Title: Innovations of David E Kramm
Introduction
David E Kramm is a notable inventor based in Laurel, MD (US). He has made significant contributions to the field of radiation curable compositions, holding a total of five patents. His work has advanced the understanding and application of thixotropic agents and flame retardant materials.
Latest Patents
One of Kramm's latest patents is focused on a radiation curable, ethylenically unsaturated thixotropic agent. This invention relates to an ethylenically unsaturated reactive thixotropic agent for use in radiation curable compositions, such as overprint varnishes. The agent is formed by reacting a hydroxyl-containing fatty acid ester with an ethylenically unsaturated isocyanate. It not only performs its thixotropic function in the uncured state but also becomes part of the cured product upon exposure to radiation, such as UV radiation, due to its similar reactivity. Another significant patent is directed towards flame retardant mercaptocarboxylic acid esters of halogenated polyols. This invention introduces novel halogen-containing polythiols that enhance flame retardancy in radiation cured thiol-ene compositions.
