PE Piano-Grade Coating Elevates Musical Instrument Aesthetics

A renowned Asian musical instrument maker (focused on pianos and acoustic guitars) chose DOIT’s PE piano-grade coating series in 2025 to upgrade its product appearance. The client needed a high-gloss, mirror-like finish (glossiness ≥95%) with excellent yellowing resistance. DOIT’s PE piano Glossy Black Paint (high-hardness) met this demand: it achieves a polished effect without post-polishing, saving 30% of processing time, and its yellowing resistance grade (≥3.5) ensures the instrument’s surface retains its luster for 5+ years. For guitar bodies, DOIT customized a PE transparent primer that enhances mahogany grain while preventing moisture damage. The partnership has since expanded to 500 tons/year, with the client noting, “DOIT’s coatings have become a key selling point for our high-end instruments.”
