Latest Patents

Penczek's latest innovations include the following patents:

1. **Cresol-free or low-cresol wire enamels** - This invention pertains to wire enamels utilizing polyester, polyesterimide, polyesteramidoimide, and/or polyurethane resins, which serve as binders. The formulation is notable for containing organic solvents, wherein at least 50% by weight consists of a monocyclic aromatic alkyl-carboxylic acid ester or isophorone, or a blend of methyl benzoate and isophorone.

2. **Method for making polyesterimide varnishes** - This patent outlines a method for producing polyesterimide varnishes through the polycondensation and imidization of a mixture inclusive of trimellitic anhydride, 4,4'-diamino-diphenyl methane, glycol, dimethyl terephthalate, and glycerol or tris(hydroxyethyl) isocyanurate. The process is enhanced with the addition of a transesterification catalyst and results in the dissolution of the polyesterimide resin in an organic solvent along with a crosslinking catalyst. A distinctive feature of this method is the use of 2-methyl-1,3-propanediol and/or 2-butyl-2-ethyl-1,3-propanediol as glycols.
