Global White Solder Mask Ink for LED Market Strategic Research Report

Scope of the Report

The global White Solder Mask Ink for LED market size is predicted to grow from US$ 184 million in 2025 to US$ 269 million in 2032; it is expected to grow at a CAGR of 5.6% from 2026 to 2032.

In 2025, global sales volume of White Solder Mask Ink for LED was approximately 12,550 tons, with a mainstream ex-factory average price of around USD 15/kg. The gross margin of major manufacturers in the industry was approximately 30%–45%.

White Solder Mask Ink for LED is a white functional solder mask ink used on the surface of LED circuit boards, and is also commonly referred to in the industry as “LED white ink.” Its main function is to form a white insulating protective layer on the PCB surface, preventing solder bridging and circuit oxidation during soldering, while improving LED light output efficiency through its high white reflectance. Compared with conventional green solder mask ink, White Solder Mask Ink for LED places greater emphasis on whiteness, reflectance, heat resistance, yellowing resistance, adhesion, and long-term light stability. It is commonly used in LED lighting, LED backlight, and other LED module circuit boards.

The upstream raw materials for White Solder Mask Ink for LED mainly include photosensitive resin, epoxy resin, acrylic resin, titanium dioxide, photoinitiator, curing agent, filler, solvent, and additive. Titanium dioxide determines whiteness and reflectance, while the resin system affects adhesion, heat resistance, and developability. The midstream segment involves ink formulation development, dispersion and grinding, mixing and compounding, filtration, packaging, and quality inspection. Manufacturers need to adjust formulations according to different substrates, such as aluminum substrate, rigid PCB, and flexible PCB. Downstream customers mainly include LED circuit board manufacturers and LED packaging and module manufacturers, with terminal applications mainly covering LED lighting, LED backlight, and other LED application.

Global key White Solder Mask Ink for LED players cover TAIYO INK, TAMURA, Electra Polymers, Sun Chemical, Lackwerke Peters, etc.
