Texanol Ester Alcohol is a slow evaporating, water-insoluble coalescing aid for latex paints.
It provides good performance characteristics, such as scrub resistance, color development, and package stability in paints.
It is an excellent coalescing aid for emulsion polymers and has excellent hydrolytic stability, allowing it to be used with a wide variety of latex emulsions including high pH acrylics.
When added to an emulsion paint, Texanol is absorbed by the emulsions polymeric particles, softening them and causing complete fusion when the paint film dries.
Since Texanol is insoluble in water and therefore not in the water phase, applying the paint over a porous substrate does not result in reduced coalescing efficiency because Texanol is not absorbed along with the water. |
