A binder composition includes an epoxidized vegetable oil or a derivative thereof having an epoxy group content of 1 to 12 weight percent, based on the total weight of the epoxidized vegetable oil; a carboxyl-functionalized resin; and a liquid reactive diluent. A combined acid value of the carboxyl-functionalized resin and the liquid reactive diluent is 50 to 500. Uses of the binder composition, for example in composites, coatings, elastomer formulations, and adhesives are also disclosed.

Liquid binder compositions and uses thereof

In some aspects, the disclosure relates to processes involving a two-component resin system to provide a composite matrix binder. The first component may be a liquid reactive diluent, like an epoxidized vegetable oil, and the second component may be a solid, powdered polymer component, like a carboxylic functional acrylic or polyester, that may react with the liquid component. The liquid component may wet and coat the filler materials, while the powdered resin may soften/melt at higher temperatures below its threshold reactive temperature, thus allowing it to flow, diffuse and mix with the liquid component. This facilities processing and allows use of higher molecular weight resins and/or a higher Tg polymers without solvent use. When used in stone composite formulations with fillers like quartz and/or titanium dioxide, example resulting products have high hardness, very low water absorption, and high mechanical strength along with stain, chemical, and heat resistance.

Epoxidized oil binder compositions and process for preparation of thermoset hardened products

Aqueous compositions of carboxylic acids, carboxylate esters, and carboxylate salts are generally disclosed, including methods of using such compounds to make various polymers, including, but not limited to, polyesters, polyamides, and polycarbamates. In certain embodiments, the carboxylic acids, carboxylate esters, and carboxylate salts are derived from a renewable source, such as a natural oil.

Aqueous monomer compositions and methods of making and using the same

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.

Polyester polyols and methods of making and using the same

In some aspects, the disclosure relates to thermoset polymeric compositions consisting of functional bio-based epoxies and/or their derivatives (e.g. epoxidized vegetable oil(s)), along with carboxyl functional acrylics and/or polyesters. When cured, example compositions yield high performance products suitable for composite, coating, adhesive, sealant, and/or elastomer applications. When used in stone composite formulations with suitable fillers like quartz and titanium dioxide, example products have high hardness, very low water absorption, and high mechanical strength along with stain, chemical, and heat resistance. When used in coating formulations, example cured films have excellent adhesion, high gloss, clarity, toughness, low water absorption, solvent and chemical resistance, flexibility, and impact resistance without compromising hardness. Coating formulation properties may also include exterior durability. The composition properties may be selectively modified to hard, soft, tough, or elastomeric by selecting the appropriate stoichiometry and type of functional resin to react with epoxy(ies)/derivative(s).
