Patent 0001354554: "SURFACE TREATMENT OF THERMOPLASTIC POLYMER MATERIAL TO IMPROVE ADHESION PROPERTIES"
Innovative solution concerning the improvement of polymer materials adhesion properties, in particular of polyolefin type.
These materials have a low surface tension, for which it is difficult to adhere any type of coating, unless resorting to particularly expensive surface treatments, such as plasma or flame treatment.
The solution developed involves affixing a glass fiber veil on the component in the molding step, which therefore does not involve subsequent processing. Glass fibers on the surface increase the number of adhesion sites, promoting adhesion which may also be better than that obtained with traditional methods.
The solution can be applied to automotive sector.
