Problem: Off-line coating or film lamination not adhering to primer coating

 

Solutions:

Lack Of Adhesion

• Check Dyne levels (surface tension) of the aqueous primer coating, ink, and substrate (independently and together). The Dyne level for aqueous primer coating needs to be compatible with Dyne levels for ink, substrates and off-line coatings.
• Use the least amount of coating possible to minimize coating weight.

Incorrect Coating Used

• Consult Nicoat about the proper aqueous coating primer to be used.

Additives In Ink

• Use inks with little or no additives. For example, silicones or waxes such as PTFE (Teflon), Carnauba, EBS (Ethylene bisstearamide), Fischer-Tropsch (methylene), paraffin, or microcrystalline.
