CAS No.: 63428-84-2
Appearance: Light yellow to yellow solid particles
Grades: HH-PA21 and HH-PA21C
Application: Alcohol-soluble flexographic inks for selected plastic films and gravure inks for paper
Packing: 25 kg net per paper-plastic laminated bag
Alcohol-soluble polyamide resin is a solid polyamide resin developed for compatible alcohol-containing printing ink systems. It provides good alcohol solubility and film-forming performance for flexographic inks on selected plastic films and gravure inks for paper.
Hanghui offers two grades: HH-PA21 for general alcohol-soluble systems and HH-PA21C for applications requiring improved low-temperature solution stability. Final suitability should be confirmed in the customer's complete ink formulation.
