Improved manufacturing processes

Carving out a technological lead enables the establishment of new standards and helps secure competitive advantages. This is why Cognis invests a great deal of its energy in the development of new processes such as phase inversion polymerization (PIP).

Aqueous epoxy resin systems are formulated through the addition of hydrophilic substances to the epoxy resin and hardener. Manufacturers can thus transform solid resins into PIT dispersions, as a result of which are able to emulsify even untreated, liquid epoxy resins and dispersive fillers.

Waterpoxy® 760 is based on this new phase inversion polymerization (PIP) process, a technology first described by Cognis. In this process, the epoxy emulsion is transformed during the polymerization and hardening phases from an O/W into a W/O emulsion, with aqueous cavities then preventing shrinkage as the oil-containing outer layer cures. In addition, this technology facilitates better penetration hardening at low temperatures.

Benefits:

  • Fine dispersity with oil droplets < 200 nm
  • Not affected by temperature
  • High thermodynamic stability
  • Extended storage life
  • Formulations with no or very little solvent
  • Based on natural, renewable raw materials
  • Almost completely biodegradable
