This is the 70/30 solution of the blowing catalyst BDMAEE in dipropylene glycol — the easy-handling, diluted form of the strongly blow-selective flexible-foam catalyst. Identity: CAS 3033-62-3.
What it is
BDMAEE 70/30 (BDMAEE CAS 3033-62-3, in dipropylene glycol) is a clear liquid, typically 70% active in a dipropylene-glycol carrier. The dilution moderates handling of the very active neat amine.
How it catalyzes
It delivers BDMAEE’s strong blow catalysis (water + isocyanate → CO2) in a diluted, easier-to-meter form, with the glycol as a compatible carrier. Balanced with a gelling catalyst.
Applications
Used in flexible slabstock and molded foam where the diluted catalyst is preferred, with a gelling catalyst such as TEDA. The neat form is BDMAEE.
Forms, grades and handling
Supplied as a clear liquid solution (typically 70% BDMAEE 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 Bis 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 BDMAEE 70/30 solution used for?
It is bis(2-dimethylaminoethyl) ether (BDMAEE, CAS 3033-62-3) at ~70% in dipropylene glycol — the diluted, easy-handling form of the strong blowing catalyst for flexible polyurethane foam, balanced with a gelling catalyst.
How is bulk BDMAEE 70/30 solution supplied and quoted?
RawSource supplies BDMAEE 70/30 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 Bis(2-dimethylaminoethyl) ether in Dipropylene Glycol (70/30)?
Bis(2-dimethylaminoethyl) ether in Dipropylene Glycol (70/30) (CAS 3033-62-3) 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 221-220-5).
