When baking water-based paints, gloss issues caused by oven temperature deviations stem from the unique physical properties of water and the specific mechanism by which water-based resins form films through the fusion of particles. Let us first examine the film-formation…
In UV curing applications, there is a common issue that frequently leads to misjudgment: the surface feels dry and tack-free to the touch and looks perfectly normal, yet the coating fails the cross-hatch adhesion test. When encountering this for the…
In spray painting operations, the choice of spray booth directly impacts coating quality, environmental compliance, and production costs; consequently, many people find themselves torn between selecting a dry spray booth or a water curtain spray booth. In reality, there is…
In non-electrostatic spraying processes, more than half of the paint may fail to effectively adhere to the workpiece, instead being lost during the spraying operation. This represents a significant opportunity for cost optimization. Today, we will discuss how to scientifically…
Differences Between Electrophoretic Coating Followed by Powder Coating and Direct Powder Coating, as Well as the Underlying Mechanisms and Applications In the field of metal surface treatment, powder coating is a common and environmentally friendly process. However, when faced with…
"Water-based primer + solvent-based topcoat" is a highly discouraged and risky application, with a failure rate far exceeding its success rate. The incompatibility stems primarily from fundamental differences in the film-forming substances, solvent systems, curing mechanisms, and physical properties of…
When it comes to high-temperature resistant paint, customers often ask: "Can this high-temperature paint help me adjust the color like a polyurethane topcoat?" Even on many design drawings, you will see a very "natural" marking: "How many degrees Celsius is…
When the coating is applied to the substrate, adhesion is generated during the drying and curing process. It is generally believed that these forces exist between the coating and the substrate: covalent bonding force, hydrogen bonding force, dispersion force, dipolar…
Water Transfer Printing (WTP) is an advanced surface decoration technology that transfers patterns from a water-soluble film onto the surface of three-dimensional objects using water pressure. It is widely used in automotive interiors, electronic products, military equipment and household items…
For painting of PP (polypropylene) bumpers, the core challenge lies in the extremely low surface energy, high inertness, and solvent resistance of PP material, which makes paint adhesion difficult. Therefore, the process flow revolves around the core issue of "how…
