Polyether amine coating crosslinking agent

Polyether amine coating crosslinking agent polyether amine (PEA) is a kind of main chain structure of polyether, end of active functional group for amino polymers. End amino polyether has the following structure: the x, y = 0 - n. Polyether amine by polyethylene glycol, ethylene glycol/poly (propylene glycol or propylene glycol copolymer ammoniation gets under high temperature and high pressure.

By selecting different alkyl oxide structure, adjustable polyether amine of reactivity, toughness, viscosity, and hydrophilic and a series of performance, and amino provides the possibility of polyether amine react with a variety of compounds.

Its special molecular structure gives the polyether amine excellent comprehensive performance, the current commercial polyether amine including single faculties, bifunctional, three faculties, molecular weight from 230 to 5000, a series of products. In spray polyurea, large composite materials and epoxy crosslinking agent has been widely applied in a broad range of areas.

Low end amino polyether viscosity, colorless, it has good compatibility with epoxy resin, long period, high bonding strength. . End group polyether cross-linked epoxy resin exothermic temperature is reduced, the product is colorless transparent, high gloss, toughness, heat shock. End amino polyether high boiling point, low steam, low toxicity, potentially irritating to the skin.

Polyether amine (PEA) : is a kind of main chain structure of polyether, reactive functional groups at the end of amino polymers. End amino polyether has the following structure: the x, y = 0 - n. Polyether amine by polyethylene glycol, ethylene glycol/poly (propylene glycol or propylene glycol copolymer ammoniation gets under high temperature and high pressure. By selecting different alkyl oxide structure, adjustable polyether amine of reactivity, toughness, viscosity, and hydrophilic and a series of performance, and amino provides the possibility of polyether amine react with a variety of compounds.

Its special molecular structure gives the polyether amine excellent comprehensive performance, the current commercial polyether amine including single faculties, bifunctional, three faculties, molecular weight from 230 to 5000, a series of products. In spray polyurea, large composite materials as well as curing agent for epoxy resin has been widely applied in a broad range of areas.

Polyether amine soluble in ethanol, glycol ether, ketone, fatty hydrocarbons, aromatic hydrocarbons and other organic solvents. Soluble in water, D - 230 D - 400 partly soluble in water, D - 2000 does not dissolve in water.




Chinese name: Diethyl toluene diamine(DETDA)

Diethyltoluenediamine packing： net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).


End group polyether epoxy resin curing exothermic temperature is reduced, the product is colorless transparent, high gloss, toughness, heat shock. End amino polyether high boiling point, low vapor, low toxicity, potentially irritating to the skin.

LD50:1660 mg/kg (D - 230), 500 (D - 400), 400 (D - 2000), 230 (T - 403).

Used as the toughness of epoxy resin adhesives curing agent, and can be alone or mix with the ordinary polyether amine, reference dosage of 30 ~ 60, curing condition 2 h + 80 ℃ / 80 ℃ / 3 h.

Can also be room temperature curing, of course, but the bonding strength is not high, only D - 400 and D - 2000 press brought mixed use, after / 7 D at room temperature curing, peel strength is as high as 28.4 kN/m, shear strength 11.2 mPa.

Another 51: E - D - 230 = 230:51:30 or E - D - 400 = 400, 64, 4 copies of methanol as promoter, room temperature curing epoxy resin adhesive well. End amino polyether activity is low, the construction for a long time, join the promoter nonylphenol small (by 100 epoxy resin with 10 ~ 20) can obviously accelerate the curing reaction speed, and can improve the moisture resistance.

Low end amino polyether viscosity, colorless, it has good compatibility with epoxy resin, long period, high bonding strength. If end amino polyether overuse, can reduce the bonding strength of epoxy adhesives. Also can be used as the activity of polyester chain extender. Also used for polyurethane and polyurea curing agent.
