ANTI RUSTING PROPERTY OF DEGREASER


(2000)

We are in the development of special type of degreaser which must have satisfactory degreasing properties as well as have rust inhibition properties after degreasing. This type of chemicals will be suitable for steel plant where cold rolled steel sheets are kept for at least a week or more. The degreasing chemical is highly alkaline in nature, powdered in form and used in continuous electrolytic, spray or dip type of cleaning process. Can anybody help me to select suitable material which we can incorporate in our alkaline degreasing formulations?
