Organic Bismuth Krbi A1 A3 A4 - China

price: contact company for price

alais: Organic Metal Catalyst, Bismuth Carboxylate

Mixture, Green Polyurethane Catalyst Enviromental Friendly Organo-

Metallic Polyurethane Catalyst


1. Selective polyurethane gel catalysts;

2. Compared with Tin catalysts, it has better selectivity to NCO, and end products’

mechanical performance is better;

3. Induction time is short, viscosity increases gradually.


1. Safe & Environmentally- friendly catalysts, can replace Plumbum( Pb) & Mercury( Hg)

catalysts and Tin catalysts which are being abolished by legislation;

2. Bi catalysts have a better stability to hydrolysis resistance than tin catalysts, reduce

reaction selectivity with Water, reduce side reactions of NCO group and Water reaction

in Water- borne PU dispersing agent;

3. Promote the reaction of NCO/ OH , avoid side reactions of NCO and reduce CO2 form;

4. In one- component system, emancipate the amine shielded by water, rather than

promote the reaction of water and NCO;

5. Combination of Bismuth & zinc has synergy effect, making formulation and production

more flexible, reducing energy consumption and increasing profits;

6. Can be used alone, or used together with amine or other organic metal compounds

as auxiliary catalyst.
