Conversion Coating of Galvanized Steel
Iron phosphates or cleaner-coater products produce little or non-detectable conversion coatings on zinc surfaces. Many multimetal finishing lines use modified iron phosphates which offer cleaning, and leave micro-chemical etch on zinc substrates to provide adhesion properties. Many municipalities and states now have limits on zinc PPMs, forcing metal finishers to provide treatment of any solutions in which zinc substrates are processed. The zinc phosphate conversion coating is, perhaps, the highest quality coating that can be produced on a galvanized surface. ToRead More …
Chemical surface preparation before powder coating
Particular application is closely related to the nature of the surface being cleaned and the nature of the contamination. Most surfaces powder coated after cleaning are either galvanized steel, steel, or aluminum. Since not all chemical-type preparations are applicable to all these materials, the preparation process selected depends on the substrate material. For each material, the type of cleaning will be discussed and its unique features for that substrate will be explained. Specific application processes are quite similar for eachRead More …
What is the application of calcium carbonate in paints?
Calcium carbonate is a non-toxic, odorless, non-irritating white powder and one of the most versatile inorganic fillers. Calcium carbonate is neutral, substantially insoluble in water and soluble in acid. According to different calcium carbonate production methods, calcium carbonate can be divided into heavy calcium carbonate and light carbon. Calcium acid, colloidal calcium carbonate and crystalline calcium carbonate. Calcium carbonate is a common substance on the earth. It is found in rocks such as vermiculite, calcite, chalk, limestone, marble, travertine, etc.Read More …
What are the hazards of powder coatings?
Most powder coating resins are less toxic, and the curing agent is significantly more toxic than the resin. However, when formulated into a powder coating, the toxicity of the curing agent becomes very small or almost non-toxic. Animal experiments have shown that there is no death and injury symptoms after inhalation of the powder coating, but there are different degrees of irritation to the eyes and skin. Although general powder coatings have no obvious harm to the human body, theyRead More …
Cleaning functions most importantly in maximizing powder coating results
The highest quality powder coating will provide excellent results only if the pretreatment (cleaning, phosphatizing, conversion coating) is done correctly and the overall pretreatment system is maintained up to its potential. Powder coating brings pretreatment back to the basics of cleaning, rinsing, phosphatizing,and seal rinsing. To maximize the benefit derived from powder, the pretreatment system must provide a clean conversion coated product in a dry state to the powder booth. Surface preparation encompasses more than conditioning or improving a substrateRead More …
Economic advantages of powder coatings
Energy and labor cost reduction, high operating efficiencies, and environmental safety are advantages of powder coating that attract more and more finishers. Great cost savings can be found in each of these areas. When compared with a liquid coating system, a powder coating system has several obvious significant economic advantages. There are also many advantages that may not appear significant by themselves but, when collectively considered, contribute substantial cost savings. Although this chapter will try to cover all cost advantagesRead More …
Advantages of Epoxy Polyester Hybrids
Epoxy powder coatings based on newer technology are known as epoxy-polyester “hybrids” or “multipolymer” systems. This group of powder coatings could be considered simply part of the epoxy family, except that the high percentage of polyester utilized (often more than half the resin) makes that classification misleading. The properties of these hybrid coatings are more closely akin to epoxies than polyesters, with a few notable exceptions. They show similar flexibility in terms of impact and bend resistance, but produce slightlyRead More …
