Polyetheramine (PEA) is a type of polymer with a polyether
structure as the main chain and an amine group as the terminal
active functional group. The chemical formula is C3n+3H6n+10OnN2.
Amino-terminated polyether has the following structure: x, y = 0-n.
Polyetheramine is obtained by ammoniating polyethylene glycol,
polypropylene glycol or ethylene glycol/propylene glycol copolymer
under high temperature and high pressure. By choosing different
polyoxyalkylene structures, a series of properties such as
reactivity, toughness, viscosity and hydrophilicity of the
polyetheramine can be adjusted, and the amine group provides the
possibility for the polyetheramine to react with a variety of
compounds. Its special molecular structure endows polyetheramine
with excellent comprehensive performance. Commercialized
polyetheramine includes a series of products with monofunctional,
bifunctional, trifunctional and molecular weight ranging from 230
to 5000. It has been widely used in many fields such as polyurea
spraying, large-scale composite material production, epoxy resin
curing agent and automobile gasoline detergent. English name:
amino-terminated polyoxypropylene; Polypropylene glycol
bis(2-aminopropyl ether); polyetheramine; Polyetheramines;
2-(aminooxy)propan-1-amine CAS: 9046-10-0, 39423-51-3 Molecular
formula: C3n+3H6n+10OnN2 Molecular weight: common products have a
molecular weight of 230 to 5000 Soluble in organic solvents such as
ethanol, glycol ethers, ketones, aliphatic hydrocarbons and
aromatic hydrocarbons. D-230 is soluble in water, D-400 is
partially soluble in water, and D-2000 is insoluble in water. The
exothermic temperature of the end-group polyether cured epoxy resin
is reduced, and the product is colorless and transparent, high
gloss, toughness, and heat shock resistance. Amino-terminated
polyether has high boiling point, low vapor pressure, low toxicity,
and is potentially irritating to the skin. LD50: 1660mg/kg (D-230),
500 (D-400), 450 (D-2000), 230 (T-403). Used as a toughening curing
agent for epoxy resin adhesives. It can be used alone or mixed with
ordinary polyetheramines. The reference dosage is 30-60 parts, and
the curing conditions are 80ºC/2h+125ºC/3h. Of course, it can be
cured at room temperature, but the bonding strength is not high.
Only D-400 and D-2000 are mixed at 50:25. After curing at room
temperature/7d, the peel strength is as high as 28.4kN/m and the
shear strength is 11.2mPa. In addition, E-51: D-230=100:30 or E-51:
D-400=100:64, with 4 parts of methanol as an accelerator, the epoxy
resin can be cured well at room temperature. Amino-terminated
polyether has low activity and longer construction time. Adding a
small amount of accelerator nonylphenol (10-20 parts per 100 parts
of epoxy resin) can significantly accelerate the curing reaction
speed and improve moisture resistance. Amino-terminated polyether
has low viscosity, colorlessness, good compatibility with epoxy
resin, long pot life and high bonding strength. Excessive use of
amino-terminated polyether will reduce the bonding strength of
epoxy adhesives. It can also be used as an active chain extender
for polyester. Also used as curing agent for polyurethane and
polyurea. Product namePolyetheramine
