In recent years, the widespread adoption of fiber-reinforced plastic (FRP) parts across industries has heightened the demand for eco-friendly and high-quality coatings. Ultra-fine powder coatings have emerged as a promising solution, offering a cost-effective and environmentally friendly alternative to traditional solvent paints. However, challenges such as low powder flowability and high curing temperatures hinder their application on FRPs. In response, a nanocomposite comprising [specific components] was developed and added to ultra-fine powder coatings. The study found that incorporating 0.3–0.5 wt% of the nanocomposite significantly improved powder flowability and enhanced curing reactions, reducing curing temperatures by 20 °C. This innovation resulted in a 50% reduction in film thickness and notable improvements in final appearance, roughness, and water resistance. The nanocomposite demonstrated its efficacy in enhancing flowability and curing reactions, presenting a breakthrough for obtaining thin, qualified films on FRP substrates and expanding the application of ultra-fine powder coatings in the coating industry.
Poor powder catchment efficiency, is a limiting factor in the adoption of Directed Energy Deposition for the processing of expensive materials, complex shapes and for the sake of energy efficiency. Powder catchment efficiency increased to a value of 56% on a flat plane, compared to 26% under the same conditions without magnetic assistance. The mild […]
Electrochemical reactions represent essential processes in fundamental chemistry that foster a wide range of applications. Although most electrochemical reactions in bulk substances can be well described by the classical Marcus-Gerischer charge transfer theory, the realistic reaction character and mechanism in dimensionally confined systems remain unknown. The oxidation rate is correlated quantitatively with various crystallographic and […]
Weak bonding between coatings and substrates can result in the failure of components subjected to high-temperature fatigue leading to substantial economic losses and lower production efficiency. Coating spalling is typical in applications where large alternating thermal cycles are present. Thus, tight bonding between coating and substrate is critical to avoid thermal failure at high temperatures. […]
