Dry Grit Blasting

The most generally established method of surface preparation for coatings application is dry flit blasting. Dry flit blasting uses a highly concenrated stream of grit projected at a surface to remove rust, mill scale, or other contaminants, and to create a rough surface good for adhesion. Indeed, when modern coatings are applied, there is no truly satisfactory or economically - equivalent alternative process.

Surface cleanliness standards

There are various degrees, or standards, or surface, cleanliness achievable by abrasive blasting. Th abrasive blast cleaning standards for new steel in most common use are from NACE.

several methods are available to measure surface profile:

Hot zinc phosphating

Sukee Speciality Coatings offers a hot zinc phosphatizing finishing treatment to prepare metal or steel pieces for painting or coating, helping prevent corrosion.

Phosphatizing differs from traditional painting or coating because the surface of the metal is chemically changed to a new substance. This is important because the new coating will not chip or scratch, ensuring that the base material is not vulnerable to corrosion and wear.
