NB80 is an adhesion promoter that may be added to certain Nazdar inks to improve adhesion to plastics and some coated metals. To achieve optimum adhesion results on polyolefins, i.e. corrugated polypropylene; it is recommended that the surface tension test above 44 dynes/cm. NB80 may be added to the following inks: Plastic Plus, 8400 9600, 9700, and all Nazdar UV curable inks.

AMOUNT Solvent Inks: Add up 10% by weight and mix thoroughly. UV Inks: Add up to 5% by weight and mix thoroughly. Refer to each ink series technical data sheet for specific recommendations.

POT LIFE Pot life of ink/catalyst mixture is dependent on the amount of NB80 used. UV inks with 5% NB80, and solvent inks with 10% NB80 have an expected pot life of 6 – 8 hours. Halftone inks will have a shorter pot life, normally 2 – 3 hours.

CURING Refer to each ink system’s technical data sheet for recommended cure parameters. Note: Improved adhesion will be demonstrated within 24 hours. The NB80 may continue to react, improving ink film properties over the next several days.
