5 P-TEC 7210 Type SOLUBLE OIL BASE PACKAGE FOR PARAFFINIC BASE OILS Technical data (Typical) Appearance Dark Brown Liquid Odour 29.5 ºC (ASTM D1298) Typical 1.003g/cc Kinematic 40 ºC (ASTM D445) 930 cst Total Acid Number (ASTM D 974) Total Base Number (ASTM D 2896) 0 C & 50 C (48 Hours) 25 mg KOH/g 85 mg KOH/g Bright clear & stable APPLICATION: A conventional watermix metalworking fluid concentrate providing excellent emulsification and corrosion inhibition, suitable for use in Paraffinic base oils. Finished products can be further enhanced by incorporating functional additives such as EP, lubricity agents and speciality corrosion inhibitors. CONCEPT : The concept is to provide the customer with a cost effective solution and simplifying the production of high oil content soluble oils. Biocides are an option for use at treat rates up to 3% to prolong the life time of the emulsions used in service. BASIC BLEND RATIOS % Material Base Oil (150SN) 15 P-TEC Biocide
