How Prime IT can help to overcome problems with plastic films that are difficult to laminate ?
Plastic materials have inherently low wettability, mainly due to the lack of polar functional group on the surface, resulting in adhesion failure of inks, adhesives and varnishes. Ciba Speciality Chemicals have developed Ciba Prime IT, an innovative, patented technology to improve adhesion of UV-curable inks, coatings and adhesives on plastics. Adhesion of UV inks on plastics is sometimes poor, making it necessary to use physical or chemical treatments (as primers).
Compared to Prime IT, conventional chemical treatment require higher quantities of product and additional procedures, involving for example the use of solvent and/or less environmentally compatible chemicals, while physical treatments such as corona have stability problems. |
