Is Diethylenetriamine the same as EDA, TETA or a formulated epoxy hardener?

No. DETA is the specific triamine with CAS 111-40-0. EDA and TETA have different amine functionality, while a formulated hardener may also contain adducts, diluents or other components. They are not interchangeable by name, weight or volume.

Can neat DETA replace a formulated epoxy curing agent on a one-to-one basis?

No. A curing-agent change must be calculated from the actual epoxy equivalent and active-amine-hydrogen basis of the supplied materials. A formulated hardener is not defined by DETA content alone, so equal-weight replacement can change cure behaviour and final properties.

Which DETA grade controls should be aligned for industrial use?

Confirm assay, water, colour, amine value and the relevant impurity limits, together with test methods. These values should match the intended reaction or curing specification; an assay result alone does not establish equivalent DETA for every downstream process.

Diethylenetriamine (DETA) CAS 111-40-0

Diethylenetriamine (DETA, CAS 111-40-0, EC 203-865-4) is a reactive triamine used in epoxy-curing chemistry, polyamide synthesis, chelating agents, gas treatment and corrosion-inhibitor intermediates. It is distinct from Ethylenediamine (EDA), TETA, TEPA and formulated hardeners. Confirm assay, water, color, amine value, relevant impurities, packaging and transport requirements for the offered material against the current TDS, COA and SDS. DETA is corrosive and requires compatible equipment, moisture control and handling procedures based on the current SDS.

Product Overview

Diethylenetriamine (DETA, CAS 111-40-0, EC 203-865-4) is a reactive triamine intermediate used in epoxy-curing systems, chelating agents, gas treatment, polyamide synthesis and corrosion inhibitors. It is distinct from EDA, TETA, TEPA and formulated hardeners. For the offered material, confirm assay, water, color, amine value, relevant impurities and packaging. DETA is corrosive and hazardous by inhalation, ingestion and skin contact, and it may cause skin sensitization; prevent moisture and carbon-dioxide uptake and follow the current SDS.
