TEDA-DPG is the liquid, easy-dose form of the benchmark gelling catalyst — triethylenediamine (TEDA/DABCO) dissolved at 33% in dipropylene glycol for accurate metering in polyurethane systems. Identity: CAS 280-57-9.
What it is
TEDA-DPG (TEDA CAS 280-57-9, in dipropylene glycol) is a clear liquid solution, typically 33% active. It delivers TEDA’s strong gelling action in a pourable, pumpable form that is easy to meter and blend.
How it catalyzes
It provides the same strong gel (urethane) catalysis as solid TEDA, with the dipropylene-glycol carrier acting as a compatible diluent (and minor chain extender). The liquid form simplifies handling and dosing in production.
Applications
TEDA-DPG is used in flexible and rigid foam and CASE where a liquid gelling catalyst is preferred, balanced with a blowing catalyst. The neat solid is TEDA.
Forms, grades and handling
Supplied as a clear liquid solution (typically 33% TEDA in dipropylene glycol). Properties are typical reference values; the Certificate of Analysis (CoA) for the lot you buy governs. Amine catalysts are typically corrosive and have a strong odor — handle per the current Safety Data Sheet (SDS). Each lot ships with CoA, TDS and SDS.
Bulk supply and RFQ
RawSource sources TEDA-DPG 33% Catalyst Solution direct from producers in bulk, with CoA, TDS and SDS per lot. Tell us your system (flexible/rigid foam, CASE), the reaction balance you need (gel vs blow), and any low-emission requirement, and we will quote the right catalyst or blend. See the full range and gel/blow selection logic in the polyurethane catalysts guide.

Frequently Asked Questions
What is TEDA-DPG 33% solution used for?
TEDA-DPG is triethylenediamine (TEDA/DABCO, CAS 280-57-9) dissolved at 33% in dipropylene glycol — a liquid gelling catalyst for polyurethane that is easy to meter, used in flexible/rigid foam and CASE balanced with a blowing catalyst.
How is bulk TEDA-DPG solution supplied and quoted?
RawSource supplies TEDA-DPG solution in bulk with CoA, TDS and SDS per lot. Pricing is quote-based on grade and volume; submit an RFQ with your PU system and the gel/blow balance you need.
What is the REACH and TSCA regulatory status of TEDA-DPG 33% Catalyst Solution (Triethylenediamine in Dipropylene Glycol)?
TEDA-DPG 33% Catalyst Solution (Triethylenediamine in Dipropylene Glycol) (CAS 280-57-9) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 205-999-9).
