TP films were inserted between the CFs layers pre-impregnated with DGEBA resin and DDS hardener.
The molar ratio of DGEBA to diamine was either 1:16, 1:8, or 1:2.5.
%, based on the amount of DGEBA) were added to the coating formulation.
(22-25) In the present study, DGEBA and polyaminoamide adduct (R41) coating system is modified with the direct incorporation of different types of inorganic NPs.
DGEBA, pentaerythritol tetrakis mercaptopropionate (PTKMP), iodobenzene diacetate (IBDA), tributylphosphine (TBP), and dimethoxyphenyl acetophenone (DMPA) were purchased from Aldrich Mexico.
The most widely explored epoxy resin is the diglycidyl ether of bisphenol-A (DGEBA) due to its low cost and crosslinking properties.
By using the FTIR-spectroscopy, the reaction between DGEBA and amine curing agent (4, 4'-methylenebis(3-chloro-2, 6-diethylaniline) was shown to proceed at higher temperatures (140-180[degrees]C).
Note that several of BPA's close chemical relatives, including bisphenol A diglycidyl ether (usually abbreviated as BADGE but sometimes seen as DGEBA), bisphenol F, bisphenol F diglycidyl ether (abbreviated as BFDGE), and bisphenol sulfonate (bisphenol S), are also used for lining food and beverage cans; these other products are more frequently used on aluminum cans.
(DGEBA)/ 4,4'-diaminodiphenyl methane (DDM) blends.
Comparative DSC kinetics of the reaction of DGEBA with aromatic diamines.
The present paper describes the in-situ cure monitoring of a particular epoxy based resin: DGEBA Diglycidyl Ether of Bisphenol A.
