ABSTRACT:
Phenolic resins and processes of making these phenolic resins that are useful for making binders for mineral wool insulation products are disclosed. The addition of a boron salt early in the process of making these phenolic resins leads to enhanced properties such as a reduction in the amount of tetradimers and an improvement in the stability of both the base resin and the pre-react.
