Influence of Magnetic Particles and Magnetic Field on Gloss in UV Coating

UV-curable coatings possess numerous advantages, including high production rate, low environmental impact, and customizability, making them highly appealing for a wide range of applications. However, one the greatest challenges in coating is achieving an optimal low-gloss surface by adding matting agents to formulation. Therefore, it essential find suitable agent type efficient roughness creation method tailor gloss generate controlled surface. In this study, modified magnetic particles were added formulation as agents, UV curing process was conducted under field 10 100 mT. The combined effect during on coatings’ investigated. impact modification, dispersion, concentration force final assessed. Moreover, dispersion photopolymerization evaluated. result indicated that both modification roughness. A CI-APTES 5% wt. sample cured 60 mT led highest decrease 20° gloss.
