The global isocyanates market is witnessing consistent demand in the construction industry due to its reactive chemical properties and its usage in the production of adhesives, foams, and elastomers.
Dow and Univar Inc. recently announced that Dow has selected Univar Solutions as a key North American channel to market, distributing Dow’s product portfolio of polyols and isocyanates.
Isocyanates react with compounds that have active hydrogens. For example, in coating applications, isocyanates are typically reacted with polyols to form polyurethanes, or with primary and secondary amines to form polyureas. Catalysis of the polyol/isocyanate reaction, which is often required to develop sufficient cure response, can be achieved with a variety of compounds.
What types of chemical structures could be built into a polyurethane adhesive to optimize heat resistance? Can you make any formulation recommendations?
As a partner in the value chain, adhesive and sealant manufacturers with products containing isocyanate material at a minimum should consider notifying their customers of the existence of this new OSHA program.
