Armocure aliphatic polyamines provide flexibility, water resistance, solvent resistance, and low viscosity in casting and coating, and also recommended for laminating.
Broad line of epoxy hardeners and catalysts offered, including aliphatic polyamines, aliphatic and aromatic polyamine adducts, anhydrides and polyamides.
Offers modified aliphatic amine blends for replacing MDA-type hardeners.
Apco 2330 is a 100%-aromatic epoxy curing agent containing no MDA; Apco 2180, an aliphatic mine, is a room-temperature curing agent; Apco Safe-T-Poxy 2183 is a nonirritant, room-temperature hardener; and Apco 2320, an aromatic amine, is a high-tempera-ture hardener.
Leading HCS suppliers do not differentiate SBPs in North America, and define them as aliphatics
with narrower boiling ranges for specific applications that do not necessarily require an ASTM Stoddard solvent.
The column was then sequentially eluted under vacuum with pentane, benzene, ethyl acetate and methanol to produce aliphatics, aromatics, ester and polar fractions, respectively.
The pentane (1 and 2), benzene, ethyl acetate, and methanol eluents represent the fractions containing aliphatics, aromatics, hetero-atom containing (ester), and polar compounds, respectively.
The addition of steam caused some of the organic material that remained in shale during retorting in a nitrogen atmosphere as heavy material by the aromatisation of the oil to produce oils which contain more aromatics and less aliphatics.
We estimated the internal dose of HCs in fuels and solvents by measuring their levels in exhaled breath, including the sum of aliphatic HCs ([C.
The principal jet fuel used by the USAF, JP-8, is a mixture of petroleum distillates composed primarily of aliphatic and aromatic HCs in approximately a 6:1 ratio (Pleil et al.
Therefore, we estimated internal doses of aliphatic and aromatic HCs from solvents and fuels in mixed-exhaled breath samples collected from 63 participants.
