PROCESS FOR PREPARING EROSION RESISTANT FOUNDRY SHAPES WITH AN EPOXY-ACRYLATE COLD-BOX BINDER |
摘要 |
This invention relates to a process for making foundry shapes (e.g. cores and molds) using epoxy-acrylate cold-box binders containing an oxidizing agent and elevated levels of an organofunctional silane, which are cured in the presence of sulfur dioxide, and to a process for casting metals using the foundry shapes. The metal parts have fewer casting defects because the foundry shapes made with the binder are more resistant to erosion. |
