A widely used technique for assuring paint adhesion to TPO is the use of adhesion promoter primers based on chlorinated polypropylenes (CPO). Much research has been focused on understanding the forces involved at the interfaces of substrate, adhesion promoter, and topcoats resulting in the adhesion or the loss of adhesion in various environmental conditions. This study correlates the adhesion performance of CPO and nonchlorinated adhesion promoters (NCPO) as measured by peel strength with properties observed through microscopy techniques. Adhesion performance of CPOs, NCPOs, and blends are quantified through the use of 90° and 180° peel strength studies. Surface characteristics of adhesion promoters applied over a TPO substrate and cured at various temperatures are examined through the use of atomic force microscopy (AFM).

Titre : Chlorinated maleinized guayule rubber as an adhesion promoter for polypropylene Type de document : texte imprimé Auteurs : Michael. D. Foster, Auteur ; Shelby F. Thames, Auteur Année de publication : 1999 Article en page(s) : p. 91-99 Note générale : Bibliogr. Langues : Américain (ame) Tags : 'Matériau revêtement' 'Peinture eau' Adhérence 'Matière plastique' 'Propène polymère' 'Traitement surface' 'Caoutchouc naturel' modifié' Chloration Furane-2,5-dione(2,5-dihydro) 'Promoteur adhérence' Index. décimale : 667.9 Revêtements et enduits Résumé : Chlorinated maleinized guayule rubbers (CMGR) were synthesized and applied as coatings onto polypropylene panels. CMGR orientation was critical to adhesion and was verified by contact angle measurements. Reducing the quantity of tetrahydrofuran (THF) decreased adhesion from 57 N/cm2 with pure THF to 23 N/cm2 with four percent THF in water. Percent maleinization above a critical concentration of 15 by weight decreased adhesion. However, 10% maleinization was required for dispersion stability in water while 5-10% concentration provided maximum adhesion. A five percent maleic CMGR dispersion at 240 g/L THF concentration was stable for less than 24 hr while a 10% maleic anhydride concentration has shown long-term stability.
