Pat-Add Coal 88
- CASE Ingredients Functions
- Coalescing Agent
Pat-Add Coal 88 is a highly efficient coalescing agent for dispersion paints, plasters and polymeric dispersions. PAT-ADD COAL88 reduces the MFFT (minimum film formation temperature), enabling proper film formation at lower temperatures. PAT-ADD COAL88 is offered as an odorless liquid, easy use and efficient at low dosages. Waterborne dispersion paints, plasters and polymeric dispersions.

- Properties
Coalescing agent PAT-ADD COAL88 optimizes coalescence of polymeric binder particles during paint film formation. The product is strongly adsorbed onto polymer particles, concentrating around the particle. During film formation, PAT-ADD COAL88 softens the polymeric particle, supporting the transition of the particles into a continuous film. As a result, maximum film strength for best mechanical properties such as abrasion resistance and scrub resistance is developed. Even under adverse drying conditions such as high temperatures, or low humidity, PAT-ADD COAL88 stays in the film long enough to provide proper film formation. Unlike classical coalescing agents, PAT-ADD COAL88 typically has no effect on the odor of the paint; enabling the formulation of odorless paints for indoor applications, hospitals, classrooms, nurseries, etc.

- Addition and Dosage
The optimal amount of PAT-ADD COAL88 is system related, but generally between 0.2 and 2.0% PAT-ADD COAL 88, based on the total weight of paint formulation. The product is best added during the let-down manufacturing stage. The optimum concentration depends on individual formulation and conditions our recommendation is to determine this experimentally.
