Ageing effects, lead oxides

Metal oxides. Zinc oxide is the most effective metal oxide. The zinc oxide should have a low lead content. Zinc oxide has three main functions (a) promote cure (b) improves ageing, heat and weathering resistance (c) acid acceptor. In general, 2-5 phr zinc oxide is added in latex formulations. [Pg.668]

Metal oxides also act as curing agents in adhesive films. Zinc oxide is the most effective, leading to increased strength as the bond line ages. At higher levels (20-40 phr) magnesium oxide also is effective, particularly if the bond is briefly exposed to elevated temperatures. [Pg.292]

Metal Oxides. Zinc oxide is the most effective metal oxide. French-process-type zinc oxide, which is low in lead content, is incorporated into the latex as a dispersion. Zinc oxide serves three main functions (1) promotes cure (2) improves aging, heat, and... [Pg.303]
