Title: Thomas J Podlas: Innovator in Joint Compound Technology
Introduction
Thomas J Podlas, an accomplished inventor based in Hockessin, Delaware, holds a remarkable portfolio of 12 patents. His innovative work primarily focuses on improving joint compound formulations, which are pivotal in construction and building applications.
Latest Patents
Among his latest patents, Podlas has developed a joint compound that incorporates nanocrystalline cellulose (NCC) to enhance crack resistance. This innovative joint compound is created by combining water, fillers like calcium carbonate, a latex emulsion binder, a thickening system such as methylhydroxyethyl cellulose, and nanocrystalline cellulose. The incorporation of NCC significantly reduces crack formation during the drying process, enhancing the overall durability of the joint compound.
Additionally, he has introduced a tape joint compound utilizing a carboxymethyl cellulose (CMC) thickener system. This involves using CMC with a CMC degree of substitution (CMDS) greater than or equal to 0.76, optionally combined with a non-ionic co-thickener. This innovative approach reduces the amount of clay used in the compound, sufficiently eliminating most of the negative characteristics associated with clay in joint compounds.
