Binder Formulations Utilizing Furanic Components

Technology Marketing SummaryThis technology describes the use of furanic components derived from agricultural waste streams, such as hydroxylmethylfurfural (HMF).  When used in combination with a phenolic urethane resin and cured with a gaseous amine catalyst, the resulting composite shapes are instantaneously cured and can be used for various applications. A primary use of these binders is in preparing foundry molds for the casting of various metal parts.DescriptionBroadly, the invention provides for a cold-box aggregate binder typically being a mixture of phenolic or urea resin and a furanic material selected from one or more of the group consisting of:

 

• 5-hydroxymethyl furfural (HMF);
• 2,5-furan dimethylol (FDM);
• 2,5-furan dicarboxylic acid (FDCA);
• 2,5-diformyl furan (DFF);
• FDCA monoalkyl ester (hemiester);
• FDM-ether; and
• HMF-ether;
• that cures in the presence of a catalyst gas

 

Benefits• Cost advantages include reduced raw material costs and increased productivity based on high available volumes of fructose, which is the starting material for HMF
• Primary performance advantages are increased core strength, further reduction of individual unit costs, and rapid decomposition properties to aid core removal from metal castings
• Quality advantages include reduced resin usage, cleaner running tooling, reduced downtime, and reproducible quality parts

 

 

Applications and Industries• Foundry cold-box process - mass production of cores and molds.
• Potential expansion into adhesive applicationsPatents and Patent Applications
