Solvents are essential formulation ingredients for many coatings jobs. Without them, paints and coatings products would simply not perform as well. However, choosing the appropriate solvent or solvent blend for a particular application is often not easy. Many variables must be considered, and the choice is system-dependent. For example, reformulating an existing product is not as simple as substituting another solvent.
To use a new solvent, a product typically needs to be completely reformulated to maintain desired performance attributes. Because formulations are complex, and reformulations could result in a poorer-performing product, it is wise for formulators to work with their solvent suppliers to find the best solvent system for the desired application.
