The acid value of dimer acid ranges from 194 to 200.
Dimer acid is an important oil and fat chemical, and its acid value is an important indicator of its chemical properties. The acid value usually refers to the number of milligrams of potassium hydroxide (KOH) required to neutralize the acidic substances in 1 gram of sample. For dimer acid, its acid value ranges from 194 to 200, which indicates that dimer acid has a certain acid strength. In addition, the viscosity of dimer acid is generally between 5000 and 7000, and the color APHA value is 80. These physical and chemical properties jointly determine the characteristics and effects of dimer acid in industrial applications.
The application of dimer acid is very wide, including but not limited to coatings, surfactants, lubricants, printing inks, hot melt adhesives and other industrial fields. Its excellent solubility and chemical stability make dimer acid one of the indispensable raw materials in these fields. In addition, high-purity dimer acid products, with a content of ≥98%, a monoacid content of ≤0.5%, and a trimer acid content of ≤2.0%, further guarantee its performance and effect in specific applications.
