Description
GP D44 - Coolant for Aluminium, Titanium and General Purpose machining
A high oil content soluble oil metalworking fluid
GP Sol D44 is a boron and chlorine free high oil containing metal process fluid which produces a milky white emulsion when diluted in water. The product is compounded to form a stable emulsion in both hard and soft water and is highly inhibited against bacterial growth.
GP Sol D44 has been developed to exhibit full multi-metal compatibility and is suitable for economical use on a wide variety of machining applications.
GP Sol D44 exhibits excellent lubricity characteristics, making the product suitable for a whole variety of machining applications whilst maintaining machine cleanliness and operator acceptability.

GP Sol D44 is free of boron; boric acid has been given the status of a SVHC (substance of very high concern). Boric acid derivatives are used in a number of water-mix metal working fluids. Although there has been a lot of work to prove that the boric acid derivatives do not contain free boric acid there has been a move in the market to move away from boric acid derivatives in water-mix metal working fluids.
Bio-stability - these products give excellent bio-control maintaining bacteria levels well within the HSE (Health and Safety Executive) guidelines.
Corrosion inhibition - These products give equivalent corrosion protection, or better than boron containing products.
Operational Recommendations
GP Sol D44 is designed to be mixed with water; it has been developed to exhibit full multi-metal compatibility and is suitable for use in soft and hard water types.
Mix emulsions of GP
Sol D44 with water by adding concentrate to water and then mixing or use a suitable proportioning mixer unit, these are available on request. The use of an airline to mix the solution is not recommended. Machine top up may require a weaker dilution than the initial machine charge concentration. Recommended concentrations can vary depending on operations, materials, tooling, coolant pressure, coolant flow. The above information is given for guidance. Please contact your representative for further advice.
GP Sol D44 should always be stored indoors and protected from frost. Good standards of hygiene and housekeeping should always be adopted when using any metalworking fluid. A separate MSDS is available for this product.
As with all modern cutting fluids, concentration control is of paramount importance, therefore regular check by use of a refractometer is recommended for this product. It should be noted that the individual product refractometer correction factor should always be used to ensure accuracy.
