Systems and methods relate to applying a coating to a substrate. Coatings can be generated using layer-by-layer application techniques. Typically, application of a first aqueous solution is alternated with application of a second aqueous solution. Example first aqueous solutions include polyethyleneimine (PEI) and hydroxy-terminated poly(dimethylsiloxane) (PDMS-OH). Example second aqueous solutions include silicate and PDMS-OH. In some instances, first aqueous solutions and/or second aqueous solutions additionally include methyl-terminated PDMS (PDMS-CH.sub.3).

The present invention relates to an alkali metal silicate coating formed from alkali metal silicate represented by the chemical formula M.sub.2O.nSiO.sub.2 and lithium silicate represented by the chemical formula Li.sub.2O.mSiO.sub.2, wherein M is selected from sodium, potassium, or a mixture thereof, n is from 2.9 to 3.7, m is from 4.2 to 4.8, and the molar ratio of M.sub.2O.nSiO.sub.2 to Li.sub.2O.mSiO.sub.2 is from 2.2 to 4.8; wherein the alkali metal silicate coating has a thickness of from 630 to 1,450 mg/m.sup.2, preferably from 700 to 1,400 mg/m.sup.2, in terms of SiO.sub.2 as measured by fluorescent X-ray spectrometry. The present invention further relates to a preparation method of the coating. The coating of the present invention has excellent heat resistance, hot water resistance and stain resistance, as well as excellent damage resistance.

A sprayable water blown low density polyurethane foam-forming formulation including: (A) an isocyanate component; (B) a polyol component, wherein the polyol component includes a surfactant composition; wherein the surfactant composition includes at least one phenol-free secondary alkyl alcohol ethoxylate, and wherein the at least one phenol-free secondary alkyl alcohol ethoxylate is at least one linear alkyl chain phenol-free secondary alcohol ethoxylate; and (C) water; a process for making the above sprayable water blown low density polyurethane foam-forming formulation; and a polyurethane foam made from the above sprayable water blown low density polyurethane foam-forming formulation.

Aspects of the disclosure are directed to a water-based aerosol composition, as well as related methods and resulting films. As may be implemented in accordance with one or more embodiments, a water-based aerosol composition includes a solvent including water, a liquid propellant, and a waterborne alkyd polymer material. The solvent, propellant and waterborne alkyd polymer operate together to propel the water-based aerosol composition onto a surface and cure the alkyd polymer on the surface, therein providing a coating on the surface that inhibits oxidation thereof.

The present invention relates to an anti-tack formulation of high solids content that uses effective amounts of a fine particle size talc, a water soluble cationic polymer, one or more nonionic surfactants, and one or more alkali metal fatty acid soaps. The high solids content anti-tack formulation is capable of being easily shipped to a customer's location and is stable and easily pumped after shipment to a customer. The high solids content anti-tack formulation generates a micro-flocculated pigment dispersion that can be subsequently diluted to a low solids content formulation for use in anti-tack applications, particularly rubber slab dipping applications. The anti-tack formulation provides improved anti-tack performance when coating uncured rubber products.
