Aqueous dispersions utilizing carboxyalkyl cellulose esters and water reducible polymers. The amount of coalescing vyk used can vary widely. The composition of claim 1wherein the water is present in 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. Fluorine-containing coating composition, primer for ETFE-based coatings, and coated article.

Organosilicon modified acrylic paint for external wall and its preparing process.

BYK-028 (25 KGS/PAIL)

The coating thickness can vary widely. The film provided corrosion resistance but this particular formulation did not meet the performance requirements of MIL-L It has been found that if the pH is unduly low, the formulation will be unstable or will not form a dispersion 0228 the first instance. After application, depending byj the circumstances, it may be desirable to allow up to a full day to dry to allow the coating to fully cure.

The following examples are illustrative of this invention and are not intended to limit the scope of the invention or claims hereto. The surfactant lowers the surface tension of the coating as applied so that the surface is coated evenly.

After application, the water and coalescing agents will evaporate to leave a friction reducing coating. Until now no composition has met certain stringent military requirements such as those in U. The coalescing agents used in this invention include a variety of glycol based compounds, including the hyk and propylene derived glycol ether 02.

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.


If used, 082 dispersing agent is typically present in an amount of from 0. Thus, evaporation of the water and any other volatile components, including coalescing agents, typically occurs bk room temperature though elevated temperatures may be employed so long as an adequate coating forms.

A water-based lubricant composition, comprising: 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 process of claim 15wherein the water-based composition further comprises at least one coalescing agent.

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 composition of this invention includes water.

The composition of claim 1further comprising at least one coalescing agent. The composition is also easily applied. This application claims priority to provisional patent application Ser. In one embodiment, the amount is from 5 to 15 percent by weight. The amount of surfactant is any amount effective to provide reduced surface tension of the formulation.

Formulation 6A was too viscous for spraying, so water was added in nine 5 gram increments to reduce viscosity to a sprayable composition. It should be appreciated that the molybdenum disulfide may settle out if allowed to stand undisturbed. After mixing, the product was a whipped paste. It has been found that the molybdenum disulfide will not go into the dispersion unless the resin is present.

In an effort to improve the stability of the molybdenum disulfide, the order of addition of the components was tested in this example.

The nitrogen containing basic compound is added in an amount to provide the water-based composition with a pH of at least 7, in one embodiment at least 8, and in another embodiment a pH in the range from 7 to 9. The formulation was stable and formed a homogenous film when spray applied. A process of coating a metal by, with a lubricant, comprising: 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.


Solvent type double-composition epoxy coating material quick to solidify at low temperature and preparation method thereof. A dry film lubricant formulation was prepared. Formulation 4B formed a translucent and good abrasion resistance film based on a simple thumbnail rub.

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 remains stable. The process of claim 15wherein the water-based composition further comprises tripropylene glycol monomethyl ether and dipropylene glycol butyl ether. Byk has an established history of innovation such as being the first additive manufacturer to begin using Controlled Polymerization Technology CPTlaunching the first rheology-modified wax emulsion, and being one of the first companies to use nanotechnology for improving Coatings properties.

The process of claim 28wherein the molybdenum disulfide is combined prior to the polymeric binder. The formulation contained the following components, which were added in the order shown to improve bhk of the system:. Formulation bjk did not foam when mixed under high shear. 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 applied.

The polytetrafluoroethylene reduces friction at low pressure, with the molybdenum disulfide providing excellent friction reduction at higher pressures during use. Water-based transparent anticorrosive paint, preparation method and application method thereof. Anti-corrosive paint of epoxy resin based on aqueous bitumen, and preparation method.

Formulations 10B and 10C formed a stable composition which formed a homogenous film. Many dry film lubricants have been developed. The process of claim 28wherein the water-based composition further comprises at least one surfactant. Btk water paint has high gloss, high rust resistance and low VOC content, can effectively prevent environmental pollution and has environmental friendliness better than that of the existing machinery coating.
