| CASAMID 831 |
 |
CASAMID 831 is a co-solvent thermoplastic polyamide resin designed for use in gravure inks and lacquers.
CASAMID 831 is the highest viscosity grade of the standard range of CASAMID non-reactive polyamide resins.
The composition of CASAMID 831 is similar to that approved under FDA 175.320-"Resinous and polymeric coatings for polyolefin films."
CASAMID 831 exhibits the properties of the traditional co-solvent group of resins with poor resistance to gelation and low tolerance to polar solvents but excellent solvent release and good lay.
Incorporation of phenolic resin will improve the performance characteristics of the resulting inks or lacquers.
For optimum solubility, blends of alcohols and hydrocarbons are recommended. |
