    摘要: Presently described are energy-curable resins, compositions, thermosets, coatings, and methods thereof. The curable resins described herein are (meth)acrylated resins derived from distilled tall oil rosin acids, distilled tall oil fatty acids, or a combination thereof. The curable resins can also include derivatives from rosin acids and/or fatty acids, such as cycloaddition products. The curable compositions undergo fast curing using UV and/or EB and provide enhanced performance of coatings, films, and printing inks, especially adhesion, stability and flexibility.

    摘要: A low gravity solid tolerant emulsifier and methods of making the same. The emulsifier includes a maleated amido-amine reaction product produced by: (1) reacting a fatty acid material comprising, and an amine material (e.g., a amine having a amine value of about 700 to about 1300 mg/g, such as AMINE HST) to produce an amido-amine reaction product; and (2) reacting the amido-amine reaction product with maleic anhydride to produce the maleated amido-amine reaction product. An invert emulsion fluids and drilling fluids that include the emulsifier of described herein and methods of using the same.

    摘要: An evaporative emission control canister system comprises an initial adsorbent volume having an effective incremental adsorption capacity at 25° C. of greater than 35 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane, and at least one subsequent adsorbent volume having an effective incremental adsorption capacity at 25° C. of less than 35 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane, an effective butane working capacity (BWC) of less than 3 g/dL, and a g-total BWC of between 2 grams and 6 grams. The evaporative emission control canister system has a two-day diurnal breathing loss (DBL) emissions of no more than 20 mg at no more than 210 liters of purge applied after the 40 g/hr butane loading step.
