根上工業 List of Products and Services

This product is suitable for use as a binder in paints and inks, as well as ceramic binders. Since it is manufactured using our company's strength in "water-based suspension polymerization," it offers: - High molecular weight: Mw 10,000 to 1,000,000 - No use of emulsifiers or coagulants; low levels of low molecular weight components, residual monomers, and impurities - Polymer design; copolymerization of various acrylic monomers and introduction of various functional groups - Control of glass transition temperature It is supplied in bead form. For more details, please download the catalog. We also offer free samples, web seminars, and product customization. Feel free to contact us.

- Acrylic Polymer PARACRON PR-4 (Tg=-52℃, Biomass content 68%) - Methacrylic Polymer Hi-pearl BSL-5200 (Tg=+136℃, Biomass content 35%, Ethyl acetate solution; Solid content 40wt%)

Lineup of acrylic-based polymers from Negami Industrial (1) PARACRON; low Tg flexible acrylic polymer (2) Hi-pearl; methacrylic resin (3) ART CURE; liquid acrylic polymer that can be cross-linked with UV and electron beams (4) ART PEARL; spherical cross-linked acrylic microparticles

Hi-pearl MA-4620 This is an acid-modified methacrylic resin synthesized by suspension polymerization. ART CURE MAP-7030 This is an acrylate acrylic resin that can be developed with alkaline processing. UV crosslinking is possible after development.

- It excels in the balance of chemical resistance, hardness, adhesion, and abrasion resistance. - It is provided as a polymer solution with 60% ethyl acetate. - Due to the presence of hydroxyl groups, it is suitable for two-component paint applications combined with isocyanates.

A new grade of Hi-pearl(R) has been created. - High acid value - Low molecular weight - Narrow molecular weight distribution - Methacrylic resin - Customizable Acid value, molecular weight, introduction of other functional groups, monomer copolymerization - Free samples are available.

This product is a reactive methacrylic polymer with functional groups, suitable for two-component curing type paints/inks as a main agent/hardener or for alkaline developing type resist materials. Manufactured using our strength of "water-based suspension polymerization," it has the following features: - Molecular weight control; Mw 10,000 to 1,000,000 - No use of emulsifiers or coagulants; low molecular weight components, residual monomers, and impurities are minimal - Polymer design; copolymerization of various acrylic monomers and introduction of various functional groups - Control of glass transition temperature It is supplied in bead form.
