Santel HR-97 is a water-based primer for all grades of films which is used to improve printing adhesion and lay down properties. Certain films are difficult to print and inks may not have adequate adhesion for packaging applications. Applying Santel HR-97 to the surface of the film, prior to printing, will greatly improve ink lay down on press and final print adhesion values.

Santel HR-97 is used as supplied and can be applied with conventional coating apparatus such as gravure, flexo, roll, blade, rod, etc. Light application weights are typical but optimum weights should be determined by the user. A typical starting point would be the application of 6 pounds wet per ream (3000 square feet). After applying, the surface should be completely dry before printing. It is non-tacky and can be wound for subsequent use.

Santel HR-97 is also an excellent primer which enhances and permits adhesion of PVDC to LDPE and PVC films. It has been tested with other substrates as well and has been found to perform well.

Santel HR-97 is completely water-based and contains no organic solvents or ozone depleting chemicals.
