Patent
Sherwin Williams Corporation | Date: 2016-10-12

A fluid dispensing apparatus may be used to dispense a paint fluid from a paint container that is under pressure and that has a pierceable membrane. The fluid dispensing apparatus may include a valve body having a bore, an adaptor having a bore and a piercing member, and a nozzle having a bore. The fluid dispensing apparatus may be operable to pierce the pierceable membrane to communicate the paint within the paint container with the adaptor bore and with the valve body bore. The nozzle may be operable to permit the paint to flow under the pressure out of the paint container, through the adaptor bore, through the valve body bore and through the nozzle bore to ambient.

Provide is a tool that includes a handle assembly including a top and bottom portion and a blade disposed between the top and bottom portion having first and second ends and an opening at its first end. The opening includes first and second notches opposed to one another. The tool also includes a latch assembly disposed between the top and bottom portion that is movable between first and second positions, the latch assembly including a latch having a protrusion that engages one of the first or second notches in the first position and disengages from the one of the first or second notches in the second position. The blade is rotatable about the first end between a closed positioned where the first notch is engaged by the protrusion, and an open position where the second notch is engaged by the protrusion.

A method and kit for forming a seal around a roof penetration is disclosed. The method comprises dispensing a one-part moisture curable sealant into pitch pan formed around a roof penetration. The one-part moisture curable sealant contains a polymer having non-terminal silane groups. The incorporation of non-terminal silane groups can provide for a greater number of crosslinking points than terminal silane groups. The non-terminal silane groups can be placed at specific points along the polymer backbone and the number of crosslinking points, or concentration of crosslinking units, can be controlled. Generally, as the crosslinking points can be provided along the polymer chain, the number of crosslinking points is increased, especially as compared to polymers only having terminal silane groups. Increasing the number of crosslinking points can result in improved elasticity and cure-through as compared with silyl-terminated polymers, in addition to other advantages.

A water-based, two-part primer for metal substrates includes at least a first and second part, combined in a ratio of about 1:1. The first part of the primer may be substantially free of volatile organic compounds and include a colloidal silica present in the amount of about 20 weight percent to about 80 weight percent, based on the total weight of the first part; a silane coupling agent selected from the group consisting of epoxysilanes, mercaptosilanes, and modified silanes having a functional group active to an epoxy group, the silane coupling agent present in the amount of about 0.05 weight percent to about 15 weight percent based on the weight of the first part; and a cellulose ether in the amount of about 0.1 weight percent to about 2 weight percent. The second part may include from about 50% by weight zinc powder. The primer may be conventionally sprayable for use in large ship-building operations.

An unsaturated polyester resin composition comprising an unsaturated polyester, a reactive monofunctional (meth)acrylate monomer or oligomer; a reactive multifunctional (meth)acrylate monomer; wherein the resin composition is substantially free of styrene and acetoacetate functional monomers.


Patent
Sherwin Williams Corporation | Date: 2016-06-01

In one embodiment, a single component waterborne coating composition includes water; a branched polyester polyurethane dispersion; a polycarbonate polyurethane dispersion blend including a branched polycarbonate PUD and an unbranched, hydroxyl functional, polycarbonate polyurethane dispersion; and a fluorinated acrylic latex resin. In another embodiment, the fluorinated acrylic latex resin may be replaced with a hybrid resin selected from the group consisting of a fluorinated acrylic and polyester polyurethane dispersion hybrid resin and a fluorinated acrylic and polycarbonate polyurethane dispersion hybrid resin.
