"SUBSTRATOS TERMOPLáSTICOS DE HIDROCARBONETOS SATURADOS AMORFOS DE ADERêNCIA MELHORADA". A presente invenção é um substrato termoplástico de hidrocarboneto saturado amorfo tendo propriedades de aderência melhorada, onde as propriedades de aderência melhorada são obtidas por tratar a superfície do substrato termoplástico de hidrocarboneto saturado amorfo com uma técnica de fase de gás excitada, de modo a se obter uma energia superficial crítica de pelo menos 35 dina/cm, sem usar ácidos ou outros materiais corrosivos que degradam o equipamento. The present invention is an amorphous saturated hydrocarbon thermoplastic substrate having enhanced adhesion properties, wherein the enhanced adhesion properties are obtained by treating the surface of the amorphous saturated hydrocarbon thermoplastic substrate with an excited gas phase technique, such that a critical surface energy of at least 35 dyne/cm is obtained without the use of acids or other corrosive materials which cause equipment degradation.
