Surfactants are so-called surface-active substances, as they reduce the surface tension of liquids due to adsorption at the surface. Surfactants are categorized according to the nature of the hydrophilic group:
Surface Treatment of metals can be of vital significance in numerous commercial enterprises. Today there can be a few reasons why it is important to change the surface properties of metals.
For instance is surface treatment of metals utilized for:
Chemtex Speciality Ltd. manufactures a wide range of Surface treatment chemicals that modifies the metal surface for better surface finish such as derusting, phosphating and passivation. Various procedures are there for the metal surface treatment. Metal surface treatment involving Metal Surface Treatment Chemicals, is a process where metal parts to be painted are prepared. Coatings Pretreatment is the name commonly referred for preparation. The preparation involves creating a barrier for protecting the metal against corrosive environment. For creating a proper metal surface treatment, the Metal Surface Treatment Chemicals or film must impart equal potential to the surface and neutralize the possible anodic and cathodic corrosion areas so that it can provide an absorptive base for adhesion to finishes, like paints.
