Chlorinated maleinized guayule rubber as an adhesion promoter for polypropylene / Michael. D. Foster in JOURNAL OF COATINGS TECHNOLOGY (JCT), Vol. 71, N° 889 (02/1999)
[article]
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.

The product, chlorinated-maleinized guayule rubber (CMGR), is a potential crosslinker/additive for powder coating formulations. Accordingly, polyester-hydroxyalkyl-amide and epoxy-polyester hybrid powder coating formulations were developed, applied, tested, and contrasted to properties of commercial powder coating formulations. The coatings featured reduced gloss, surface texturing, and physical property characteristics equal to or exceeding those derived from commercial powder coating formulations. Thus, CMGR is a promising reactive crosslinker for powder coatings.
