SEMI SYNTHETIC COOLANTS
Semi-synthetic coolants are metalworking fluid concentrates that contain a small amount of oil (usually less than 30%) as well as synthetic lubricants and other additives. When mixed with water, they form a translucent fluid. Semi-synthetics combine the physical lubricity of soluble oils with the chemical lubricity, cooling and cleanliness of synthetic coolants.
