Abstract
Titanates and zirconates bearing organic substituents can act as corrosion inhibitors when added to foamable compositions based on thermosettable synthetic resins such as epoxy resins. Combinations of organometallates containing certain specific types of substituents provide synergistic improvements in the properties of structural reinforcement foams obtained by heating and curing the foamable compositions.
