CP-6400 is a resin-binder copper paste that achieves high conductivity and flexibility, enabling excellent stress relaxation to help prevent cracks in electronic components. It offers migration resistance and cost advantages over silver pastes, while providing strong adhesion to external electrode layers and good compatibility with plating. The paste also demonstrates superior resistance to bleeding and stable performance under damp-heat conditions. Properties such as viscosity, storage modulus, volume resistivity, and adhesion can be adjusted to meet diverse customer needs, and it supports multiple coating and printing methods including dip coating and screen printing.

Our water-based binders for LIB uniformly disperse active materials for anode and ceramic particles for separator coating, and exhibit superior adhesion strength through control of molecular weight and functional groups. Our binder for anode contributes to achieving high-concentration slurry and longer service life by improving capacity retention of LIB compared to SBR/CMC, the conventional water-based binder. Our binder for separator demonstrates superior adhesion strength at the ceramic-separator interface, and gives heat resistance to the separator.

Pressure-sensitive adhesives provide convenient bonding at room temperature, but they typically suffer from reduced adhesion strength under high-temperature conditions. To address this issue, we have developed a novel polymerized rosin ester tackifier with a softening point of 150-165 degrees, which exhibits excellent compatibility with n-butyl acrylate-based acrylic resins. Even when added at 50 phr, the adhesive maintains good transparency. Heat-resistance testing confirmed improvements in peel strength and holding power, achieving approximately twice the performance of conventional products. This material contributes to enhanced reliability in high-temperature applications.

This coating agent, made primarily from rosin (pine resin), offers a high biomass ratio for sustainable packaging. Applied to paper, it adds barrier properties, heat-sealability, and transparency, enabling paper to go beyond its usual limitations. Compliant with major food-contact regulations, it is safe for direct contact with food. With this coating, packaging formats that paper alone cannot achieve - such as molded containers or packages with transparent windows - become possible using coated paper only. Combining eco-friendliness with advanced functionality, it provides a next-generation solution that reduces plastic use while maintaining performance and design flexibility.

Rosin, a natural resin derived from pine trees, has long been used as a medicinal ingredient for its antibacterial and anti-inflammatory properties. In this study, we synthesized candidate compounds based on mDA, a rosin-derived compound previously reported to exhibit anti-obesity activity. These candidate compounds were evaluated through in vitro assays and in vivo tests using mice. As a result, two candidate compounds demonstrated higher activity compared to mDA. Moving forward, we aim to develop applications in pharmaceuticals, dietary supplements, and functional food ingredients, with potential use for both humans and animals.
