- Applications
- DeCAL 2078 is an ideal dispersing agent for a wide range of waterbased systems.
- DeCAL 2078 can be used as supplied and is particularly suitable for use as a dispersion aid in dry powder blends and finds wide use in areas such as textured coatings and powdered adhesives.
- Compared with inorganic dispersing agents e.g. polyphosphate products, the organic polymer based DeCAL 2078 provides improved storage stability of both the pigment dispersion and the final formulated product. There is little or no adverse reaction to high temperatures or pH changes.
- Incorporation in Formulations
- When preparing dry powder blends DeCAL 2078 is simply blended with the pigments and fillers at the correct dosage. In general, the pH of the final preparation should be in the region of 8.5 to obtain the best dispersing efficiency.
- The optimum amount of dispersing agent required to form a stable dispersion strongly depends on a pigments chemical nature, the particle surface and shape. In general, significant overdosing may deteriorate the coatings properties, eg water resistance, and also generates an economic disadvantage. Likewise, insufficient dispersing agent will lead to instability on storage.
- In common with other dispersing agents, because of batch to batch variations of the demands of a specific pigment it is recommended that the formulator uses 1.5 – 2.0 times the determined optimum level of the dispersing agent.
