Bisphenol A diglycidyl ether (commonly abbreviated BADGE or DGEBA) is an organic compound and is a liquid epoxy resin. [1][2][3][4][5] The compound is a colorless viscous liquid (commercial samples can appear pale straw-coloured). [6][7] It is a key component of many epoxy resin formulations. Addition of further Bisphenol A and a catalyst and ...
Epoxy. A syringe of "5-minute" epoxy glue, containing separate compartments for the epoxy resin and the hardener. Structure of the epoxide group, a reactive functional group present in all epoxy resins. Epoxy is the family of basic components or cured end products of epoxy resins.
Properties. Chemical formula. C17H20O2. Molar mass. 256.345 g·mol −1. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. Tetramethyl bisphenol F (TMBPF) is a new coating intended as a safer replacement [1] for bisphenol A and bisphenol F to use in epoxy ...
Infobox references. 1,4-Butanediol diglycidyl ether (B14DODGE) is an organic chemical in the glycidyl ether family. It is aliphatic and a colorless liquid. It has two epoxide (oxirane) groups per molecule. [1] Its main use is in modifying epoxy resins especially viscosity reduction.
Infobox references. Bisphenol A (BPA) is a chemical compound primarily used in the manufacturing of various plastics. It is a colourless solid which is soluble in most common organic solvents, but has very poor solubility in water. [ 2 ][ 7 ] BPA is produced on an industrial scale by the condensation reaction of phenol and acetone.
The epoxy value is defined as the number of moles of epoxy group per 100g resin. So as an example using an epoxy resin with molar mass of 382 and that has 2 moles of epoxy groups per mole of resin, the EEW = 382/2 = 191, and the epoxy value is calculated as follows: 100/191 = 0.53 (i.e. the epoxy value of the resin is 0.53). [6]
Bisphenol S (BPS) is an organic compound with the formula (HOC6H4)2SO2. It has two phenol functional groups on either side of a sulfonyl group. It is commonly used in curing fast-drying epoxy resin adhesives. It is classified as a bisphenol, and a close molecular analog of bisphenol A (BPA).
FR-4. FR-4 (or FR4) is a NEMA grade designation for glass-reinforced epoxy laminate material. FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing). "FR" stands for "flame retardant", and does not denote that the material complies with the standard UL94V-0 unless ...
