Abstract:
There is now provided a sealant and elastomer made with a polyol having an unsaturation level of 0.04 to 0.07, manufactured with a basic salt of an alkaline earth metal or a basic salt of cesium, such as cesium hydroxide. The elastomers and sealants made therefrom exhibit an increasing modulus of elasticity when strained from 100 percent elongation to 300 percent elongation. The reduced unsaturation polyols are simple and inexpensive to make while imparting good physical properties to the sealants and elastomers.
Abstract:
Provided herein is a method for providing for an increase in germination rate of seeds by administering a plant growth regulator to the seeds as a seed dressing. Specifically provided is a method of promoting seed germination comprising administering to a seed a plant growth regulator comprising a substituted oxime-ether of formula (I) or (II) where R1 and R2 independently of one another are C1-C6-alkyl, n is 2 or 3 and R3 is hydrogen or C1-C6-alkyl wherein said plant growth regulator is applied at a low temperature.
Abstract:
A coating composition is described comprising a polymer resin binder and optically variable thin film pigment flakes. The pigment flakes have a multilayer thin film interference structure comprising a metal reflector layer having first and second parallel planar surfaces and, disposed on at least one of said first and second planar surfaces, at least one transparent dielectric layer. The pigment flakes further have an average particle size of 5 to 40 mu m and a particle size distribution where no more than 10 % of the particles have a particle size of greater than 50 mu m and substantially none of the particles have a particle size of greater than 125 mu m. This coating composition can be used to prepare a variety of coatings, especially color-plus-clear composite coatings such as those used in the automotive industry.
Abstract:
The present invention provides hygroscopic plant growth regulator formulations in solid forms and associated methods of making the powders and tablets. The most preferred formulation uses an effective amount of an N,N-dimethyl-piperidinium and/or N,N-dimethylammonium salt.
Abstract:
A polyurethane resin polymer is described. The polymer is terminated on each end with a silane group, and has appended thereto at least one additional silane group. The polymer is useful in a one-component polyurethane-based sealant composition.
Abstract:
The invention relates to energy absorbing, water blown, rigid polyurethane foams. The foams of the present invention are low density, predominantly open celled foams which exhibit a relatively constant consistency of compressive strength over deflection. Such foams are suitable as light weight alternatives in traditional energy absorbing applications.
Abstract:
Rapid production of honeycomb sandwich structures containing fiber-reinforced or non-reinforced thermoplastic honeycomb (1) adhered to skins or facing sheets (2) is accomplished by fusion bonding the skins or facing sheets (2) to the core (1) by means of thermoplastic film(s) (3) heated to the melt temperature (4) and applying sufficient pressure (5) fusion bond the skins or facing sheets to the core, followed, when necessary, by cooling the assembly (6) to prevent overheating of the core and/or skins or facing sheets.
Abstract:
Fiber-reinforced thermoplastic honeycomb (2) is prepared in a continuous manner one half cell at a time with the aid of formers (1, 4) by laying down a corrugated web of thermoplastic, selectively fusing the node-antinode demes, retracting the lowermost set of formers (1, 4), raising the formers by an amount at least equal to the thickness of the fused node-antinode surface, and repeating the process until a honeycomb of the desired depth is prepared. During at least a portion of the continuous manufacture, a thermoplastic web is utilized which has different characteristics from the webs utilized in the remaining portion of the process or the steps of laying down a corrugated web and fusing the demes are repeated without retracting and raising the lowermost set of formers so that a honeycomb material having areas or volumes possessing different physical properties than the remainder of the honeycomb is produced.
Abstract:
Provided herein is a composition comprising a plant growth regulator, octylpyrrolidone, and an emulsifier. The composition may be provided with a plant growth regulator comprising a substituted oxime-ether of formula (I) or (II), where R1 and R2 independently of one another are C1-C6-alkyl, n is 2 or 3 and R3 is hydrogen or C1-C6-alkyl. The compositions provided may also contain a blend of nonyl phenol ethoxylate and dioctyl sulfosuccinate. Also provided are methods of making the above compositions.
Abstract:
Food compositions and methods are provided for non-fat and low-fat food compositions containing a polyvinylpyrrolidone. The food compositions contain polyvinylpyrrolidone and other ingredients such as food stabilizers. Preferred compositions are non-fried foods, which include dairy products, baked goods, salad dressings, and meat products. Specific food compositions include ice cream, muffins and pourable salads.
