In March 2026, the Chemiknow platform released a special solution for improving the water and boiling water resistance of paint films. Aiming at the frequent problems such as film peeling, blistering and discoloration in the coating fields of automobiles, home appliances and industrial equipment, it put forward practical measures from four core dimensions: adhesion, film compactness, hydrophilic and hydrophobic properties and construction defects. Insufficient adhesion is the main reason for poor boiling water resistance. Silane coupling agents can be used for metal substrates, and chlorinated polyolefin additives can be selected for plastic substrates with proper oil removal treatment. Film compactness is related to resins and curing agents. High-temperature baking paint has better compactness than room-temperature self-drying paint, and bisphenol F epoxy performs better than bisphenol A epoxy. Hydrophilic groups in water-based paints and the selection of additives in solvent-based paints both affect water resistance, and hydrophobic curing agents have more advantages. In construction, micro-bubbles should be avoided by adjusting defoaming additives to improve film compactness. This solution provides a comprehensive technical reference for the coating industry to optimize product quality.
