Plastics - Liquid phenolic resins - Determination of water miscibility

1 Scope

This standard specifies a method for the determination of the miscibility of water with liquid phenolic resins.

This standard is applicable to liquid phenolic resins. Water miscibility is dependent on the environmental conditions under which the resin is stored and the degree of condensation of the resin.
