Stannous Octoate Alternatives

Introducing two commercially available, market tested, 2-ethylhexanoic acid-free catalyst options Fomrez® 90 and Fomrez® 91, alternatives to stannous octoate for use in manufacturing polyurethanes.


Fomrez® 90 is a high efficiency, oxidatively stable catalyst for polyurethane production, particularly for slabstock foam. It results in the target polymerization rate and mechanical properties at significantly reduced usage levels.



Fomrez® 91 is an oxidatively stable catalyst for polyurethane applications. It results incomparable-to-superior polymerization rate, cost-performance characteristics and mechanical properties of the formed polyurethane articles.
