The molecule has 2 oxirane functionalities, and so a key use is modifying and reducing the viscosity of epoxy resins. [9] [10] These reactive diluent modified epoxy resins may then be further formulated into CASE applications: coatings, [11] adhesives, sealants, and elastomers. It produces epoxy coatings with high impact resistance. [12]
A water-based primer, used primarily on wood. A primer (/ ˈ p r aɪ m ər /) or undercoat is a preparatory coating put on materials before painting.Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted.
SU-8 is a commonly used epoxy-based negative photoresist. Negative refers to a photoresist whereby the parts exposed to UV become cross-linked, while the remainder of the film remains soluble and can be washed away during development. As shown in the structural diagram, SU-8 derives its name from the presence of 8 epoxy groups.

BMW and Yamaha Motor have invested in U.S.-based rare earths processing startup Phoenix Tailings, the latest move by manufacturers to boost production of the strategic metals outside of China.
As cases of the HMPV virus continue to increase in the U.S. and in China, here's what you need to know about the virus.
Bisphenol A diglycidyl ether slowly hydrolyzes to 2,2-bis[4(2,3-dihydroxypropoxy)phenyl)propane (bis-HPPP). Similarly, DGEBA reacts with acrylic acid to give vinyl ester resins . The reaction results in opening of the epoxide ring, generating unsaturated esters at each terminus of the molecule.
