amine cured-epoxy matrices
... Epoxy resins can be cured with a variety of compounds called curing agents which are also known as curatives, hardeners, or converters. Of the many classes/types of curing agents, amines are most widely utilized as curing agents in epoxy matrices for high performance composites. This produces a hete ...

BSA + TMCS + TMSI - Sigma
... Silylation is the most widely used derivatization procedure for GC analysis. In silylation, an active hydrogen is replaced by an alkylsilyl group, most often trimethylsilyl (TMS). Compared to their parent compounds, silyl derivatives generally are more volatile, less polar, and more thermally stable ...

Amines have a relatively high solubility in water because of the hydrogen bonding that occurs in primary and secondary amines. Tert ...

The relative stabilities of high oxidation state “homoleptic” or “peralkyl” compounds such as M[CH2Si(CH3)3]4, M(CH2C6H5)4, and M[CH2C(CH3)3]4 (M = Ti, Zr, or Hf; Fig 2), were rationalized on the basis of the fact that unlike a compound having an ethyl ligand, th ...
