Tautilar Of particular interest in many military applications are new dry lubricants that are water-based, and which provide both corrosion resistance and lubricating properties. However, films dried with compressed air did not show such pigment separation. For formulation 8B, liquid phase separation occurred quickly. The content of such third party sites is not within our control, bym we cannot and will not take responsibility for the information or content.

Waterborne polyurethane modified epoxy steel structure anti-corrosive paint and preparation method thereof. Formulation 4D formed a film similar in appearance to formulation 4C, with good abrasion resistance. In general the coating thickness is from about 1 micron to about 1 centimeter by depth.

EXAMPLE 8 In an effort to improve the stability of the molybdenum disulfide, the order of addition of the components was tested in this example. It should be appreciated that molybdenum disulfide as received may impart acidity to the composition, which may require addition of base so that the resin stable. The surface can be treated with multiple coatings of the formulation to build up the thickness of the coating. The composition of this invention may optionally include one or more dispersing agents, which may be referred to as wetting agents.

The formulations were stable and formed homogenous films upon spray application. The process of claim 15wherein the water-based composition further comprises at least one coalescing agent. While the formulation did not meet the performance requirements of MIL-L, the formulation did provide corrosion resistance. Advantageously, the composition can meet the current military requirements under U. Thus, ybk of the water and any other volatile components, including coalescing agents, typically occurs at room temperature though elevated temperatures may be employed so long as an adequate coating forms.

The other formulations showed no signs of delamination. Additional deionized water was added in 25 gram aliquots to reduce the viscosity to form a sprayable mixture. The composition is also easily applied.

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.

The composition includes from about 1 to about 90 percent by weight of water. Formulation 8A was somewhat whipped with air, but did not separate overnight at room temperature. The composition of claim 1wherein the binder is an aliphatic polyurethane resin. In another broad respect, this invention is a water-based lubricant composition, comprising: Formulation 4C formed a well dispersed film with no agglomerations, reduced surface tack, and had slightly less structural integrity than formulation 4B.

The formulation included deionized water, The coalescing agents can also serve to have secondary effects such as allowing flow and leveling to wet steel, lower surface tension, and provide defoaming properties. The polytetrafluoroethylene reduces friction at low ybk, with the molybdenum disulfide providing excellent friction reduction at higher pressures during use.

BYK is easy to incorporate. The process of claim 15wherein by molybdenum disulfide is present in an amount of from 0. The fastener of claim 41wherein the water-based composition further comprises at least one coalescing agent.

The following examples are illustrative of this invention and are not intended to limit the scope of the invention or claims hereto. The amount of coalescing agent used can vary widely.

The formulation of this invention can be applied to the surface to be treated in a variety of ways. Metalworking with an aqueous synthetic lubricant containing polyoxypropylene-polyoxyethylene-polyoxypropylene block copolymers. By, one embodiment, the amount of molybdenum disulfide is about 21 percent by weight. A method for preparing a construction machine according to a water paint according to any of claimscharacterized in that it comprises the following steps: The composition is in the form of a dispersion when used.

The formulation was stable and when sprayed formed a homogenous film. Formulations 10B and 10C formed a stable composition which formed a homogenous film. All formulations formed whipped products with some elevated viscosity.

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. The fastener of claim 41wherein the polytetrafluoroethylene is present in the water-based composition in an amount of from 0.

In one particular embodiment, the molybdenum disulfide has an average particle size of about 5 microns, containing particles in the range from 0.

USB1 — Low volatile organic content lubricant — Google Patents The polytetrafluoroethylene is provided as a fine powder, which provides lubricity at relatively low pressure, with the molybdenum disulfide providing excellent lubricity at higher pressures. The diluted formulation 6B was not spray applied. Room temperature fast-drying highly-anticorrosive two-component waterborne epoxy coating and preparation method thereof.

The fastener of claim 41wherein the water-based composition further comprises an antifoaming agent. The ammonia is present to reduce the acidity of the formulation. The process of claim 28wherein the water-based composition further comprises an antifoaming agent.

In this example, a formulation using tap water was compared to a formulation using deionized water. Related Articles.

The process of claim 15wherein the polymeric binder is combined prior to the molybdenum disulfide. Formulation 8A was somewhat whipped with air, but did not separate overnight at room temperature. In this example, a formulation using tap water was compared to a formulation using deionized water. The composition is in the form of a dispersion when used. The composition may optionally include btk friction reducing compounds. The process of claim 28wherein the water-based composition further comprises at least one coalescing agent.

The process of claim 28wherein the water-based composition further comprises an antifoaming agent. After mixing, the product was a whipped paste. Search Import Export Data of India The sprayed test panels were subjected to corrosion resistance testing according to MIL-L The formulation was spray applied to a phosphate treated steel panel and cured for 24 hours at 70 degrees Centigrade, and then tested according to MIL-L The coalescing agents used in this invention include a variety of glycol based compounds, including the ethylene and propylene derived glycol ether types. The fastener of claim 41wherein the water-based composition further comprises tripropylene glycol monomethyl ether and dipropylene glycol butyl ether. The following examples are illustrative of this invention and are not intended to limit the scope of the invention or claims hereto.

Gardalkree After dilution, the coating formed agglomerations upon spraying. In general the amount is about 0. Year of fee payment: The polytetrafluoroethylene reduces friction at low pressure, with the molybdenum disulfide providing excellent friction reduction at higher pressures during use. The composition of claim 1wherein the composition has a pH in the range from 8 to In another embodiment the composition contains water in an amount from about 25 to about 50 percent by weight. By contrast, increasing the amount of molybdenum disulfide leads to a longer wear life.
