Drawing lubricant for copper wire

BECHEM Unopol S 630 is a mineral oil free, fully synthetic drawing lubricant for medium and fine wire systems. Bare, tinned, silver plated and nickel plated copper wire are drawn on single and multi wire systems down to smallest diameters of 0.10mm, sometimes down to 0.07mm.

BECHEM Unopol S 630 is also used in enameled wire departments. Combining synthetic lubricity additives, corrosion protection additives and surfactants solutions of BECHEM Unopol S 630 how good lubricity and cooling properties, low foaming, no stickiness but also excellent rinsing and cleaning power.

BECHEM Unopol S 630 can be used in the following concentration :
Medium wire : approx. 10 %
Fine wire (single wire) : approx. 3 – 5 %
Fine wire (multi wire) : approx. 8 – 10 %
Temperatures of the solutions between 35 °C and 45 °C are proved to be most favourable.

·  Fully synthetic
·  High lubricity
·  Very good cleaning properties
·  Very long life time of the solution
·  Meets TRGS611

BECHEM Unopol S 630 is easily soluble in water. To reach 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 initial fill and topping up we recommend to use DI water which should have a temperature between 15°C and 45°C
