Effect of Thermochromic and Photochromic Microcapsules on the Surface Coating Properties for Metal Substrates

A coating with thermochromic and photochromic microcapsules can enhance a product’s attractiveness. Different processes may affect the performance of coatings. Therefore, micromorphology, chemical composition, chromatic difference, gloss, hardness, adhesion, impact resistance, roughness, cold liquid ultraviolet photooxidation resistance surface on metal substrate were assessed by choosing three processes. The color difference in primer topcoat changes greatly. When temperature reached 80 °C, maximum was found to be 23.0. most obvious, 71.7. gloss mixed highest, which 81.7 GU. 15.6. mechanical property best—the hardness 2H, adhesion level 1, 12.5 kg·cm. prepared other two sequences poor. finishing had sufficient before after changed slightly.
