APPLICATIONS
This solid resin product is co-solvent soluble in variety of alcohol and Toluene for use in gravure inks. R- 210 can be formulated into inks that provide excellent cohesion, flexibility and adhesion to various polyolefin films and metal foils.
Further this non-reactive polyamide can be used in cost-reduction of Epoxy polyamide paint by addition of the same in epoxy part, it will give better gloss in paint due to better wettability of pigments in polyamide resin. It imparts good adhesion and flexibility to the system.
