Commonly used types of easy-to-adhere coatings on PET surfaces are as follows:
Fluorocarbon coating: Fluorocarbon coating has good water resistance, chemical resistance and weather resistance, and is a common choice for easy adhesion coating on PET surface.
Fluorocarbon resin coating
Acrylic coating: Acrylic coating has good water resistance, chemical resistance and weather resistance, and is also a common easy-to-adhere coating on PET surface.
Acrylic paint
Silicon modified coating: Silicon modified coating has good water resistance, chemical resistance and weather resistance, and also has certain hydrophobicity, which can improve the adhesion between PET surface and UV ink.
Silicon modified coating
The specific type of coating to be selected needs to be determined according to the specific application requirements. For example, if the PET surface is required to have good water resistance and weather resistance, fluorocarbon coating or acrylic coating can be selected. If PET surface is required to have good hydrophobicity, silicon modified coating can be selected.
The following points should be paid attention to when coating the surface of PET with sticky paint:
The thickness of the coating should be uniform to ensure good adhesion.
The curing time of the coating should meet the requirements to ensure the performance of the coating.
The coating should have good compatibility with UV ink to ensure the printing effect.
