3M has developed a number of non-flammable products that effectively clean medium- to heavy-duty soils. These products – azeotropes or blends of azeotropes – have much higher solvency than pure 3M™ Novec™ Engineered Fluids 7100 or 7200, and are useful on soils ranging from hydrocarbon and silicone oils to greases. Their higher solvency means they can clean solder flux residues and low melting point waxes. Their excellent chemical and thermal stability coupled with constant composition during boiling makes them ideal for immersion defluxing and degreasing applications.
