Patent number: 11879048Abstract: Sealants and caulks (i.e., polymeric fillers) disclosed herein are polymeric fillers that comprises a polymeric material composition and one or more lipolytic enzymes dispersed within the polymeric material composition. In preferred embodiments, the polymeric material composition is an acrylic latex sealant such as that in the form of a caulk and the one or more lipolytic enzymes comprises a lipase such as, preferably, a triacylglycerol lipase. Advantageously, the one or more lipolytic enzymes of such sealants and caulks degrades lipid-containing contaminants and resulting lipid-containing stains that contain lipids. The degradation is a result of the ability of a lipolytic enzyme to catalyze a reaction on a lipid-containing substance (i.e., a substrate) to hydrolyze or move (e.g., intra-esterification) ester bonds of such lipid-containing substance. This lipid-degradation functionality at least partially inhibits the growth of such mold and mildew resulting from exposure to lipid-containing contaminants.Type: GrantFiled: February 3, 2021Date of Patent: January 23, 2024Assignee: REACTIVE SURFACES LTD., LLPInventor: Claude Steven McDaniel
