| 摘要 |
A curable liquid composition, such as an alkyd paint or resin, contains a binder curable by oxidative crosslinking, a siccative compound for catalysing oxidative crosslinking of the binder, and a matting agent. The matting agent is a precipitated silica, with a surface area, measured by BET, of 250 m2/g or less, a precipitated metal silicate such as Ca, Mg or Al silicate, or a mixture, and may be amorphous in nature. The siccative compound is a transition metal chelate complex comprising a ligand, such as an iron- or a manganese-based chelate complex.;The compositions are capable of oxidative curing, within acceptable times, to form a cured solid, such as a coating, having a matt finish. |

1. A curable liquid composition comprising:
a) a binder curable by oxidative crosslinking, b) a siccative compound adapted to catalyse oxidative crosslinking of the binder, and c) a matting agent,characterised in that the siccative compound is a transition metal chelate complex comprising a ligand, andthe matting agent is:
a precipitated silica having a surface area of 250 m2/g or less, preferably 200 m2/g or less, as measured by BET, a precipitated metal silicate, or a mixture thereof. |
