GUANGDONG KOTTI NEW MATERIAL CO.,LTD. founded in 2009, is an enterprise specializing in the high-end field of electronic chemicals for printed circuit boards (PCB). Upholding the corporate spirit of “focus, attention to detail, execution, and efficiency,” the company aims to break the monopoly of imported products and promote domestic substitution. With the goal of advancing the high-end application of polymer materials in printed circuit boards, the company continuously invests in research and development through strategic planning and collaboration between industry, academia, and research institutions. To date, the company has obtained authorization certificates for 13 invention patents and more than 30 utility model patents. It has also been recognized as a “National High-Tech Enterprise,” “Shaoguan PCB Chemicals Technology Research Center,” and “Technology-based Small and Medium-sized Enterprise.”

The company has developed and commercialized three major product lines: PCB resin plug hole ink series, PCB solder mask plug hole ink series, and PCB surface treatment protective ink series. Among them, the full range of resin plug hole ink products—featuring high Tg, low CTE, low Dk & Df, high thermal conductivity, and low-temperature curing—are widely used in resin plug hole processes for various substrates and manufacturing technologies. These products have gained broad recognition and high praise from domestic PCB manufacturers and end customers, achieving comprehensive domestic substitution and ranking among the leading products in the Chinese market.

The PCB solder mask plug hole ink series enables a one-stage baking process without bubbles or cracks, effectively addressing the industry’s challenges of low efficiency and unstable quality in solder mask plug hole processes. These products are currently in mass production at multiple customer sites. In addition, the anti-gold plating selection ink series has developed both thermosetting and photosensitive products, offering advantages such as low organic dissolution, high resolution, and easy stripping. These products are widely used in applications including selective gold plating, electroplating gold, and gold fingers, and have received broad customer recognition.

KOTTI looks forward to cooperating with industry partners to contribute to the prosperity and development of the printed circuit board industry.
