Microsoluble Metalworking Fluids
ValCOOL Microsoluble Machining Fluids are water-based coolants that incorporate an emulsion - oil stabilized in water. The oil in these products can range from highly refined petroleum oil to polymerized vegetable feedstocks. ValCOOL Microsoluble and Semi-Synthetic Metalworking Fluids have excellent versatility and are capable of working in basically any machining process. The products vary in their oil content, additive composition, and corrosion inhibition package. Regardless of the product chosen machinists can be assured all ValCOOL Microsolubles inhibit foam, have outstanding sump life, and are very friendly to machinists' skin.
Questions About Our Products?
Contact our Sales Engineers.
Our Sales Engineers are widely regarded as the most competent and responsive in the business: they know the material, the workpiece, the tools and the fluids that you need to make it right. Together with our Field Application Engineers, they’re available with on-site assistance and technical support when you need it.
Applications
ValCOOL often recommends Microsoluble chemistries in most applications as these chemistries allow for significant lubrication and extreme heat dissipation. The Microsoluble name is used as the micelle in these chemistries is extremely small such than in many cases people often don't realize there is actually emulsified oil in the product. The stability of the micsolubility of the chemistry provides for significantly long sump life and tramp oil rejection properties that keep coolant running clean.

ValCOOL wants to share our fluid expertise with the industry.”
Choosing the Right Microsoluble Machine Fluid for Your Operation
Not every microsoluble metalworking fluid is built for the same job. Some ValCOOL formulations, like VP 700 P, a fighting-grade, low-oil semi-synthetic, are designed for dirty environments such as cast iron machining and grinding, where chip and swarf management matters as much as cooling performance. Others, like Emerald Cut WSX, are formulated as halogen-free and petroleum oil-free options for shops standardizing on chlorine-free chemistries across their fluid inventory.
Multi-metal capability is another factor to weigh. VP 805P is built to perform consistently across materials like Inconel, cast iron, and aluminum in the same shop, without needing a separate coolant for each job. If you're unsure which semi-synthetic metalworking fluid fits your specific mix of materials and operations, our services team can help match a product to your process.
Semi-Synthetic Metalworking Fluids vs. Other Coolant Chemistries
Semi-synthetic metalworking fluids sit between soluble oils and full synthetics on the coolant spectrum. A semi-synthetic combines a soluble oil with a synthetic chemistry, meaning it still contains oil and forms an emulsion, unlike a true synthetic coolant, which contains no oil at all. This blend gives semi-synthetic metalworking fluids a balance of the lubricity soluble oils are known for and the cleanliness and stability more typical of synthetics.
ValCOOL's microsoluble metalworking fluids fall into this semi-synthetic category, using an oil-in-water emulsion with a micelle size small enough that the coolant often doesn't visually appear to contain oil at all. This makes microsoluble machine fluids a practical middle-ground choice for shops that need better lubrication than a synthetic can offer without the heavier tramp oil buildup and sump maintenance that come with a conventional soluble oil.
