Surface Prepration

Substrate surface preparation is an essential part of our Thickfilm coating deposition process.

Perfect Bonding

By removing detrimental foreign matter (oil, grease, dirt, salt) and small machining imperfections, we ensure outstanding adhesive bonding of the coating to every surface.

Because surface impurities are a leading cause of coating failures and because our coating is the outermost layer of a surface, we heat and clean most metallic surfaces in a vapor degreaser using appropriate universal solvents. This process removes oils, soils and solvents that could mask microscopic pores within the surface.

We then ensure the coating area of each part to be as uniform as possible. By imposing a glass bead blasting process (or other appropriate technique), we remove burrs and small machining imperfections. This eliminates sharp edges, nicks, oxide layers and residues, and ensures the best possible performance of our metal coatings.

Any new contaminants that might be added to a part during the bead blasting process are removed by further deep cleaning. Various solvents, presurized gas, ultrasound vibratory cleaning and other methods can be utilized. They are then closely inspected to ensure the desired results.
