"Hydrogen Technology x 25 Years of Flame Retardant Patented Technology Merged" Next-Generation "Environmentally Friendly, Non-Combustible Water-Based Paint" Development Project Launched

Hydrogen Technology Inc. (Headquarters: Chiyoda-ku, Tokyo, Representative Director: Yasuhiro Yamamoto) and KSK Co., Ltd. (Headquarters: Ayase City, Kanagawa Prefecture, Representative Director: Yasuhiro Kobayashi) have launched a development project for non-combustible water-based paint (flame retardant water-based paint) that effectively utilizes by-products generated in the hydrogen production process. Full-scale sample manufacturing has already begun, and we will promote the mass production of innovative materials that achieve both high non-combustible and flame-retardant performance while significantly reducing CO2 emissions during the production of main raw materials compared to conventional methods.

■ Background of Development - Challenging a Complete Resource Circulation Model -

In the hydrogen production process, "water glass (sodium silicate)" and "sodium aluminate aqueous solution," which are the main raw materials for flame retardants, are generated as by-products. Conventionally, these were generally manufactured and procured through new chemical processes. In this project, through the technological cooperation of both companies, we aim to establish a "complete resource circulation model" that upcycles these by-products directly as a compounding liquid for flame retardants.

■ Three Features of This Project

(1) Contribution to Scope 3 through Significant Reduction of CO2 Emissions

Compared to existing raw material procurement processes, a significant reduction in CO2 emissions related to manufacturing is expected. This will directly contribute to the reduction of supply chain emissions (Scope 3) in the construction, event, and display industries.

(2) "Non-combustible and Flame Retardant Performance" that Clears Both Fire Service Act and Building Standards Act

A "composite liquid" combining "water glass" and "sodium aluminate aqueous solution" from hydrogen production by-products is utilized as the main raw material. This paint clears both the "Building Standards Act (non-combustibility)" required for building wall and ceiling materials and the "Fire Service Act (flame retardancy)" required for curtains and sheets. It exhibits powerful non-combustible and semi-non-combustible effects on a wide variety of materials such as cardboard, plywood veneer, PP resin, PVC, and expanded polystyrene, achieving flame retardant performance that clears the strictest certifications under domestic public standards.

(3) Integration with KSK's Patented Technology and 25 Years of Achievements

KSK Co., Ltd. is a specialized company with over 25 years of experience in flame retardant processing, certified as a Fire and Disaster Management Agency flame retardant labeler (registration number B-⑭-1231), and awarded the Chairman's Prize by the Japan Flame Retardant Association in 2022. By integrating the company's patent-pending non-combustible water-based paint technology (such as KS Retardant) with hydrogen production by-products, we will promote the development of innovative next-generation flame retardant materials.

■ Market Background and Future Outlook

The Japanese flame retardant market is projected to expand from approximately 100 billion yen in 2025 to approximately 140 billion yen in 2034 (annual average growth rate of 3.71%), driven by strengthened environmental regulations and the shift to non-halogenated substances. There is a growing need for safe and environmentally friendly fire protection solutions in a wide range of industrial fields, including construction and electronics.

In this project, after verifying its effectiveness and expanding market recognition, we plan to transition to a mass production and supply system primarily targeting major general contractors and commercial facilities promoting SDGs management. We aim to establish new industry standards in the flame retardant market and secure a solid share in this growing market, leveraging the added value of a "circular model utilizing hydrogen production by-products" as our strength.
