Patent number: 6319548Abstract: A cohesive coating composition (16) having differential adhesion properties is applied to window glass (12) without regard to covering adjacent trim material (14) which is to be subsequently painted. The DAC (differential adhesion composition) coating (16) is characterized by high adhesion to wood, metal, plastics and painted surfaces and at the same time by selective adhesion to glass-like surfaces, so that the coating composition (16) may be easily scraped, peeled, or otherwise lifted from the glass (12), together with any paint overlay thereon, after the painting operation of the window frame (14) is completed. When subjected to sheer forces of pulling and scraping, the cohesive properties of DAC coating (16) when considered in combination with a relatively low adhesion to glass, allows the coating (16) to be removed in long continuous strips rather than fracturing into small pieces.Type: GrantFiled: June 7, 1995Date of Patent: November 20, 2001Assignee: The Trimex CompanyInventor: Walter VanWinckel

The composition may also comprise one or more fillers or heat absorbing materials. In one embodiment, the composition is used to fill the cavity between a preformed lens block and a lens. In another embodiment the composition is used to form a lens block. Methods of holding a lens blank are taught. Tapes that provide a receptive surface against which the composition may be adhered are disclosed.Type: GrantFiled: April 7, 1998Date of Patent: August 22, 2000Assignee: 3M Innovative Properties CompanyInventors: Sharon R. Benjamin, Michael Govek, John H. Ko, Joel D. Oxman, Carole Sedlock, F. Andrew Ubel, Todd R. Williams

Patent number: 6080394Abstract: One composition is a non-aqueous polar solvent-in-oil emulsion containing a non-aqueous polar solvent phase dispersed in a silicone oil continuous phase by an emulsifier. A second composition is a non-aqueous polar solvent-in-oil-in-water multiple emulsion of the type PS.sub.1 /O/w which contains a non-aqueous polar solvent phase PS.sub.1 dispersed in a silicone oil as a first continuous phase of a primary emulsion PS.sub.1 /O by an emulsifier. The primary emulsion PS.sub.1 /O is dispersed in a second continuous aqueous phase W to form multiple emulsion PS.sub.1 /O/W. A third composition is a non-aqueous polar solvent-in-oil-in-non-aqueous polar solvent multiple emulsion of the type PS.sub.1 /O/PS.sub.2 which contains a non-aqueous polar solvent phase PS.sub.1 dispersed in a silicone oil as a first continuous phase of a primary emulsion PS.sub.1 /O by an emulsifier. The primary emulsion PS.sub.1 /O is dispersed in a second continuous non-aqueous polar solvent phase PS.sub.2 to form multiple emulsion PS.sub.Type: GrantFiled: November 8, 1999Date of Patent: June 27, 2000Assignee: Dow Corning CorporationInventors: Zuchen Lin, William James Schulz, Jr., Janet Mary Smith
