Whether you’re manufacturing automotive parts, packaging bottles, consumer goods, or carbon fiber components, you likely face the same persistent challenge: coatings, inks, and adhesives simply refuse to stick to these materials. In short, the goal is to get coatings, inks,…
Why Is Wastewater from Paintshop Difficult to Treat? Wastewater from a paint shop is not a single, uniform stream; rather, it is a mixture of several distinct types: pretreatment wastewater (containing phosphorus and zinc), degreasing wastewater (alkaline and oily), paint-booth…
After opening the paint container: stirring, filtering, and induction - three steps addressing three distinct issues. Once the lid is open, first inspect the rim and surface. Only after assessing the state of the liquid surface should the mixer be…
Powder coating cracking during impact tests? A combination of dual-layer coating and slight oven temperature adjustments can boost impact strength from 30 kg·cm to 50 kg·cm. Many coating facilities achieve perfect scores on visual inspections but stumble when it comes…
You might have a spray gun claiming a "99% powder coating transfer efficiency," yet actual tests show it only climbing from 60% to 75%, with the rest drifting into the filter cartridges. The root cause usually isn't the gun itself,…
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…
