  • Patent number: 11879048
    Abstract: 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.

  • Patent number: 11845863
    Abstract: Aqueous polyurethane dispersions and coatings and heat-activatable adhesives made from the dispersions are disclosed. The dispersions include a polyurethane reaction product of a polyester polyol and a polyisocyanate. The polyester polyol comprises recurring units of at least one C2-C6 aliphatic diol, at least one aliphatic or cycloaliphatic C4-C10 dicarboxylic acid, and an aromatic diacid source, which can be recycled PET. The dispersion is formulated using 1 to 3 moles of an acid-functional diol per mole of polyester polyol. Dispersions for the adhesives are produced at NCO/OH molar ratios within the range of 0.90 to 0.98. The adhesives successfully bond a wide range of plastic and metal materials, often demonstrating substrate failure, even with steel. This contrasts with commercial adhesives such as EVA that exhibit only adhesive failure with the same substrates.
