Abstract
The cure rate of phenol-aldehyde resins is accelerated by conjoint use of a cyclic carbonate cure accelerant and an amine cure accelerant. The cure rate is accelerated still further by addition of a resorcinol source to resin comprising a cyclic carbonate and an amine cure accelerator. Also, cured resins made in accordance with the method.
