A structural adhesive which is particularly useful in vertical substrates is composed of a mixture of two components, the first component being an epoxy resin component comprising a poly epoxide and a polyisocyanate which has been allowed to react with less than an equivalent weight of a polyamine which is a primary or secondary polyamine and the second component being a hardener for the polyepoxide comprising a mixture of primary, secondary and tertiary amines, amido amines and phenolics.
