Latest Patents

Waldman's most recent patent is titled "Curable silane-encapped compositions having improved performances." This invention focuses on certain members of the class of N-silylalkyl-aspartic acid esters, which, when used to endcap polyurethane polymers, provide moisture curable, one-part sealant formulations. These formulations exhibit significantly improved physical properties compared to other organofunctional silanes. Specifically, polyurethane polymers terminated with dibutyl or diethyl maleate/primary aminoalkyl silane addition products outperform comparative sealants made with other olefinic carboxylate esters or nitrile/primary aminoalkyl silane addition products. Furthermore, sealant formulations that incorporate these terminated polymers show unexpected enhancements in elongation and tensile strength performance, along with increased tear resistance.
