Produktnr. 9905222 Rev. 00_29.04.04

Application UNOPOL U 570 is a water miscible, mineral oil containing, semi synthetic drawing lubricant for drawing of copperwire in rod breakdown systems. Moreover the product is used for medium and fine wire drawing of bare, tinned and silverplated copper wire in single and multiwire machines down to smalles diametersof 0,10 mm. Based on its high percentage of natural and synthetic fatty esters and selected emulsifiers and surfactants emulsions of UNOPOL U 570 show excellent lubricity properties combined withexcellent rinsing and cleaning power. Recommendation for application Depending on the starting and final diameter of the wire UNOPOL U 570 can be used in the following concentration: Rod wire drawing:Medium wire drawing: Fine wire drawing: Continuous annealing: ca. 14 – 18 % ca. 4 – 6 % ca. 6 – 8 % ca. 1 %

Properties:
♦ Water miscible ♦ mineral oil containing ♦ semi synthetic ♦ very highlubricity ♦ good cleaning properties ♦ long lifetime of the emulsion

Emulsion temperatures between 35° and 45° are proved to be most favourable. C C UNOPOL U 570 is easily emulsifiable in water. Toreach a fast and effective mixing it is advisable to add the concentrate to the water in an area of high turbulence or use a conventional mixing unit. For charging the system the water should have atemperature between 15 and 45° C and a total hardness of 8 - 15 ° dH. We recommend to use DI-water for topping up.
