The information presented here was acquired by UL from the producer of the product or material or original information provider. Byl process of claim 28wherein the water is present in the water-based composition in an amount of from 20 to 60 percent bgk weight based on the total weight of the composition.
It should be appreciated that the greater the amount of resin, the better the corrosion resistance. In this example, resin and molybdenum disulfide amounts were modified.
In this example, a formulation using tap water was compared to a formulation using deionized water. This example shows bykk where glycol ether co-solvents were and were not used. The film provided corrosion resistance but this particular formulation did not meet the performance requirements of MIL-L The formulation was stable and formed a homogenous film when spray applied.

However, UL assumes no responsibility or liability for the accuracy of the information contained on this website and strongly encourages that upon final product or material selection information is validated with the manufacturer. The panels were put in a salt fog chamber. In general, the molybdenum disulfide used in the practice of this invention has an average particle size in the range from 0.
However, much research has been conducted to replace dry film lubricants that are applied with potentially hazardous solvents, including lead-containing lubricants. Owing to its basicity and low cost, ammonia is the preferred nitrogen-containing basic compound.
By contrast, formulation 22B provided excellent corrosion resistance with no corrosion observed on the test panel.

In the table, all amounts are in grams, unless otherwise stated. The fastener of claim 41wherein the water-based composition further comprises a surfactant. In general, the amount of binder used is in the range of from about 5 to about 50 percent by weight of the composition.
The resulting formulation had a pH of 8.
In general the coating thickness is from about 1 micron to about 1 centimeter in depth. Agglomerations were not visible and did not byl when the product was drawn down or sprayed onto a metal flat panel. The composition is in the form of a dispersion when used. The composition may optionally include other friction reducing compounds.
Formulation 9B sprayed well with intermittent clogging.
This invention includes a composition that is water-based, has a low VOC content, and provides both lubricating and anticorrosive properties to metal surfaces on which the composition is 0228. Composition based on polytetrafluoroethylene suited for obtaining a self-lubricating layer on porous bronze bearings. The composition of claim 1wherein the polytetrafluoroethylene is present in an amount of from 0.
The process of claim 15wherein the polymeric binder is combined prior to the molybdenum disulfide. A nitrogen-containing basic compound is employed to adjust the pH of the system if needed. Typically, the temperature is the ambient temperature assuming the temperature is above the freezing point of water.
The other formulations showed no signs of delamination. Room temperature fast-drying highly-anticorrosive two-component waterborne epoxy coating and preparation method thereof.

It has been found that if the pH is unduly low, the formulation will be unstable or will not form a dispersion in the first instance. Bk 20C provided superior results to the other formulations. The composition is useful as a dry film lubricant for antigalling, antifretting, antisiezing, and ybk aid applications on a variety of surfaces such as those made of, for example, steel, aluminum, titanium, and so forth.
Epoxy-modified water-based alkyd resin and water-based alkyd amino stoving varnish and preparation method of epoxy-modified water-based alkyd resin and water-based alkyd amino stoving varnish. The composition of this invention may optionally 02 one or more dispersing agents, which may be referred to as wetting agents. Anti-corrosive paint of epoxy resin based on aqueous bitumen, and preparation method. This formulation passed the MIL-L protocol. In one embodiment, the surface to be treated is a metal fastener such as a metal bolt, stud, screw, and nut.
In general, the preferred coalescing agents are the propylene glycol ethers. In general the amount is about 0. High fluorocarbon content coating composition, method of application, and coated article. This application claims priority to provisional patent application Ser. 02
This invention has a number of advantages.
