QC-E100, known as Diethyl-toluene-diamine (DETDA), is an aromatic diamine liquid curing agent, also commonly known by the brand names Ethacure 100 and Lonza DETDA 80, and Nitroil ADA I80 in polyurea and polyurethane (PU) industry.

Properties

Substance name: Diethyl Toluene Diamine
CAS No.: 68479-98-1
Molecular formula: C11H18N2
Molecular weight: 214.36
UN code: 3082
HS code: 2921519090

Advantages

♦ Low viscosity, easy to handle. Its liquidity character enables manufacturers to perform room temperature processing and curing.

♦ Excellent dynamic properties comparable to MOCA, but with less toxicity and dust concerns in the production plant.

♦ Fast curing, leaves little room for environmental factors like humidity and oxidation to affect the quality of products featuring DETDA.

Application

1. Used mainly as curing agent for Polyurea spraying system in construction and building materials for a long lasting protection of all surfaces. It’s an ideal solution demanding for quick, efficient and lasting coating/sealing.

2. Used as crosslinker and chain extender of polyurethane and epoxy resin, antioxidant of epoxy resin, industrial oil and lubricants.

3. DETDA is also applied as intermediate in organic synthesis.
