Marvell Solube EP Nitrate-Free Cutting Oil Coolant 20L

Product Description

Marvell Solube EP Nitrate-Free Cutting Oil Coolant is a high-performance, water-miscible metalworking fluid concentrate developed to provide effective cooling, lubrication, corrosion protection and extreme-pressure performance during machining operations. When correctly mixed with water, the concentrate forms a stable working emulsion that helps control heat and friction at the cutting zone while supporting tool life, workpiece quality and reliable machine operation.

This product combines the cooling efficiency of water with the lubricating properties of a soluble cutting oil. During machining, the water phase carries heat away from the cutting tool and workpiece, while the lubricating and extreme-pressure components help reduce friction and metal-to-metal contact. This balanced performance makes Marvell Solube EP suitable for workshops requiring both effective cooling and dependable lubrication from one metalworking coolant.

The extreme-pressure additive system is designed for machining operations where a basic general-purpose soluble oil may not provide sufficient load-carrying performance. It helps protect the cutting interface during demanding operations, reducing the potential for tool-edge loading, metal pickup, scoring and excessive friction. When used at the correct concentration, Marvell Solube EP can support improved tool life, smoother machining and a more consistent surface finish.

Marvell Solube EP is formulated without nitrate, making it suitable for workplaces, production facilities and customers specifying a nitrate-free soluble cutting fluid. The nitrate-free designation relates specifically to the formulation’s nitrate content and does not mean that normal workplace handling precautions can be disregarded. Operators should always follow the product label, current Safety Data Sheet and workplace chemical-management procedures.

The convenient 20-litre pack is suitable for individual CNC machines, conventional machine tools, maintenance workshops, engineering businesses, fabrication facilities and production sites that do not require a full industrial drum. It provides a practical quantity for charging smaller machine sumps, conducting production trials or maintaining several machines with moderate coolant consumption.

Testing is particularly important where staining, discolouration, residue, paint compatibility or workpiece appearance is critical. The trial should use the actual production material, water supply, operating concentration, machine components and intended processing conditions.

Key Features and Benefits

Extreme-Pressure Protection

Very high pressure can develop where the cutting tool contacts the workpiece. Under these conditions, an ordinary lubricant film may become too thin to prevent direct contact between the tool and the metal.

Marvell Solube EP contains extreme-pressure performance designed to strengthen protection under demanding boundary-lubrication conditions. This helps reduce friction, scoring, metal pickup and tool-edge loading during heavier machining operations.

Improved protection at the cutting interface can support longer tool service life and more consistent machining. Actual results depend on the tool material, tool condition, coolant concentration, cutting speed, feed rate and workpiece alloy.

Effective Cooling Performance

Machining generates heat through friction and deformation of the workpiece material. Excessive heat can reduce tool life, affect component dimensions and damage the finished surface.

When correctly diluted, the water phase of Marvell Solube EP efficiently carries heat away from the cutting zone. Continuous coolant flow helps control the temperature of the cutting tool, workpiece and surrounding machine components.

Correct coolant delivery remains important. Nozzles should be positioned so the working fluid reaches the cutting interface in sufficient volume. Blocked, damaged or incorrectly positioned nozzles can reduce cooling performance even when the sump concentration is correct.

Lubrication and Surface-Finish Support

The lubricating components help reduce friction between the cutting tool, chips and workpiece. Reduced friction can promote smoother cutting, limit material adhesion and support a more consistent finished surface.

A coolant mixture that is too weak may not provide sufficient lubricity or corrosion protection. An unnecessarily strong mixture may increase operating cost, residue, foaming or operator discomfort. Concentration should therefore be selected and maintained according to the actual machining operation.

Nitrate-Free Formulation

Marvell Solube EP is formulated without nitrate. This makes it suitable for facilities whose chemical-management policies, customer requirements or manufacturing specifications call for a nitrate-free metalworking fluid.

Normal controls remain necessary when handling both the concentrate and working emulsion. Operators should avoid prolonged skin contact and unnecessary exposure to coolant mist. Good ventilation, appropriate machine guarding and correct coolant maintenance should form part of the workplace control system.

Corrosion Protection

Water-miscible cutting fluids require corrosion inhibitors to protect workpieces, machine surfaces, coolant sumps and circulation components. Marvell Solube EP is formulated to provide corrosion protection when mixed and maintained at the correct concentration.

Corrosion protection may decrease if the mixture becomes excessively diluted, contaminated or degraded. Regular concentration testing is therefore essential. Machined components intended for extended storage or exposure to humid conditions may require an additional temporary corrosion-preventive coating.

Chip and Swarf Removal

Adequate coolant flow helps move chips, swarf and fine metal particles away from the cutting zone. This reduces the likelihood of chips being recut or trapped between the tool and workpiece.

