For many applications, spray application is preferred. After application, depending on the circumstances, it may be desirable to allow up to a full day to dry to allow the coating to fully cure.
The process of claim 28wherein the water is present in the water-based composition in an amount of from 20 to 60 percent by weight based on the total weight of the composition. Representative examples of such wetting agents include but are not limited to sodium bis tridecyl sulfosuccinate, di 2-ethyl hexyl sodium sulfosuccinate, sodium bky, sodium dicyclohexyl sulfosuccinate, diamyl sodium sulfosuccinate, sodium iso-butyl sulfosuccinate, disodium iso-decyl sulfosuccinate, disodium ethoxylated alcohol half ester of sulfosuccinic acid disodium alkyl amido polyethoxy sulfosuccinate, tetra-sodium N- 1,2-dicarboxyethyl -N-octadecyl sulfosuccinamate, disodium N-octasulfosuccinamate, sulfated ethoxylated nonylphenol, 2-aminomethylpropanol, the condensation product of formaldehyde with naphthalene sulphonate, an alkylarylsulphonate, a lignin sulphonate, a fatty alkyl sulphate, ethoxylated btk, and an ethoxylated fatty alcohol.
082 surfactant lowers the surface tension of the coating as applied so that the surface is coated evenly. Fluorine-containing coating composition, primer for ETFE-based coatings, and coated article.
This product is the standard defoamer for water-based systems and the basis starting selection for the testing of a defoamer series. Then too, after being applied to a metal surface, the volatile components evaporate readily and such that the binder forms a consistent coating.
The process of claim 28wherein the molybdenum disulfide is combined prior to the polymeric binder.

Formulation 5C flowed and leveled properly over a freshly sand-blasted steel panel. In this example, resin and bym disulfide amounts were modified. In this example, a formulation using tap water was compared to a formulation using deionized water. This invention pertains to a water-based dry film lubricant composition that has a low volatile organic content VOC.
By contrast, increasing the amount of molybdenum disulfide leads to a longer wear life. In one embodiment, the amount is about 0.
Defoamer, VOC-free for aqueous systems: BYK
This formulation passed the MIL-L protocol. The process of claim 15wherein the water is present 0028 an amount of from 20 to 60 percent by weight based on the total weight of the composition.
The following table shows the formulations prepared. Room temperature fast-drying highly-anticorrosive two-component waterborne epoxy coating and preparation method thereof. Three aliphatic urethane dispersion resins were tested in place of the material used in Example 6, Formulation 6A. DPnB was then added with stirring. If used, the antifoam agent is typically present in an amount bk from 0. No blisters were observed for the duration of the test. Formulation 6A was too viscous for spraying, so water was added in nine 5 gram increments to reduce viscosity to a sprayable composition.
In one embodiment, the surface to be treated is a metal fastener such as a metal bolt, stud, screw, and nut. The amounts are in grams. Are you a distributor who is interested in being listed here?
In an effort to improve the stability of the molybdenum disulfide, the order of addition of the components was tested in this example. In one embodiment, the amount of fluorinated polymer employed is about 5 percent. In another broad respect, this invention is a metal fastener coated with the residue formed by evaporation of volatile components of a water-based composition comprising water, an acrylic or urethane resin, molybdenum disulfide, and polytetrafluoroethylene.
The process of claim 15wherein the molybdenum disulfide is combined prior to the polymeric binder. The coalescing agents used in this invention include a variety of glycol based compounds, including the ethylene and propylene derived glycol ether types.
In one embodiment, the amount of molybdenum disulfide is about 21 percent by weight. Non-limiting examples of representative surfactants which may optionally be used in the practice of this invention include non-ionic, anionic, cationic and amphoteric surfactants, such as monocarboxyl cocoimidoazoline, higher alkyl sulfate sodium salts, tridecyloxy poly alkyleneoxy ethanolethoxylated or propoxylated alkyl phenol, alkyl sulfonamides, C alkaryl sulfonates such as alkylbenzene sulfonates, cocoamphaodipropionate, cetylpalmitic alkanol amides, hydrogenated castor oil, isooctylphenyl polyethoxy ethanol, sorbitan monopalmitate, C alkyl pyrrolidone, cocoaminopropionic acid and polyethoxy amino salts thereof.
The composition is useful as a dry film lubricant for antigalling, antifretting, antisiezing, and assembly aid applications on a variety of surfaces such as those made of, for example, steel, aluminum, titanium, and so forth.

All amounts are in grams. It should be appreciated that the molybdenum disulfide may settle out if allowed to stand undisturbed.
A surfactant can be optionally employed in the practice of this invention. The process of claim 28wherein the binder is an aliphatic polyurethane resin.
