| Applications | Uses: Used as a curing agent for cold-box sand molding in foundries, in the polymerization of polyamides, as intermediate for quaternary ammonium compounds, and as stabilizer for chlorinated hydrocarbons and vinyl derivatives, [HSDB] Used to make other chemicals, [CAMEO], Molding and Core Making [Category: Foundry], AS CURING CATALYST FOR RESIN BONDING OF SAND CORES, Dimethylethylamine is used in the production of mold cores in gray-iron and aluminum casting foundries and in the polymerization of polyamides., Intermediate in the manufacturing of quaternary ammonium compounds ... stabilizer for chlorinated hydrocarbons and vinyl derivatives., U.S. Production: 2023: <50, 000 lb, 2022: <50, 2021: 50, 000 - <250, 2020: 50, Production volumes for non-confidential chemicals reported under the Inventory Update Rule. [Table#5522], This chemical is listed as a High Production Volume (HPV) (65FR81686). Chemicals listed as HPV were produced in or imported into the U.S. in >1 million pounds in 1990 and, or 1994. The HPV list is based on the 1990 Inventory Update Rule. (IUR) (40 CFR part 710 subpart B, 51FR21438)., In 1977, the United States produced less that 1, 000 pounds of DMEA, but it imported an estimated 1.2 to 12 million pounds., U.S. Imports: In 1977, 000 pounds of N, N-dimethylethylamine, General Manufacturing Information: Ethanamine, N, N-dimethyl-: ACTIVE, N-Dimethylethylamine is used, in the production of mold cores, under pressure as a gas catalyst in the coremaking operation. The cores are solid reproductions of the hollow spaces desired within the finished castings. They are made from a mixture of silica sand or other aggregates, liquid phenolic resin, and a diisocyanate in a corebox machine (Isocure process). This mixture is cured in the corebox machine by a 1, 2- to 3-second exposure to N, N-dimethylethylamine. Dry air is then blown through the core to purge any remaining N, N-dimethylethylamine. After the solidified cores are manually removed from the corebox, they are either placed on storage racks or they are assembled directly. Core finishers usually work adjacent to several of the core machines and perform many intricate manual tasks to finish and assemble the cores. From the coreroom, the finished cores are sent to the mold floor, where they are placed in molds before the molten metal is poured. |
