ADCOTETM 76H5 Primer 

Description

Adcote 76H5 is a clear, non-blocking primer or coating for polyester film which is suitable for use as a 

printing and coating primer for solvent, or water based inks and coating materials. It will also function as an

extrusion primer and is used as a surface coating on metallized polyester film.

Instructions for Handling

Weigh out the desired amount of Adcote 76H5. Add sufficient solvent to approximate final desired solids and 

mix thoroughly preferably with mechanical agitation. Then add desired amount of coreactant and mix

thoroughly. Adjust with solvent for desired final solids or viscosity. Use of coreactant is for increasing

resistance properties, e.g., as a two component extrusion primer. Adcote 76H5 should be evaluated without

coreactant as this is normally sufficient for use as a print primer. 

Caution

Adcote 76H5 may show a tendency to gel on exposure to cold temperatures. This can be covered by

warming to approximately 38°C (100°F) and stirring thoroughly with a high shear mechanical agitation. This

is strictly a physical phenomenon and has no bearing on final performance. 

Apply with a gravure cylinder or roll coat applicator. A dry coating weight of 0.5 pounds/3000 square feet is

suggested for priming applications. Pass through a drying tunnel sufficient to remove all solvents and then

over chill rolls to bring temperature to 33°C (90°F) or lower before rewinding. 

Full adhesion to film should develop in 24-48 hours. Extrusion coating and water based coating should be

carried out within this period for best performance. Solvent based inks and coatings can generally be applied 

for extended periods. We suggest that the customer check with his own materials for extent of primer

usefulness.

Lower coating weights begin to show iridescence or slight bloom in the coated stock due to light diffraction.

Print primers are generally applied at 0.6 lb/ream.

PACKAGING AND

CONVERTING 
Coreactant 9H1H is recommended where long term resistance to UV discoloration is required.
