In May 2026, Huabaida Platform released a summary covering ten frequent technical troubles about hand-feel development of 3C coatings based on abundant first-line formulation debugging cases, proposing standardized solutions for common production defects including cratering, post-coating tackiness and poor recoatability, making up for practical technical gaps in industrial application. The report confirms coating hand feel can be quantified by testing indicators like roughness and friction coefficient, yet manual inspection is still indispensable alongside instrumental calibration due to complicated human tactile perception. Different compatibility rules decide the selection of hand-feel additives between water-based and solvent-based coating systems. According to R&D findings, reactive hand-feel agents and high-molecular wax effectively improve the durability of surface touch. Combining inherent hand feel from resin molecular design with auxiliary additives becomes the mainstream formula design, and striking a balance among soft touch, recoating performance and anti-sticking property turns into the core of coating research.
