| 184 | "NO-BAKE" FOUNDRY MIX WITH EXTENDED WORK TIME | US14406092 | 2013-06-07 | US20150114589A1 | 2015-04-30 | Michael R. Nocera; Gregory P. Sturtz; Jörg Kroker |
| A “no-bake” process allows the forming of larger metal castings, by providing longer work times, in the range of about 45 to about 60 minutes. This is achieved using a liquid curing catalyst that is a pyridine, substituted at the second or third position with a moiety having a molecular weight in the range of about 30 to about 100 mwu. Examples of the liquid curing catalyst include 2-ethanolpyridine, 3-chloropyridine and 2-methoxypyridine. When combined with a two-part polyurethane binder precursor and a foundry aggregate, the liquid curing catalyst provides not only the longer work time, but also a strip time that is less than about 167% of the work time, as measured from the point of activating the polyurethane precursors by mixing them in the presence of the curing catalyst. | ||||||
