ABSTRACT:
Curable compositions comprising phenolic resin, polyisocyanate, catalyst, and petroleum oil. The phenolic resin is soluble in the petroleum oil, but during reaction of the ingredients the petroleum oil separates as a uniform dispersion of minute droplets entrapped within the reaction product. The compositions are insensitive to the presence of water and produce dimensionally stable cured products, making them especially useful as wood-patching compositions.
