The revolution of vehicle interior decoration, to display the dual curing fascination behind the piano black finish
Based on the superior texture’s pursuing and personal display, piano black finish has long been a favorite of designers for its depth, mystery and high-end feel. However, under traditional craftsmanship, the manufacturing process of a piano black interior with complex patterns, partial light transmission or color embellishment is often full of challenges: low efficiency, high energy consumption, high environmental pressure, and delicate laser engraving patterns are easily damaged during subsequent spraying. Today, a coating revolution led by UV light and heat dual curing technology is completely changing this situation.
Outstanding crafted, efficient: a complete explanation of dual-curing piano black coating
Modern high-end car interior piano black coating is far from being as simple as spraying black. It is an art that combines precision design and cutting-edge materials:
- Creative starting point: According to the function (such as light-transmitting indicators, brand logo) or aesthetic requirements, the substrate (such as plastic parts) is carefully screen-printed or pad-printed in specific areas to form different colors of underlying patterns.
- Deep base:Evenly spray high-qualityPU black primer to lay the foundation for the deep and full base color of piano black. After it is fully cured, a stable coating is formed.
- Dance of light and shadow - laser engraving: In the position where the underlying pattern or the substrate itself needs to be revealed, the cured PU black primer islaser engraved using a precision laser. The laser accurately etches away the black coating, revealing the pre-printed color pattern or the original texture of the substrate, forming a delicate visual effect.
- Peak protection:Finally, spray the key protective layer and gloss-responsible-UV light and heat dual-curing varnish. This layer is the secret to achieving both high efficiency and performance.
