The present invention relates to a two-component putty comprising (1) a base component and (2) a curing component, wherein the base component comprises: a polycarbonate diol having a hydroxyl number in the range of from 50 to 500 mg KOH/g; a further resin component having a hydroxyl number of at least 300 mg KOH/g; and an inorganic filler, wherein the curing component comprises a polyisocyanate, and wherein the amount of the inorganic filler is in the range of from 35 wt % to 60 wt %, based on the total weight of the putty, the putty contains less than 5 wt % of organic solvent, and the viscosity of the putty is in the range of from 30,000 mPa.Math.s to 250,000 mPa.Math.s. The present invention also relates to a method for coating a substrate by applying such putty and allowing the applied putty to cure. The invention further relates to a coated substrate obtainable by such method and the use of such two-component putty for improving erosion resistance of a substrate.

Blends comprising an aromatic polyester polyol and a 1 to 10 wt. % of a fatty acid derivative are disclosed. The fatty acid derivative is a C.sub.8 to C.sub.18 fatty acid ester or a C.sub.8 to C.sub.18 fatty acid amide. Also disclosed are rigid PU or PU-PIR foams that comprise a reaction product of water, a catalyst, a foam-stabilizing surfactant, a polyisocyanate, a blowing agent, and the polyester polyol/fatty acid derivative blends. Surprisingly, low-temperature R-values of rigid foams based on pentane blowing agents can be improved significantly by using blends of aromatic polyester polyols and a minor proportion of readily available fatty acid derivatives. In some aspects, the difference between initial R-values of the foam measured at 75? F. and 40? F. is at least 5% greater than that of a similar foam prepared in the absence of the fatty acid derivative.

The waterborne amino baking varnish is prepared with raw materials in percent by weight comprising: 25-40% of a waterborne polyurethane, 4-5% of a waterborne epoxy resin, 7-10% of a waterborne amino resin, 25-35% of deionized water, 1.5-2.5% of a pH regulator, 0.3-0.5% of a wetting agent, 0.2-0.6% of a defoamer, 0.5-1% of a dispersant, 1-5% of a cosolvent, 10-20% of a pigment and a filler, 2-5% of nano-alumina, 0.3-0.5% of lithium magnesium silicate, 0.3-0.5% of a thickener, and 0.5-0.8% of a leveling agent.

A method of preparing a product derived from a rhamnolipid includes the steps of: providing a rhamnolipid, combining the rhamnolipid with a reagent, allowing the rhamnolipid and reagent to react to form a product derived from the rhamnolipid, and collecting the product derived from the rhamnolipid. An exemplary product is dimeric -hydroxy fatty acid.

The invention relates to a hyperbranched polymer comprising: a) a hyperbranched polycondensate with hydroxyl end groups, amino end groups, or a combination thereof condensed to b) one or more linking groups connected to c1) one or more polyethylene glycol monomethyl ethers and c2) one or more poly(C.sub.2-C.sub.3)alkylene glycol mono-(C.sub.8-C.sub.22)-alkyl ethers, wherein the weight ratio of components c1):c2) is from 9:1 to 1:9. It further relates to a process for producing the polymer, to a composition comprising the polymer and an active ingredient, and to a method for controlling phytopathogenic fungi or undesired vegetation or insect or acarid infestations or for regulating the growth of plants.

A two-component solventless adhesive composition is disclosed, the composition comprising an isocyanate component comprising an isocyanate prepolymer that is the reaction product of reactants comprising at least one polyisocyanate, at least one polyester polyol, at least one polyether polyol, and at least one polyol comprising a hydroxyl and COOH acid functionality. The adhesive composition further comprises a polyol component comprising at least one polyester polyol, at least one polyether polyol, or a combination thereof. A method for forming a laminate using the adhesive composition and a laminate itself are also disclosed. The method comprises forming a solventless adhesive composition, applying a layer of the adhesive composition to a surface of a film, bringing the layer into contact with a surface of another film to form a laminate, and curing the adhesive composition. A laminate made according to the method is further disclosed.

Star block copolymers having 3 to 8 arms are formed as a 3D foam scaffold having tailor-made pore sizes that mimic an actual cell size of a specific animal and/or human tissue and/or organs. The pore sizes are made within the elastomeric foams via a salt leaching process wherein a salt of a specific particle size is blended within the star block copolymers and crosslinked as by polyisocyanate compounds. Water or other suitable solvent are utilized to dissolve and leach out the salt leaving an open pore system. Animal and/or human cells are then injected into the 3D elastomeric foam scaffold that contains pendant liquid crystals on the star block copolymer whereby with the aid of nutrients, cells are formed within the pore system that are viable for at least three months. The size of the pore is predetermined to produce a desired cultured cell having a desired size. The tissue and/or cells within the elastomeric scaffold can be applied to animal and/or human tissue and/or organs whereupon they grow and reconstruct the damaged, injured, diseased, etc., area and result in a healthy, repaired, and viable tissue or organ. The elastomeric liquid crystal containing foam scaffold will degrade naturally and/or also be consumed by the growing cells so that it no longer exists. In other words, a specific type of animal or human cell can be culturally produced having a predetermined average cell diameter that is substantially or essentially the same diameter of a natural cell.

Provided herein is a conductive adhesive composition containing: a thermosetting resin having a functional group reactive with an epoxy group; an epoxy resin; a conductive filler; and urethane resin particles having a mean particle diameter of 4 m or more and 13 m or less and a hardness of 55 or more and 90 or less measured by a type A durometer in conformity with JIS K6253.

A rigid PU or PU-PIR foam comprising a reaction product of water, a catalyst, a foam-stabilizing surfactant, a polyisocyanate, a blowing agent and a blend comprising: (a) 90 to 99 wt. % of an aromatic polyester polyol having a hydroxyl number within the range of 150 to 400 mg KOH/g; and (b) 1 to 10 wt. % of a fatty acid derivative selected from the group consisting of C.sub.8 to C.sub.18 fatty acid esters and C.sub.8 to C.sub.18 fatty acid amides.

Polyester polyols are generally disclosed, including methods of making and using them. In some embodiments, the polyester polyols are incorporated into a block copolymer, such as a polyurethane block copolymer. In some embodiments, the polyurethane block copolymers can be used as compatibilizing agents, which can be used, for example, in polymer blends, polymer alloys, solutions, emulsions, as well as in extruded and injection molded articles. In some embodiments, at least a portion of the polyurethane block copolymer is derived from a renewable source.
