Foundry binder of epoxy resin, acrylated polyisocyanate and acrylic monomer and/or polymer; and cold-box process

Described is a foundry binder addressing the problems of reduced flowability leading to reduced strength. The binder provides prolonged benchlife leading to higher tensile strength. The binder is produced from (a) an epoxy resin, (b) an acrylated polyisocyanate, (c) an acrylic monomer and/or polymer...

Beschreibung
Zusammenfassung:	Described is a foundry binder addressing the problems of reduced flowability leading to reduced strength. The binder provides prolonged benchlife leading to higher tensile strength. The binder is produced from (a) an epoxy resin, (b) an acrylated polyisocyanate, (c) an acrylic monomer and/or polymer and (d) an oxidizing agent. The binder is mixed with foundry aggregate and cured with a gaseous amine via a cold-box process to obtain a foundry shape useful as a mold for casting a metal article.
