Jefflink 555 chain extender is a mixture of fatty amine, it is mainly used for fast curing caulking polyurea elastomer, can also be combined with other materials, used for spraying polyurea, reduce the curing speed. The product design and end amino polyether combination. It contains alcohol.

Jefflink 754 is a new type of alicyclic double secondary amine (N, N '- double para amyl hexane diamine, CAS number 156105-38-3), primary amine content of about 0.1% (value of primary amine and tertiary amine value tendency is not greater than 0.30 g), room temperature is low viscosity liquid, has good compatibility with poly olefin amine oxide, is not sensitive to moisture, low molecular weight, slower for amine curing system.

As chain extender with stable aliphatic polyurea system, prolong operation time. Similar to spray polyurea performance can be obtained with static mixer construction sealant. Slow curing of amine chain extender is also used to fine-tune the reactivity of spraying system, control surface appearance, improve physical properties.

Jefflink 7027 is a low viscosity aliphatic amine mixture blocking, containing a small amount of primary amine tendency (0.54 g), used for aliphatic or aromatic polyurea system, these polyurea can be used for industrial coatings, sealant and coating glue.




Chinese name: Diethyl toluene diamine(DETDA)

Diethyltoluenediamine Uses:

The product is identical to Ethancure 100 and Lonza DETDA 80, DETDA is very effective polyurethane elastomer chain extender; also be used as polyurethane and epoxy resin curing agent, epoxy resin of an antioxidant, industrial oils and lubricants . In addition, also as intermediates in organic synthesis.Especially for the RIM (reaction injection molding), is important in the field of spray polyurea chain extender species. Also can be used for casting polyurethane elastomer (CPU) and a curing agent, epoxy curing agent, epoxy resin of antioxidants, lubricants and industrial oils other antioxidants.


Copolyether diamine Jeffamine HK - 511 structural formula is as follows:

(XTJ HK - 511-511) including EO and PO link, 220, the average relative molecular mass is about 8.2 tendency for primary amino content/g, colorless to light yellow, slightly turbid liquid viscosity (25 ℃) 100 mpa s., relative density 0.984 (20 ℃), the vapor pressure of 133 pa / 95 ℃, 1% aqueous solution pH value of 11.2, in the water solubility of > 10%.

Jeffamine XTJ - 504 chemical name is 3, 6 - two oxygen eight methylene diamine (triethylene glycol amine), relative molecular mass, 148 is also a dual primary amine, amino without steric hindrance, because a higher reactivity. Slightly turbid it is colorless to pale yellow liquid, total amino acids is about 13.4 tendency for g, 8 mpa s. viscosity (25 ℃), relative density 1.01 (20 ℃). These aliphatic binary amine high activity, more commonly used in epoxy resin curing agent, can also be used for polyurethane - urea system.

Haerter DT is a place of aromatic diamine, relative molecular mass of about 180, the molecular structure is unknown. Its viscosity is 200 + 40 mpa s., amine value (630 + 10) mgKOH/g, > 130 ℃, flash point density (20 ℃) is about 1.02 g/mL, water < 0.1%. Haerter DT is mainly used for solvent-free polyurethane coating, as a curing agent of high-performance solvent-free two-component polyurethane coating, high flexibility, can be used to repair concrete cracks sealing material, spraying polyurethane elastomer and one-component thixotropic coating, etc.

A variety of diamine extender chain agent (agent), can be used in polyurethane, polyurea system.

ADA 180 2 ethyl toluene diamine isomer mixing the low viscosity of polyurethane and polyurea chain extension agent, also used for compound (DETDA) epoxy resin curing agent. ADA 222 contains a kind of MOCA aromatic liquid aromatic amine chain extension agent, the average relative molecular quality amine compounds 222. Type is mainly used for pouring polyurea (polyurethane) ADA 420 contains a kind of MOCA aromatic liquid aromatic amine chain extender, the average relative molecular mass amine compounds, 420. It is mainly used for casting type polyurea (polyurethane) ADA 580.
