PU1293-1 is a Shading Stain developed for musical instrument finishing. Featuring full hiding power, it delivers uniform solid black appearance and covers wood substrate completely, serving as a colour base layer before topcoat application. Optimised for mass‑production instrument workshops and professional luthiers.

PU1293-1 has good interlayer adhesion and stable coloring, but a transparent topcoat is still needed for protection after the coloring layer.

The PU Sealing Primer Series is a line of products specifically designed for use as a primer before applying the topcoat, and is typically formulated from polyurethane (PU) resin. PU12A has excellent adhesion, filling, sealing, durability, chemical resistance, and moisture resistance, making it an ideal primer for high-end wooden musical instruments such as guitars, ukuleles, and violins.

PU (Polyurethane) Coating forms an exceptionally resilient surface film that delivers outstanding scratch and impact resistance.

The polyester coating generally refers to the polyester formed by the polycondensation reaction of polybasic acid and polyol (including partially unsaturated polybasic acid) and then mixed with a comonomer, which is crosslinked and cured under the action of initiator and accelerator to form a coating film. Coatings are customarily called polyester coatings

Polyester paints for pianos are particularly scratch-resistant, making wood surfaces retain their gloss for decades.

The coatings not only protect wood instruments of any style, but can also be used for high-quality interior woodwork designs on artwork or stores.
