Description

Thermoplastics, thermosets, or fibrous coatings all have low levels of polar functional groups on the surface and have poor adhesion properties, making it difficult to apply other functional layers such as inks, adhesives, and coatings. This paper discusses current atmospheric surface activation systems, appropriate measurements of adhesion, over-treatment effects and surface analysis techniques relative to optimizing the adhesion of inkjet inks, coatings and adhesives to these polymer and fibrous surfaces. Recommendations for improved activation by substrate are discussed.
