Alcohol Soluble Polyamide Resins

Polyamide resins are made by condensation reaction of dimeric acid and diamine. Depending on the solvent polyamide resin is usually divided into co-solvent type and alcohol soluble type.

Excellent ester resistance and solubility in ethanol or alcohol mixes are both characteristics of alcohol-soluble polyamide resins. Compared to co-solvent polyamide resins or alcohol-reduced polyamide resins, these polyamide resins are typically more compatible with nitrocellulose fibers and have superior resilience to low-temperature gelation and recovery. High heat resistance printing inks can now be utilized for heat sealing thanks to enhanced compatibility with nitrocellulose.

Alcohol Soluble Polyamide Resins

Applications

Alcohol-soluble polyamide resins are used in the manufacture of gravure plastic printing inks and paper inks. They have good adhesion to polyethylene and other substrates and are particularly suitable for printing on plastic films such as polyethylene packaging films and metal foil laminates. The ink made of alcohol-soluble polyamide resin has good adhesion, high gloss, low freezing point, solvent release and good compatibility with nitrocellulose, etc.
