Negami Chemical Industrial Co.,Ltd. Product Lineup

This is a material that provides a UV-curable polyurethane film with an elongation exceeding 1900%. Being a solvent-free type, it is also environmentally friendly. We have free samples available. Please feel free to contact us.

It is a low molecular weight, trifunctional urethane acrylate.

This is a urethane acrylate suitable for high-frequency circuit board materials for next-generation communications such as the fifth-generation mobile communication system (5G). Since it contains an acryloyl group, it can be cross-linked with "electron beams," "ultraviolet (UV)," and "visible light," etc. *The light radical generator is a product of urethane acrylate without additives. We are currently offering free samples and product explanations on our website! Please feel free to contact us.

This is a radical reaction-type urethane acrylate that crosslinks with "electron beams," "ultraviolet rays (UV)," and "visible light." Our urethane acrylates have a rich lineup! We offer a range from high molecular weight polymers to oligomers. Thanks to our strength in high molecular weight technology (Mw 50,000) and multifunctionalization technology with acryloyl groups ranging from 2 to 15, we provide products that achieve flexible hardness settings (from rubber-like to hard coat) and functionality (stretchability, bend resistance). Please note that this product is supplied as a standalone urethane acrylate, without the addition of photoradical initiators. For more details, please download our catalog. We also offer free samples, web seminars, and product customization. Feel free to contact us.

- It is a multi-functional non-yellowing urethane acrylate. - The surface of the coating film is tack-free after solvent drying (before curing). - It has high hardness, excellent abrasion resistance, and low curing shrinkage. - A hard coat agent that is less prone to cracking can be produced.

The current lineup consists of four grades. Flexible, high elongation type: MBU-191 (biomass content 81%) Flexible type: MBU-071 (biomass content 68%) Rigid type: JHP-001 (biomass content 24%) Methacrylate type: STQI-037PR (biomass content 55%)

It complies with legal regulations in countries such as China, South Korea, Taiwan, and the United States, making overseas expansion possible.

It has excellent handling properties with low viscosity. It is suitable for optical adhesive bonding.

- Tin-free, low-crystallinity ether-based urethane acrylate with 70% biomass content. - It excels in strength and elongation. - It is suitable as an oligomer for gaskets, sealing materials, and adhesive bonding.

It has excellent handling properties with low viscosity, exhibiting flexibility, high elongation, and high tanδ.

Two types are available: WEH-1 for hard coatings and WES-1 for flexible grades. A uniform coating film can be obtained from fine particle sizes. *For more details, please refer to the PDF document or feel free to contact us.*

This product is a di-functional urethane methacrylate with a methacrylate base. It is suitable as a base resin for thermosetting adhesives, anaerobic adhesives, and sealing/casting agents. - Due to its milder reactivity compared to acrylate bases, it has low exotherm, anaerobic curing properties, and low curing shrinkage. It is also characterized by high heat resistance and low toxicity due to its high Tg. - It has a structure that combines hydrolysis resistance from the ether backbone and toughness from the aromatic component. - It uses plant-derived raw materials, making it possible to consider environmentally friendly product development. It is supplied in liquid form. Please download the catalog for more details. We also offer free samples, web seminars, and product customization. Feel free to contact us.

This product line consists of bifunctional urethane acrylates with properties such as moisture and heat resistance, heat resistance, chemical resistance, and high insulation. It is particularly suitable as a base resin for UV-curable adhesives and coatings for electronic materials. - We offer three types: polycarbonate-based, hydrogenated polybutadiene-based, and aromatic-based. - All of them form flexible and tough films with rubber elasticity after UV curing. - The polycarbonate-based type has particularly high heat resistance and high moisture and heat resistance. - The hydrogenated polybutadiene-based type has particularly low water absorption and high insulation properties. - The aromatic-based type has particularly high chemical resistance. It is supplied in liquid form. Please download the catalog for more details. We also offer free samples, web seminars, and product customization. Feel free to contact us.

This product line consists of environmentally friendly water-based UV-curable urethane acrylates, which reduce VOC (volatile organic compounds) emissions as they do not use solvents. There are various types available, from high hardness types to flexible types, tailored to different applications and formulations, making them suitable as base resins for hard coats and top coats with a low VOC concept. - We offer a lineup of fully water-soluble types, emulsion types, and cationic/anionic/nonionic types. - After UV curing, they form a high-hardness film or a flexible film with rubber elasticity. They are supplied in liquid form. Please download the catalog for more details. We also provide free samples, web seminars, and product customization. Feel free to contact us.

Recently concluded with great acclaim, at Chemical Material Japan 2025, we showcased and presented various new products at our exhibition booth. For details, please download the catalog and check it out. We also offer free samples, online briefings, and product customization. Please feel free to contact us.

The product line consists of non-yellowing, tin-free urethane acrylates with low viscosity and high flexibility characteristics. They are suitable for UV-curable adhesives and sealants, and their excellent transparency makes them ideal for optical applications. - We offer three grades with varying molecular weights and functional group numbers. - They have low viscosity and excellent handling properties. - UV curing results in flexible and high elongation mechanical properties. - With a low Tg, they maintain stable low-temperature characteristics with minimal changes in elasticity over a wide temperature range. - The three-functional type PHM-601 exhibits superior environmental resistance. - They comply with regulatory standards in various countries, primarily in East Asia. They are supplied in liquid form. Please download the catalog for more details. We also offer free samples, online briefings, and product customization. Feel free to contact us.

The product line consists of ether-based urethane acrylates with anti-fogging properties. They are suitable as UV-curable anti-fogging agents. - We offer three grades with different anti-fogging and scratch resistance by varying molecular weight and the number of functional groups. - Anti-fogging properties are exhibited through UV curing. - TX-102 is a two-functional urethane acrylate with excellent anti-fogging properties and flexibility. - TX-108PMA is a four-functional urethane acrylate with good anti-fogging and scratch resistance, providing a well-balanced performance. - NOI-045PGM is a six-functional urethane acrylate that possesses anti-fogging properties and excellent scratch resistance. - The TX Series complies with regulations in various countries, primarily in East Asia.
