Phosphate coatings-the recognised pre-treatment for steel substrates
The recognised pre-treatment for steel substrates just prior to application of powder is phosphating which can vary in coating weight. The greater the conversion coating weight the greater the degree of corrosion resistance achieved; the lower the coating weight the better the mechanical properties. It is therefore necessary to select a compromise between mechanical properties and corrosion resistance. High phosphate coating weights can give trouble with powder coatings in that crystal fracture can occur when the coating is subjected toRead More …
Considerations for Choosing a Coolant for metal working process
Different metal working processes have varying cooling and lubrication needs. Coolants have many properties that increase their efficiency, extend their life, and minimize the potential to damage tools and products. Therefore, when choosing a coolant, many factors need to be considered. These considerations include: Tramp oil rejection Ability to settle out solids Bacterial resistance Corrosion and rust resistance Emulsification capability Foaming nature and resistance Optimal coolant life Longevity of coolant as measured against current industrial standards Cost of coolant ChemicalRead More …
Paint Removal
When repainting a part,prior to application of the new paint coat the old,paint often must be removed. The waste reduction assessment should start by examining what causes the need for repainting: inadequate initial part preparation; defects in coating application; equipment problems; or coating damage due to improper handling. While no process is perfect, reducing the need for repainting has a direct effect on the volume of waste generated from paint removal. Once the need for paint stripping has been reducedRead More …
ASTM D7803-New standard for preparing HDG steel for powder coatings
Bridges are one example of construction projects that are often built from hot-dip galvanized steel. How to coat this steel without adhesion failure of the powder system is explained in the new ASTM standard. The new standard, ASTM D7803, “Practice for Preparation of Zinc (Hot-Dip Galvanized)Coated Iron and Steel Product and Hardware Surfaces for Powder Coatings” covers surface preparation and thermal pretreatment of iron and steel products and hardware which have not been painted or powder coated previously (Practice D6386).Read More …
Advantages of UV-curable powder coatings
UV-curable powder coating is one of the fastest coating chemistries available. From start to finish the entire process for finishing MDF takes 20 min or less, depending on chemistry and part geometry, making it an ideal finish for applications that require a quick turnaround. A completed part requires only one coat, allowing increased production with 40 to 60 percent less energy than other finishing processes. The UV-curing process is much simpler than other finishing technologies. Curing of a liquid finishRead More …
Why the use of yellow iron oxides in high-temperature-cured coatings is limited
Standard yellow iron oxides are the ideal inorganic pigments to develop a wide range of color shades due to the advantages in performance and cost provided by their high hiding power and opacity, excellent weather, light and chemical fastness, and reduced price. But their use in high-temperature-cured coatings such as coil coating, powder coatings or stoving paints is limited. Why? When yellow iron oxides are submitted to high temperatures, their goethite structure (FeOOH) dehydrates and partially turns into hematite (Fe2O3), which is the crystal structure of red iron oxide. This is why the standard yellow iron oxide that exists before curing becomes darker and browner . This change can take place from temperatures close to 160ºC, depending on the curing time, the binder system and the coating formulation itself.
Coil coating is a continuous industrial process
Coil coating is a continuous industrial process in which multiple layers of organic film are applied and cured on a moving metal strip. The paints used are liquid (solvent-based) and are generally composed of polyesters with acid- or hydroxy- endgroups able to crosslink with melamines or isocyanates to form a complete network with film properties that are tailored to the final application of the coated metal panel (building products, beverage cans, domestic appliances, etc.). The total film thickness is aroundRead More …