Coolant filtration should be appropriate for the machining process. Grinding and fine-finishing applications typically require finer filtration than general turning or milling. Excessive metal accumulation can interfere with pumps, consume additives and reduce coolant-system cleanliness.

Practical 20-Litre Packaging

The 20-litre container is a convenient option for smaller workshops, individual machines and controlled coolant trials. It provides sufficient concentrate for preparing a substantial quantity of working fluid while avoiding the storage and handling requirements associated with a 205-litre drum.

The package is suitable for controlled dispensing with a clean hand pump, tap or dedicated pouring device. The container should be kept securely closed between uses to prevent contamination by water, dirt, swarf or other workshop fluids.

Metalworking-Fluid Management

The service life of a water-miscible cutting fluid depends on more than the initial concentrate quality. Water hardness, chloride content, contamination, operating temperature, filtration, tramp oil and microbial activity can all influence coolant stability and machining performance.

Very soft water may encourage foaming, while extremely hard water may contribute to deposits, instability or residue. Water quality should be checked before preparing a large coolant charge or filling an important production system.

Coolant concentration should be measured regularly using a clean, calibrated refractometer and the correct refractometer factor for the product. Refractometer readings can be affected by tramp oil, dissolved contamination and aged coolant, so additional testing may be required for critical systems.

Operators should monitor the fluid for changes in appearance, odour, foam, residue, separation, corrosion and machining performance. An abnormal odour can indicate microbial contamination or poor system condition and should be investigated promptly.

Typical Physical Properties

Typical properties are representative product information and are not guaranteed manufacturing limits. Batch-specific values should be obtained from the current Marvell Technical Data Sheet or Certificate of Analysis.

Handling & Storage Advice

Store Marvell Solube EP in its original, correctly labelled 20-litre container in a cool, dry and well-ventilated area. Protect it from direct sunlight, rain, frost, excessive heat and incompatible materials.

Keep the cap or dispensing connection securely closed when the product is not being used. Do not allow water, dirt, metal swarf, used coolant, tramp oil or other contaminants to enter the concentrate container.

Avoid eye contact, prolonged or repeated skin contact and inhalation of coolant mist or machining aerosol. Appropriate workplace protective equipment may include safety glasses, protective clothing and chemical-resistant gloves selected according to the site risk assessment.

Wash exposed skin thoroughly after handling the concentrate or working emulsion. Do not use solvents, abrasive cleaners or contaminated workshop rags to clean coolant from the skin. Remove contaminated clothing and wash it before reuse.

Clean spills promptly because both the concentrate and diluted coolant can make floors extremely slippery. Contain spilled material using suitable absorbent products and prevent it from entering drains, stormwater systems, soil or waterways.

A full 20-litre container is heavy. Assess the load before moving it and use suitable lifting assistance or mechanical handling equipment where required. Carry the container using its intended handle only when it can be handled safely.

Used coolant should not be discharged to drains without confirming all applicable environmental, trade-waste and disposal requirements. Consult the current Safety Data Sheet before workplace use.

Mixing and Directions for Use

Clean the machine sump, pumps, filters, coolant lines and return channels before adding a fresh coolant charge. Residual degraded coolant, bacteria, fungal contamination, tramp oil and accumulated metal fines can quickly reduce the life of a new mixture.

Always add the concentrate to water. Begin with the required quantity of clean water and slowly add Marvell Solube EP while maintaining adequate agitation. Do not add water directly into a container of concentrate, as this can produce an unstable or incorrectly formed mixture.

Use water of suitable quality and set the concentration according to the current technical recommendation and the severity of the machining operation. Higher concentrations generally provide increased lubricity and corrosion protection, while suitable lower concentrations may provide effective cooling for lighter operations. Do not select a concentration using a generic mixing ratio without confirming the product requirements.

When topping up an operating system, prepare the required premix separately before adding it to the sump. Avoid repeatedly adding neat concentrate or water directly to the machine, as this may create localised over-concentration or excessive dilution.

Do not mix Marvell Solube EP with unknown cutting fluids. Mixing different metalworking-fluid technologies can cause separation, excessive foam, residue, reduced corrosion protection, instability or poor microbial control.

Coolant-System Maintenance

Check coolant concentration regularly using a calibrated refractometer. Record results and make adjustments using properly prepared premix.

Remove floating tramp oil with an appropriate skimmer, coalescer or separation system. Tramp oil can restrict oxygen transfer, encourage microbial activity and affect coolant performance.

Remove chips, swarf and grinding fines using suitable screening, settling or filtration equipment. Inspect pumps and coolant nozzles regularly to confirm that sufficient fluid reaches the cutting zone.

Investigate unusual odours, excessive foam, staining, corrosion, residue or emulsion separation promptly. Continuing to operate with badly contaminated or degraded coolant can affect tool life, workpiece quality and operator acceptance.
