A method for subsurface irrigation having the steps of; providing one or more hydrophobic porous uncoated tubes having a hydro head (HH), locating the tubes with at least a portion of their length within the rhizosphere of plants to be irrigated, and passing an aqueous irrigation liquid into the tubes during the growth phase of the plants to be irrigated at an applied pressure at or below HH. The tubes may be located in the proximity of seeds which become the plants to be irrigated following their germination. In this embodiment, aqueous irrigation fluid is passed into the tubes during a germination phase of the seeds at an applied pressure that is at least 10% higher than the applied pressure during the growth phase of the plants.

System and method for irrigation

A crosslinked coating composition formed from polyurethane polyols and blocked or unblocked polyisocyanates. The polyisocyanates, in particular, comprise at least bis(isocyanatomethyl)cyclohexane. The coating is substantially free from ester functionality that forms a contiguous part of the network backbone. A clearcoat formed from the described components and having a majority of urethane bonds is very resistant to environmental etch damage.

Etch resistant clearcoat

This invention relates to a method for forming a multi-layer coating on a vehicle body, comprised of applying primer coating, base coating, and clear coat layers in a wet-on-wet-on-wet manner, and simultaneously curing the applied three layers together in a single baking step. The primer layer comprises a film-forming binder comprising two acrylic polymers, the first being a caprolactone-modified branched acrylic polymer and the second being a caprolactone-modified linear acrylic polymer; and a crosslinking agent selected from aminoplast resin, blocked polyisocyanates, or mixtures thereof, wherein the composition is, essentially free of crosslinked nonaqueous dispersion resin particles or crosslinked microgel resin particles or both. The resulting multi-layered coating has excellent aesthetic appearance, strike-in resistance, chipping resistance, sag resistance, and film build even when formed in a three wet layered application method.

Method of forming multi-layer coating films on automobile bodies without a primer bake

The present process is directed to preparation of addition polymers in diluents that are subsequently reactive in coatings during cure, instead of in traditional hydrocarbon solvents. The polymers so prepared can be used as the main film-forming polymer in high solids coating compositions, especially those useful for finishing automobiles and truck exteriors.

Method of forming multi-layer coating on automobile bodies without a primer bake

This invention relates to a method for forming a multi-layer coating, comprising sequentially applying a layer of primer coating composition, a layer of base coat composition, and a layer of clear coat composition on an automotive substrate in a wet-on-wet-on-wet manner, and simultaneously curing the applied three layers together in a single baking step. The primer surfacer comprises a film forming binder, a volatile organic liquid carrier, and pigment(s); and the binder contains about (a) 40 to 95% by weight of a caprolactone-modified highly branched acrylic polymer having a hydroxyl and/or carboxyl monomer content, all or part of which has been reacted with caprolactone, of about 1 to 65% by weight and a weight average molecular weight of about 10,000 to 150,000; and (b) 5 to 60% by weight of an aminoplast resin crosslinking agent. The composition is essentially free of crosslinked nonaqueous dispersion resin particles or crosslinked microgel resin particles or both. The resulting cured multi-layered coating has excellent aesthetic appearance, strike-in resistance, chipping resistance, sag resistance, and film build even when formed in a three wet layered application method.

A process for producing building materials, such as asphalt, cement, concrete, mortar, or plaster board from liquid paint sludge containing water and paint solids produced from overspray in commercial paint booth operations. The preferred embodiment comprises adding the liquid paint sludge as the hydrating agent directly to the building material mix.

Process for producing building materials from raw paint sludge

The invention is directed to a process for making a reactive silane oligomer having low polydispersity, viscosity and volatility. The process utilizes reacting unsymmetrical difunctional silane monomers with water, diol monomers, or a combination thereof to make the reactive silane oligomer. The unsymmetrical difunctional silane monomers are with silane reactive groups having significantly different reactivities. Use of such reactive silane oligomers results in multi-component coating compositions having high miscibility, low VOC, low viscosity and high percentage of solids.

Process for producing reactive silane oligomers

A sprayable coating composition that contains at least one soluble film-forming silicon-containing compound having, on average, more than one fuctionalized silicon group, a volatile organic carrier, a polymer microparticle component, and a catalyst; a substrate coated with the composition; a process for coating the substrate to provide a protective finish; the finish-protected substrate; certain oligomeric compounds and a process therefor.
