A recently filed patent (Publication Number: US20230312911A1) describes an epoxy composition that includes an epoxy resin, a curing agent, and a bio-based epoxy compound. The bio-based epoxy compound has a specific structure, referred to as Structure I.

The patent claims that the bio-based epoxy compound can be a ß-isomer and consists of 100% bio-based carbon atoms according to ASTM D6866. It is present in the composition in a quantity ranging from 0.1 to 30% by weight based on the total weight of the composition.

The epoxy resin used in the composition can be selected from a wide range of options, including bisphenol A epoxy resins, bisphenol F epoxy resins, and epoxy resins derived from various sources such as cashew nut shell liquid oil, soybean oil, and sunflower. The epoxy resin is present in the composition in a quantity ranging from 1 to 75% by weight.

The curing agent used in the composition can be a latent curing agent, an amine, a thiol, an anhydride, Mannich base, phenolic nucleophiles, or a mixture thereof. If a latent curing agent is used, the epoxy composition is a one-component (1k) composition. If an amine, thiol, Mannich base, or a mixture thereof is used, the epoxy composition is a two-component (2k) composition with separate components for the curing agent and the epoxy resin. The curing agent is present in the composition in a quantity ranging from 20 to 60% by weight.

The composition may also include a toughener, which can be selected from various options such as core shell rubber particles, liquid rubbers, OH-terminated polyether polyols, and inorganic fillers. The toughener is present in the composition in a quantity ranging from 0.1 to 50% by weight.

The patent claims that the epoxy composition can be used as a structural adhesive, a coating, or a primer. Additionally, the patent claims a cured product of the epoxy composition.

In summary, the patent describes an epoxy composition that includes an epoxy resin, a curing agent, and a bio-based epoxy compound with a specific structure. The composition can be used for various applications and can be formulated as a one-component or two-component system. The patent also mentions the inclusion of a toughener in the composition.
