5 color temperature: 190 ~ 200 �
6 surface tension, 2% aqueous solution for 42 ~ 56 dyncm.
7 soluble in water and some solvents, such as the right proportion of ethanolwater, propyl alcoholwater, trichloroethane, etc.
Aqueous solution with surface activity.transparency is high, stable performance, gel temperature, different specifications of the products
different, solubility with viscosity change, lower viscosity, the greater the solubility, hpmc their different specifications
