  • Patent number: 3956204
    Abstract: Phenolic resin antipunk systems for thermal insulation, characterized by stability and a low level of volatile pollutants. The aqueous resin systems contain a resole component and an antipunk component. They are prepared by a three-step reaction which controls the degree of reaction, the molecular weight and the water tolerance of the resole component. Stability is promoted by inhibition of the crystallization of bis(4-hydroxy-3,5-dimethylolphenyl) methane.
