Abstract

Aminoplast resins are cured using inorganic particles as curing agents. The inorganic particles have a laminated structure and include interlamellarly exchangeable cations such as alkali cations, alkaline-earth cations, aluminum cations, iron cations and/or manganese cations. The aminoplast resins may be cured to produce semi-finished products and molding materials.
