As environmental standards have become the "entry threshold" for the interior wall coating industry, consumer demand has shifted from "environmental priority" to "user experience priority". Stain-resistant and easy-to-clean coatings have emerged as a popular choice for home decoration. This long-underestimated rigid demand, though not new, is witnessing substantial market growth driven by clear application scenarios and high repurchase potential.
Stain resistance and easy cleaning are often confused but have distinct technical boundaries: stain resistance focuses on preventing pollution adhesion through surface energy regulation and improved film density, while easy cleaning emphasizes non-destructive removal of attached contaminants. Qualified products must meet both core requirements, with their performance limits determined by three key factors: surface energy control, film cross-linking structure, and interface stability.
In formula design, the resin system is the core, functional additives only play a tuning role, and the rationality of the pigment-filler system is also indispensable. Currently, these products are widely used in high-frequency contact scenarios such as children's rooms, kitchens, and foyers, capable of preventing daily pollution adhesion and restoring appearance through ordinary cleaning, becoming a key grip for brands' differentiated competition.
