Cationic binder materials (such as polyester with high adhesion).

Our water-soluble phenolic resin demonstrates high adhesion even to substrates without bonding agents, such as polyester and cellulose.

We would like to introduce "cationic binder" as an application example of water-soluble phenolic resin from Kohnishi Chemical Industry Co., Ltd. We have found that water-soluble phenolic resins exhibit high adhesion even to substrates without bonding groups, such as polyester and cellulose. In addition to the hydrogen bonding strength between the hydroxyl groups of DHDPS and the carbonyl or hydroxyl groups of the substrate, the crosslinking (thermosetting) utilizing the methylol group at the end of the resol-type water-soluble phenolic resin demonstrates high robustness. 【Features】 - Optimization of the molar ratio and molecular weight of DHDPS and sulfonic compounds - High adhesion to substrates without bonding groups - High robustness *For more details, please refer to the PDF document or feel free to contact us.
