our name is popular as one of the reckoned manufacturers and exporters of Phosphate Passivation Chemicals. All these chemicals lower down the chemical reactivity of the metals when coated. Due to this, the level of corrosion gets lower down on the metal surface thereby maximizing the life of the tool. Our expert professionals make sure that we use only genuine quality of components for formulating these chemicals. All the industrial norms and standards are followed while formulating these Phosphate Passivation Chemicals.         Further Details Kemlyte-333(Phosphate Passivation Chemicals) specially formulated chemical to eliminate contaminants from the pretreatment metal surfaces and also applied to hexavalent chromium coating in order to avoid attachment of oxides, chlorides etc., present in the air.

Inhibiting Efficiency Highly Hazardous Product Operating Data Concentration 0.025 0.30% by v/v Temperature 60 C Dip Time 30 secs pH 4 - 6 Applications Dip/Spray Product Operating Procedure Bath Make UpFor every 100 ltr. of water 0.025 ltr. of kemplyte-333 to be added in the bath mix thoroughly and heat the bath at 60-70oC. Bath should be made preferably of D.M. water or with water, which has total dissolved solids less than 225 PPM. Product Application Equipment'sM.S. Tank/Spray Plant. Testing and Control Procedure Free AcidityPipette out 100 ml bath solution sample and add drops of Indicator Bromocresol Green. When the solution becomes light green note the consumption of N/10 sodium Hydroxide in the burette applications. This will give free acidity. Total AcidityPipette out 100 ml. of bath solution in a conical flask. Add 5  6 drops of Phenolphthalein indicator. Titrate it against N/10 sodium hydroxide, when the colour of the solution in the flask becomes permanent violet 9 for 15 secs) consumption of N/10 sodium Hydroxide in the burette application. This will give it total acidity. Chemical ReplenishmentTo raise the pointage by 1 add 20 ml in 100 ltr of bath solution. Safety Measures Kemlyte-333 is a chromic acid based chemical. Proper disposal of effluent is required after neutralizing chromium. General Information Corrosion Resistance Good Paint Adhesion Good Gloss Retention.
