Abstract: Acrylic polyols comprising hydroxy functional acrylic copolymers/resin involving an acrylic backbone having modified castor oil sourced hydroxyl functionalities and synthesized by co-reacting modified hydroxy functional Castor Oil with variety of acrylic monomers, styrene or its derivatives and optionally hydroxyalkyl acrylates/methacrylates and ethylenic monomer through solution polymerization in presence of an initiator. The hydroxyl functionality is solely or partially imparted through renewable Castor Oil wherein the resins were synthesized at upto 100% solids and at hydroxyl values ranging from 25-150 (mg KOH/gm). The synthesized resins when cured with suitable polyisocyanates or amino resin cross-linkers provided tough, glossy and chemical & weather resistant coatings.

Abstract: A synergistic emulsion polymer formulation adapted for facilitating achieving desired open time or wet edge time of any aqueous coating/paint composition on application to thus result in improved workability of the coating/paint composition. The synergistic emulsion polymer formulation and the coating/paint composition including the same comprises a latex polymer derived from copolymerization of mono-ethylenically unsaturated monomers. This in combination with select sorbitol ethoxylates esterified with fatty acids as an ingredient in the formulation/composition favors the slowing down of water evaporation from the composition considerably so that it remains amenable to touch up even after several minutes of application.

Abstract translation: 一种协同的乳液聚合物制剂，其适于在施用时促进任何水性涂料/涂料组合物的期望的开放时间或湿边缘时间，从而导致涂料/涂料组合物的改进的可加工性。 协同乳液聚合物配方和包含它们的涂料/涂料组合物包含衍生自单烯属不饱和单体的共聚合的胶乳聚合物。 这与与作为配方/组合物中的成分的脂肪酸酯化的选择性山梨糖醇乙氧基化物组合有利于显着地减少组合物中水的蒸发，使得即使在几分钟的施用后仍然可以接触。

Abstract: A formulation and process of preparing a functionalized-urethane alkyd resin, and a siliconized-urethane alkyd resin, is obtained from an alkyd based on semi drying/drying oils, or their fatty acids, having high iodine number of 120-170 (gm I2/100 gm), followed by grafting of epoxy-alkyl-alkoxy silane or silanol-functional silicone resin into an alkyd backbone. There is also subsequent urethanization of the organosilane grafted alkyd. Siliconized-urethane alkyd thus obtained were incorporated in solvent-borne pigmented-coating compositions and found suitable for preparing air drying 1 pack coatings providing excellent corrosion resistance, weathering and mechanical properties when applied on variety of substrates such as mild steel, corroded mild steel, other metals, alloys, glass, wood and cementitious materials
