ActivePlastics—Phenloic resins—Determination of pH
塑料 酚醛树脂 pH值的测定
Application Summary AI generated
This standard specifies a method for determining the pH value of phenolic resins, which is critical for assessing their reactivity and curing behavior. It is applied in the plastics and rubber industries, particularly for quality control during the production and formulation of phenolic resin-based adhesives, molding compounds, and coatings. The test is conducted in a laboratory setting using a pH meter on an aqueous extract of the resin.
