Case Study: Influencing Factors of Thickening of Waterborne Coatings During Storage This case focuses exclusively on waterborne coating systems and summarizes six core, practical causes of post-storage thickening that are highly consistent with on-site production conditions. Thickening during ...

Case Study: Electrical Breakdown in Electrophoretic Coating Electrical breakdown is one of the most disruptive and costly defect classes on electrophoretic coating (electrodeposition) lines. It occurs when the local electric field strength exceeds the dielectric strength of the newly deposited film, ...

Case Study: Cratering in Waterborne Coatings after Long-term Storage Cratering in waterborne coatings rarely appears at the moment of manufacture; it develops gradually during static storage and becomes obvious only after spray application. The defect stems from unbalanced surface tension, foreign ...

Case Study: Solvents in Anodic Electrophoretic Coatings Alcohol ether solvents serve as key cosolvents for anodic electrophoretic coatings, functioning to improve resin solubility and enhance the leveling performance of coating films. Because their dosage has an outsized effect on bath stability and ...

Case Study: Functions and Maintenance of Degreasing Solution in Electrophoretic Coating The purpose of degreasing is to remove grease and oil contaminants from workpiece surfaces, providing a clean, activated substrate for subsequent phosphating and passivation. Control of the degreasing solution ...

Case Study: Main Factors Affecting Yellowing of Light-Colored Electrophoretic Coatings Yellowing of electrophoretic coatings after baking is a common quality issue in the electrophoretic coating process, and it is particularly prominent on light-colored or white films. Yellowing is not caused by a ...

Variations of Bath Solution pH and Conductivity at Different Temperatures 1 Introduction In electrophoretic coating, pH and conductivity (K) are fundamental as well as core indicators for electrophoretic coatings. Compared with indicators such as ash content, solvent content and MEQ value, pH and ...

Effecten van nat spuiten en droog spuiten op de prestaties van watergedragen verf Nat spuiten: Verfdruppels bereiken het werkstuk in een vloeibare, natte toestand, waardoor er voldoende tijd is voor vloei en coalescentie van emulsiedeeltjes om een continue verffilm te vormen. Droog spuiten: Een ...

Analyse van functie en mechanisme van oplosmiddelen in elektroforetische coatings I. Functies van oplosmiddelen in elektroforetische coatings Voornamelijk samengesteld uit alcoholen en ether-alcohol co-oplosmiddelen, dienen oplosmiddelen in elektroforetische coatings als belangrijke regulerende ...
