| Résumé : |
Grafting of maleic anhydride onto low molecular weight guayule rubber, followed by chlorination of the residual double bonds provides a powder reactive to alcohols, amines, and epoxides. 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. |
