Patent number: 9212089Abstract: The present invention relates to a process for applying an optical coating to a substrate comprising the steps of (a) preparing an optical coating formulation comprising a solvent component and a film forming component; (b) using a die coater to form a coated substrate by applying the optical coating to a substrate, where the applied optical coating forms a wet film thereon having a thickness from 8 ?m to 100 ?m; (c) drying the coated substrate, where the coated substrate is in a substantially horizontal plane thereby converting the wet film to a dry film having a thickness of less than 1 ?m. The optical coating formulation comprises greater than 0.3 wt % to no more than 10 wt % solids relative to the total weight of the optical coating formulation. The coated substrate may be optionally cured.Type: GrantFiled: March 8, 2010Date of Patent: December 15, 2015Assignee: DSM IP ASSETS B.V.Inventors: Nanning Joerg Arsten, Pascal Josef Paul Buskens, Marnix Rooijmans

Patent number: 9096442Abstract: Complex inorganic titanate pigments with low dopant levels (i.e., less than about 5%) exhibit coloristic and enhanced infrared (IR) reflectance characteristics that make them useful in formulating colors exhibiting high IR reflectivity. This characteristic is becoming increasingly useful as a way to keep exterior surfaces and articles cooler during exposure to direct sunlight. Achieving this can decrease energy (e.g., cooling/air conditioning) consumption and costs. Low-loaded titanates can boost IR reflectivity by 1 to 10% in selected visual color spaces. Paint compositions containing those low loaded titanate pigments and a method for providing a surface with high infrared reflectance utilizing those pigments are also disclosed.Type: GrantFiled: July 3, 2012Date of Patent: August 4, 2015Assignee: The Shepherd Color CompanyInventors: James White, Doris Montgomery
