Proper metal cleaning and degreasing is essential to quality metal finishing. After treatment, the metal may go on to receive many different types of coatings and finishes. The parts may be introduced to a conversion coating such as iron phosphate or may go directly to liquid or powder paint coating. The desired finish, type of substrate, and type of treatment system will determine the chemicals necessary to achieve highest quality finish. These variables will not only help to dictate the choice of cleaning and degreasing chemicals, but also the temperature that the system will operate at and the time it will take for parts to be completely treated. These variables need to be closely scrutinized to determine the best course of action that will deliver the perfect finished product and achieve the lowest operating costs.
Metal cleaning chemicals can be simple surfactant based cleaners and degreasers, solvents, or etchants. Crest has a variety of products in each of these categories that are formulated with these processing lines in mind. There is enough variation in our product line that they can be used for anything from aviation aluminum cleaning to industrial steel pipe cleaning.
