Comparing FTIR spectra of the epoxy resin before (curve a) and after (curves b and c) cured by the hardener
Based on the zeta potential study, we choose those hardeners
that form stable mixtures with AEH for further study, including: Anquamine 401, Beckopox EH 613, OudraCure WB 8005, OudraCure WB 8006, and OudraCure WB 8007.

In case of excess of ferrosilicon, the whole vanadium in the produced hardener
binds into silicides, that causes increase of weight share of silicon in the metal.
In addition, BASF offers a broad portfolio of binders, light stabilizers and formulation additives for 2K PU coatings that can be perfectly combined with Basonat hardeners
for 2K Epoxy Systems"--Gerald Vandezande, Dow Coating Materials
The eight clearcoat systems are differing in matrices (polyacrylate polyol PAP or polyester polyol PEP), stabilizers (with or without HALS) and hardeners
(HDI, HDI/IPDI blocked or not blocked).
The molding compound was composed of epoxy resin, hardener
, filler, and other additives.
Common sources of moisture include fluxes, dirty tools, ingot and hardeners
, combustion by-products, and charge materials containing molding sand, binder and additives.
Broad line of epoxy hardeners
and catalysts offered, including aliphatic polyamines, aliphatic and aromatic polyamine adducts, anhydrides and polyamides.
