Our "water-soluble phenolic resin" enables hydrophilization of the film surface by utilizing its high adhesion to polyamides, polyesters, and cellulose.
Our water-soluble phenolic resin demonstrates high robustness due to the hydrogen bonding strength between the hydroxyl groups of DHDPS and the carbonyl and amino groups of the aromatic polyamide film, in addition to the crosslinking utilizing the methylol groups at the ends of the resol-type water-soluble phenolic resin. After chlorination of the aromatic polyamide film, surface treatment with water-soluble phenolic resin allows the resin to adhere to the film, improving the blocking rate of hardness components in water. *Please feel free to download the catalog or contact us for more information.*
