Epoxy resins can be categorized into three distinct types based on the chemical structure of their resin backbone: aliphatic, cycloaliphatic, and aromatic epoxy resins. [4] An increase in the molecular length between reactive epoxy groups results in a reduction of crosslink density and resin modulus, while simultaneously enhancing the failure ...
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [1] The IUPAC name for an epoxide group is an oxirane.
It is primarily used as a curing agent or hardener in epoxy chemistry. This can be on its own or reacted with tall oil fatty acid (TOFA) and its dimer to make an amidoamine. [2] This amidoamine is then used as the curing agent for epoxy resin systems. TEPA is a pentadentate ligand in coordination chemistry.
Dimethylaminoethanol is used as a curing agent for polyurethanes and epoxy resins. It is a precursor to other chemicals, such as the nitrogen mustard 2-dimethylaminoethyl chloride. [ 3 ] The acrylate ester, dimethylaminoethyl acrylate is used as a flocculating agent.
A generic epoxide. In organic chemistry, an epoxide is a cyclic ether, where the ether forms a three-atom ring: two atoms of carbon and one atom of oxygen.This triangular structure has substantial ring strain, making epoxides highly reactive, more so than other ethers.
As a reagent in organic chemistry, DBU is used as a ligand and base. As a base, protonation occurs at the imine nitrogen. [5] Lewis acids also attach to the same nitrogen. [6] These properties recommend DBU for use as a catalyst, for example as a curing agent for epoxy resins and polyurethane.
BPA Free Plastic. BPS is used in curing fast-drying epoxy glues and as a corrosion inhibitor.It is also commonly used as a reactant in polymer reactions.. BPS has become increasingly common as a building block in polyethersulfone and some epoxies, following the public awareness that BPA has estrogen-mimicking properties, and widespread-belief that enough of it remains in the products to be ...
PETA is part of a family of acrylates used in epoxy resin chemistry and ultraviolet cure of coatings. Similar monomers used are 1,6-hexanediol diacrylate and trimethylol propane triacrylate . It is a derivative of pentaerythritol [ 2 ] One of the key uses of the material is in polymeric synthesis where it can form micelles and block copolymers.
