T-Cat-110: Stannous Octoate Tin Catalyst

A clear to straw colored viscous liquid, Stannous Octoate is used as a gelling catalyst in the manufacture of polyurethane foam.

PURPOSE:

In the manufacture of polyurethane foam, the gelation reaction between the polyol and isocyanate is catalyzed through the use of organometallic catalysts (primarily Tin compounds). For flexible slab-stock foam, Stannous Octoate is the preferred catalyst. By varying the concentration of Stannous Octoate in the formulation, a balance can be achieved between the gelation and the blowing reaction.

APPLICATION:

Stannous Octoate is the standard gelling catalyst for use in the manufacture of flexible slabstock foam. It can also be used as a catalyst for molded polyurethane foams, polyurethane coatings and sealants.

ADVANTAGES:

Gulbrandsen’s T-Cat-110 Stannous Octoate is manufactured under ISO 9001 quality control standards, resulting in a product with uniform tin levels, consistent performance and no undesirable color or odor being imparted to the foam. While packaged under a nitrogen atmosphere, stabilizers are also added to minimize oxidation that may occur due to accidental exposure to air, ensuring that the product will perform reliably. Gulbrandsen can also provide Stannous Octoate in dilute mixtures to various ratios with Diisononyl Phthalate (DINP), Dioctyl Phthalate (DOP), Mineral Oil, and Natural Polyol.
