CA 1335683

A composite tooling part having excellent dimensional stability, which may be prepared at low cost employs a one-component epoxy resin system having a catalyst which is the reaction product of an aromatic dicyanate and an imidazole. Reinforcing materials are incorporated in the matrix, and the resulting prepreg is allowed to cure at low temperature, down to about room temperature, until the free standing state is obtained. Thereafter, if elevated temperature performance is necessary, the product can be post-cured at elevated temperatures, without the need for a high temperature master.
