The curative (C) is a nitrogenous phenol resin, preferably a cocondensate resin formed among phenol, guanamine and aldehyde compounds, still preferably a phenol resin containing phosphorus and nitrogen atoms. It is also possible to use a curative comprising a combination of (C-1) the cocondensate resin with (C-2) a reactive phosphoric ester.</p> |
