  • Patent number: 9718987
    Abstract: This invention relates to bio-based polyfunctional carboxylic acids reacted with vinyl ether compounds to form liquid vinyl-blocked bio-based polyfunctional carboxylic acids. These liquid vinyl-blocked bio-based polyfunctional carboxylic acids can be mixed with a polyfunctional vegetable oil-based epoxy resin to form a homogeneous curable coating composition. Upon curing at elevated temperature, thermoset coatings are formed which have excellent hardness, solvent resistance, adhesion, and flexibility. The invention also relates to the use of a curable coating composition comprising at least one polyfunctional vegetable oil-based epoxy resin and at least one vinyl-blocked bio-based polyfunctional carboxylic acid, which may be coated onto a substrate and cured thermally. Methods of making the vinyl-blocked bio-based polyfunctional carboxylic acids and curable coating compositions and substrates containing the same are also disclosed.

  • Patent number: 8609767
    Abstract: Toughened thermosetting resins comprising thermosetting resins and rubber particles having an average particle size in the range of 20 to 500nm. The toughened resins are obtained by mixing a fully vulcanized powdery rubber having an average particle size in the range of 20 to 500nm with thermosetting resin prepolymers and then curing them. The toughened thermosetting resins comprise rubber phases having a small, uniform and stable particle size, which results in a very significant toughening effect, especially when crazes rapidly grow (as in a standard Izod impact test). The toughened thermosetting resins are excellent in impact resistance, strength, modulus and heat resistance, and when appropriately toughened, the thermosetting resins can be enhanced in terms of impact strength, glass transition temperature and heat distortion temperature.

  • Patent number: 7932322
    Abstract: The invention relates to viscosifiers, especially terminated polymers that have functional terminal groups, said polymers being pre-extended by polyamines, polymercaptans, (poly)aminoalcohols, (poly)mercaptoalcohols or (poly)aminomercaptans and being reacted to give polymers that are terminated by other functional groups. The viscosifiers have a low content in educts or educt descendants that deteriorate the properties of compositions. They are also charaterized in that the formation of high-molecular addition products is considerably reduced or even excluded so that products obtained have low viscosity and good storage stability. The epoxy-terminated polymer of formula (I) is especially preferred.

  • Publication number: 20110049426
    Abstract: Use of a resin system for making a composite material in a liquid moulding process. The resin system comprises an epoxy component and at least one curing agent, and at least 35 wt. % of the epoxy component is one or more naphthalene based epoxy resin. There is also provided a cured composite material, and a method of making the cured composite material in a liquid moulding process which comprises placing fibre reinforcement and the resin system in a mould and curing. The resin system and the methods of making a cured composite material are particularly applicable to liquid moulding processed such as resin trans moulding (RTM), vacuum assisted resin transfer moulding (VARTM), Seeman composite resin infusion moulding (SCRIMP), resin infusion under flexible tooling (RIFT), and liquid resin infusion (LRI).
