Black One Coat Enamel RTU Powder: Enamel Manufacturers Say Goodbye to Bubble and Pore Issues
According to relevant statistics, for some enamel manufacturers using common enamel glazes, the defective rate due to air bubbles and porosity can reach as high as 15%-20%, undoubtedly resulting in significant economic losses for enamel manufacturers.
The causes of air bubbles and porosity are complex, primarily including uneven glaze composition, irrational particle size distribution, improper surface treatment of the metal body, and poor firing process control. For example, when the flux content in the glaze is too high or too low, it affects the glaze's melting temperature and fluidity, making it difficult for gases to escape within the glaze layer, thus forming air bubbles. Furthermore, impurities such as oil and rust on the metal body surface can hinder the proper bonding of the glaze to the green body during the enameling process, and easily cause air bubbles and porosity during firing.

Black one coat RTU enamel powder effectively prevents these issues through advanced formulation design and strict production processes. In formulation, precise control of raw material ratios ensures uniform and stable glaze composition. Optimized flux content and types guarantee excellent melting properties and gas release during firing. In production, advanced grinding equipment and techniques guarantee uniform particle size distribution, significantly reducing bubble formation caused by size variations. Additionally, professional guidance is provided for substrate surface treatment, good for ensuring clean, smooth surfaces that create optimal conditions for glaze adhesion.
A renowned enamel cookware manufacturer previously experienced a defect rate as high as 18% in its enameled pots due to bubbles and pores before using black one coat RTU enamel powder. After implementing this powder alongside strict production process control and quality inspection, the defect rate significantly decreased to below 3%. Both the aesthetic quality and intrinsic performance of the products improved markedly, enhancing their market competitiveness.
