Descripción

General description

Dabco^® 33-LV, as a tertiary amine catalyst, has various uses in polymer applications. It is widely utilized as a catalyst in the production of flexible and rigid polyurethane foams via the reaction between isocyanates and polyols. It helps control the gel time, improve foam rise, and optimize the physical properties of the final polyurethane foam. These foams are commonly used in insulation materials, automotive applications, construction, and packaging applications. Additionally, DABCO^® 33-LV can form a self-assembled monolayer (SAM) on a variety of substrates, making it a useful bidentate ligand in the field of polymers.

Dabco^®33-LV (Db) is a gelling catalyst and a bidentate ligand that forms a self-assembled monolayer (SAM) on a variety of substrates. It functionalizes the surface and immobilizes the surface atoms.

Application

Dabco^® 33-LV (Db) can be used:

• As a gel catalyst to promote the gel reaction in the production of flexible and rigid polyurethane foams, microcellular foams, coatings, and elastomers. Dabco®33-LV is used to accelerate the isocyanate-polyol reaction.
• In the synthesis of anion exchange membranes (AEMs) via electrospinning, contributing to the crosslinking between the polymers and the mechanical stability of the membrane. AEMs are further used in fuel cells, water electrolysis, redox flow batteries, and electrolyzers.
• Db can be used in the preparation of epoxy based soybean oil for the formation of polyurethane foams.
