1 of 47 products in this brand
UNI-REZ 2940 polyamide resin is a co-solvent type resin which is soluble in alcohols, but typically requires mixtures of aliphatic hydrocarbons and alcohols for gel stability. UNI-REZ 2940 polyamide resin provides fast solvent release and good grease resistance in flexographic / gravure inks for plastic substrates and is especially effective as an overprint lacquer.

Chemical Family: Polyamides

End Uses: Flexography Ink, Gravure Ink, Other Ink Types

Storage & Handling

Storage

To be stored in full, closed containers kept in a cool, dry area. Granulated forms of resin are prone to slow oxidation which may result in darkening and/or have an adverse effect on solubility after prolonged storage.
