Application and performance
Catalyst for RTV
IOTA-980 used as a catalyst in the vulcanizing cure of silicones at room temperatures.
Polyurethane
IOTA-980 catalyst finds greatest use in the manufacture of rigid polyurethane foams. In demanding applications where amine catalysis alone is inadequate, the extra activity obtained by the synergistic combination of organometallics like IOTA-980 catalyst with an amine catalyst permits the required rapid catalysis. Examples include high-density structural foam, sprayup wall insulation and rigid boardstock run at high line speeds. Even when used at levels as low as 0.1 phr based on polyol, IOTA-980 catalyst is especially effective in promoting rapid gel and tack-free times.
Tetravalent diorganotins like IOTA-980 catalyst are known throughout the industry as promoters of the reaction of isocyanates with polyols to form polyurethanes, and of the secondary crosslinking reactions to form allophonate and biuret linkages.
Thermoplastics 
The grafted polyethylene can then be immediately crosslinked in the presence of a tin catalyst.
Other applications
Polyamide and phenolic resins, light and heat stabilizers.
