A brief introduction to organic bismuth

A brief introduction to organic bismuth
Organic bismuth compounds have green and safe properties such as low cost, easy to handle, low toxicity and low radioactivity. In the past 10 years, both in the synthesis of new organic bismuth compounds and the research of organic bismuth compounds in organic synthesis, catalysts and biopharmaceuticals, are in a rapid development stage. Bismuth has been produced in advanced countries for over 30 years and has been supplied to the European and American markets for many years. These environmentally friendly bismuth catalysts can be room temperature cured or heat cured and are an excellent alternative to toxic lead, mercury and tin products.

Introduction to Bismuth Organic

1. Safe and environmentally friendly alternative to lead mercury and tin, which is being legislated away.

2. Better hydrolytic stability, reduced selectivity for water reaction, reduced by-reaction of water with NCO groups in aqueous PU dispersions.

3. Promotes NCO/OH reaction, avoids NCO side reactions and reduces CO2 production.

4. In one-component systems, freeing the water-shielded amine rather than promoting the reaction of NCO with water.

5. The combination of bismuth and zinc has a synergistic effect, allowing more flexibility in formulation and production, reducing energy consumption and increasing profitability.

6. Can be used alone or in combination with amines or other organometallic compounds; Organic bismuth is an environmentally friendly, odourless, non-foaming catalyst for polyurethane runways:

Description of product properties:

The appearance of this product is light yellow transparent liquid, metal content 19.7-20.7%; density 1.01g/cm3(25℃), viscosity 210mPa.s(25℃); with special compound odor, easily soluble in general polyurethane raw materials such as polyether, polyester polyol, etc.

This product does not contain eight heavy metals, azo, o-phenylates and other toxic components, the use of this product synthesis of polyurethane materials, can pass the United States and the European Union and other strict environmental regulations. It is an ideal alternative to traditional catalysts such as organotin, mercury and lead.
