ABSTRACT:
The invention provides an improvement to the useable lifetimes of phenolic-epoxy, phenolic-benzoxazine, phenolic-epoxy-benzoxazine mixtures and other phenolic mixtures through the use of protected phenolics, where a phenolic compound, polymer, or resin is released on demand by the addition of a deblocking agent.
