Coattec

What Coattec does

Coattec (株式会社コートテック) is a privately held Japanese specialty chemical and coatings company founded in October 2003 and headquartered in Yokohama (Tsuzuki-ku). The company develops, customizes, manufactures, and sells UV-curable paints and proprietary portable UV irradiation equipment, and operates a UV coating service business. Its core technology is photopolymerization-based UV curing, in which UV resin formulations harden in seconds upon exposure to UV light (primarily 365nm wavelength from metal halide or high-pressure mercury lamps). Coattec has developed a portfolio of UV paints for wood, metal, FRP, ceramic, ABS, polycarbonate, and flooring substrates, with hardness ratings ranging from 2H to 6H and F☆☆☆☆ formaldehyde certification meeting Japan's sick house regulations. Its proprietary Handy UV Light devices (MD-W1000, CT-W1200, HG-W1000, CT-W100) bring factory-grade UV curing to field applications, with downsized power units (1.5kg–3.9kg) that are differentiated from conventional ballast-based systems.

The company serves four primary user segments: residential real estate developers and housing manufacturers (pre-move-in floor coating for condominiums and detached houses), commercial retail and food service operators (no-wax floor maintenance), unit bath renovation contractors (bathtub topcoating), and furniture and interior manufacturers (custom fittings, wall panels, counters). It also serves public institutions, schools, and kindergartens requiring solvent-free, F☆☆☆☆-certified coatings. Coattec earns revenue through four streams: UV paint product sales, UV irradiation equipment sales (with installment financing through Orient Corporation), direct UV coating painting service contracts with construction companies and furniture manufacturers, and a partner program that recruits construction agents, applicator contractors, and sales agents across the Kanto region (Kanagawa, Tokyo, Chiba, Saitama) with full technical know-how transfer. The company is led by Representative Director Sakuma Takeshi (咲間 毅), has 1–10 employees, ¥10M in paid-in capital, and is currently establishing a Thailand subsidiary for overseas expansion.

Revenue model

1. UV Paint Development, Manufacturing and Sales: Coattec develops, customizes, manufactures and sells UV paints for various applications including wood/metal, bathroom/FRP, flooring, automotive, and modeling. Paints are sold to construction companies, applicator contractors, and furniture manufacturers. Revenue is generated through product sales of formulated UV resin coatings.
2. UV Irradiation Equipment Sales: Sale of portable UV irradiation devices (Handy UV Lights) to partners and contractors. Models include MD-W1000, HG-W1000, CT-W100, and CT-W1200. Equipment sales represent an upfront hardware revenue stream. Credit installment payment is available through Orient Corporation (up to 36 installments).
3. UV Coating Construction Services: Direct painting service contracts for UV coating of custom furniture, fittings, wall panels, floor boards, office counters, and other surfaces. Coattec accepts orders from construction companies, applicator companies, and furniture manufacturers. Revenue is project-based.
4. UV Coating System Partnership (Technology Licensing/know-how transfer): Coattec provides complete UV coating system know-how and technology transfer to partners (construction agents, applicators, sales agents). Partners purchase Handy UV Lights and UV paints and receive full technical training, guidance, and aftersales support. This creates recurring hardware and consumable (paint) revenue streams from the partner network.

Broad incumbents

• Axalta Coating Systems: Global coatings company specializing in liquid and powder coatings for industrial and refinish markets. Comparable as an industrial coatings supplier, though Axalta's scale and automotive/refinish focus differ from Coattec's niche on-site UV applications.
• PPG Industries: Global industrial and architectural coatings manufacturer with UV-curable product lines. Comparable in UV coatings chemistry, though PPG's portfolio spans aerospace, automotive, and industrial at global scale rather than on-site specialty applications.
• Kansai Paint: Major Japanese and global paint manufacturer serving automotive, industrial, decorative, and protective coatings markets. Comparable in industrial coatings product overlap, but with much broader portfolio and global distribution that Coattec lacks.
• Toagosei: Japanese specialty chemicals company producing acrylic esters, adhesives, and specialty coatings including UV-curable formulations. Comparable in UV resin chemistry and specialty coatings, though Toagosei is a diversified chemicals manufacturer with broader product lines.
• Specialty Coating Systems (SCS): Global leader in Parylene conformal coatings and UV-curable coatings for electronics, medical, and industrial applications. Comparable in UV-curable coating technology and specialty formulations, though focused on electronics and medical rather than architectural/industrial surfaces.
• Nippon Paint Holdings: Asia's largest paint manufacturer with extensive decorative, automotive, and industrial coating lines. Comparable in industrial coatings broadly, with UV technology present in their portfolio, but with massive distribution and scale advantages over Coattec.
• Dai Nippon Toryo: Japan's largest domestic paint manufacturer with broad industrial, architectural, and specialty coating lines. Comparable as a competitor in industrial and protective coatings, though Dai Nippon Toryo operates at vastly larger scale and across many coating chemistries, not specialized in UV.

Direct peers

• IGM Resins (Specialty UV Curable Resins): Global specialty chemical supplier of photoinitiators, UV-curable resins, and additives used in UV coatings, inks, and adhesives. Comparable as a UV resin chemistry specialist, though IGM is a raw materials supplier rather than a finished-coating system provider like Coattec.
• Musashi Paint Co. Japanese specialty coatings manufacturer focused on industrial paints and coatings, including UV-curable products. Comparable as a Japanese specialty coatings company competing for similar industrial customers, though with broader product range.

Regional players

• Berger Paints Japan / Nippon Berger: Asia-focused paint brand with operations relevant to Japanese industrial and architectural coatings markets. Comparable in industrial coating chemistry, though the broader Berger group operates across India and Asia rather than competing directly with Coattec's niche on-site UV model in Japan.
