Beakers - About

In latex paints, coalescing aids reduce the glass transition temperature (Tg) allowing the polymers to flow together and form a film. Since coalescing aids are volatile, they evaporate out of the film thus allowing the polymer to return to the original Tg.

A coalescing aid must fulfill three criteria:

  • Be compatible with base polymer of the system.
  • Lower the minimum film-formation temperature (MFFT).
  • Evaporate at a lower rate than water.

xF Technologies offers a range of solvents that can function as efficient coalescing aids and two examples are triethylene 408 (TEG 408) and methoxyethyl 408 (ME 408).
