Patent number: 6055786Abstract: A roofing membrane heat seal indicator provides a positive, visually perceptible indication that a joint or seam has been raised to a sufficiently high temperature to achieve a proper seal. The heat seal indicator is applied adjacent and parallel to an edge of a roofing membrane which will be arranged on a roof to form the upper (exposed) surface of an overlapping membrane seam. As the adjacent surfaces of the overlapped membranes are heated, heat passes through the membrane to the heat seal indicator. The heat seal indicator may be a temperature sensitive ink pigmented with material that changes color upon being subjected to a temperature indicating that the membrane surface has been subjected to a sufficiently high temperature to achieve an appropriate seal. Alternatively, the indicator may be an adhered layer of a ground or flaked polymer, such as polyethylene, which is initially opaque but melts to become translucent, thereby indicating obtainment of a proper sealing temperature.Type: GrantFiled: May 30, 1996Date of Patent: May 2, 2000Assignee: OMNOVA Solutions Inc.Inventors: Michael J. Hubbard, Jeannemarie DeTorre, Keith Watt, Raymond J. Weinert

Patent number: 5770303Abstract: A latex binder composition comprises occluded composite particles containing at least a vinyl ester homopolymer or a copolymer thereof polymerized from acrylate and/or ethylene monomers, and a polymer polymerized from conjugated diene and/or vinyl substituted aromatic monomers and desirably unsaturated carboxylic acid monomers. The occluded composite particles are produced in the absence of crosslinking agents by first polymerizing the vinyl esters and optional acrylate and/or ethylene monomers, and subsequently in situ polymerizing the conjugated diene and/or vinyl substituted aromatic, etc., monomers in the presence of the vinyl ester latex particles. The occluded composite-particle latex contains phase separated domains which are neither a core-shell nor an inverted core-shell particle and provide properties which are superior to physical blends of the two classes of polymers when utilized as binders in paper coating formulations.Type: GrantFiled: January 5, 1996Date of Patent: June 23, 1998Assignee: GenCorp Inc.Inventors: Raymond J. Weinert, Satish C. Sharma, John P. Kovalchin, David M. Lee, Nick G. Triantafillopoulos, Ira John Westerman

Patent number: 5721309Abstract: A water based coating composition provides a stain resistant layer which adheres well to a substrate and is resistant to chemical attack by common household cleaning solvents such as isopropyl alcohol. The coating composition has a very low volatile organic compound content, thus providing an environmentally desirable alternative to organic solvent based coatings. The low volatile organic compound content of the composition substantially or completely eliminates the problems and expenses associated with solvent recovery for meeting chemical emission standards, and the potential for human exposure to solvent vapor is substantially eliminated or significantly reduced. The coating composition is aqueous based and incorporates a crosslinkable acrylic polymer latex, an amino resin crosslinking agent and a crosslinking catalyst. The polymer, crosslinking agent and catalyst are dispersed and/or solubilized in an aqueous medium.Type: GrantFiled: September 19, 1996Date of Patent: February 24, 1998Assignee: GenCorp Inc.Inventors: Satish C.
