Core-corona type particles have a structure in which hydrophilic units are arranged radially from a core part made up of hydrophobic units. There are grades with corona parts of different ionicities, and they are stabilized in dispersion in water by the hydrophilic units on the particle surface. When core-corona type polymer microparticles are used as a binder for the anode of lithium-ion secondary batteries, they show a higher capacity retention rate and better rate characteristics compared to anodes using conventional binders. 【Features of Core-Corona Type Binders】 - Strong adhesion to the active material surface due to the functional group effects of the corona chains - Low electrode resistance - Does not swell in electrolyte - Enables the production of batteries capable of high-speed charge and discharge For more details, please contact us or download the catalog.

Our company has refined the synthesis technology of water-dispersible polymer microparticles known as "core-corona type microparticles" and is focusing on their application in the battery field. "Elevain" can be used as a binder for both the anode and cathode. It offers high design flexibility and can be used in the same way as SBR. Additionally, electrodes using core-corona type polymer microparticles as a binder demonstrated a higher capacity retention rate compared to electrodes using conventional binders. 【Features】 ■ High design flexibility ■ Usable as a binder for both anode and cathode ■ Can be used in the same way as SBR *For more details, please refer to the PDF document or feel free to contact us.

The "Senka Act Gel Series" is a W/O emulsion-type thickener that provides thickening effects with short stirring times. It does not require the addition of alkali (pH adjustment) like alkali-thickening types. As it is an easy-to-handle liquid product, it can be widely used for thickening various water-based products. There are various grades available depending on the ionic nature and pH of the target solution. 【Features】 ■ Thickening effects can be achieved with short stirring times ■ Does not clump like starch or gum when added to water ■ Lower stringiness (viscosity that pulls like a thread) compared to starch-based thickeners, showing high thixotropy ■ Capable of thickening water-based emulsions such as acrylic and vinyl acetate (e.g., paints, adhesives) ■ Senka Act Gel AP200 is suitable for neutral to strongly alkaline regions Senka Act Gel AS100 is suitable for weakly acidic to alkaline regions Senka Act Gel NS100 is suitable for weakly acidic to alkaline regions Senka Act Gel CM100 is suitable for acidic regions Senka Act Gel CD100 is suitable for strongly acidic to alkaline regions Shows high thickening effects in the above pH ranges (e.g., cleaning agents) *For more details, please refer to the PDF document or feel free to contact us.

"Senka Act Gel CM100" is a cationic thickening agent in emulsion form based on methacrylic acid esters. It is effective for thickening cationic water-based products where conventional anionic thickeners cannot be used. Additionally, because it is a liquid type that is easy to handle, it can be widely used for thickening various water-based products. 【Features】 ■ Enables thickening of cationic water-based products where conventional anionic thickeners cannot be used ■ Fast dissolution rate due to its liquid form ■ Can be directly added to the water-based products that need thickening ■ No need to add alkaline agents such as ammonia water *For more details, please refer to the PDF document or feel free to contact us.

This is an introduction to our "Functional Polymer Field." To accommodate a wide range of applications and purposes, we offer products such as the "Unisense Series," including aqueous types and chlorine-free types, as well as the "Nano Attacker Series." Based on our extensive know-how, we provide various water-soluble polymers with diverse functionalities, focusing on cationic polymers, which are our specialty. 【Product Lineup】 ■ Unisense Series - Aqueous Type - Chlorine-Free Type - Emulsion Type Functional poly(DADMAC) ■ Unisense NPP ■ Nano Attacker Series *For more details, please refer to the PDF materials or feel free to contact us.

The Unisense NPP series is an allylic cation polymer that has a branched structure within the molecule and also contains reactive groups that can undergo radical polymerization. By utilizing the reactive groups in the polymer, it becomes possible to copolymerize with other radical polymerizable monomers, which opens up possibilities for applications such as use as macromonomers and crosslinking agents. 【Contents (excerpt)】 ■Structural formula ■Usage examples ■Particle size *For more details, please refer to the PDF document or feel free to contact us.
