Product Applications
  • Calfax® DB-45 offers magnificent wetting, coupling, solubilizing, and emulsification performance making it an ideal surfactant choice for many applications.
  • Latex Emulsification: The high surface activity and the high electrolyte tolerance of Calfax® DB-45 make it the surfactant of choice for the manufacture of latex emulsions for adhesives and foam rubber. These properties allow the user to operate the emulsification process under conditions that would not be usable with conventional surfactants, permitting greater control over the latex’s molecular weight and particle size. Calfax® DB-45 produces consistent polymerizations with excellent thermal and mechanical stability.
  • Agricultural Chemicals: The high emulsification and excellent water solubility of Calfax® DB-45 can aid the formulator of agricultural emulsions by providing a broader blend of anionic to nonionic in hard to emulsify pesticides and herbicides.
  • HI&I Cleaners: Calfax® DB-45 is uniquely stable and effective in acid, alkali, chlorine and peroxy bleach as well as formulations containing electrolytes and builders. Calfax® DB-45 is perfect for streak-free cleaning. It is also the surfactant of choice for heavy duty cleaners, bleach and peroxy cleaners, toilet bowl cleaners, glass, and all-purpose cleaners as well as concentrated 2X – 4X laundry and dish wash detergents.
