DeCAL 2077

• DeCAL 2040E is an ideal dispersing agent for a wide range of water borne coatings.
• DeCAL 2040E can be used as supplied.
• Compared with inorganic dispersing agents e.g. polyphosphate products, the organic polymer based DeCAL 2040E provides improved storage stability of both the pigment dispersion and the formulated paint. There is little or no adverse reaction to high temperatures or pH changes.

DeCAL 2077 finds use in other industries:

Textiles :

• As a polymeric dispersant and protective colloid. Used to aid wash off of reactive dyeings and prints on cellulosic substrate.

Mining and Mineral Processing:

• As an antiscalent in aqueous based mineral processing and the sugar industry, preventing the onset of inorganic precipitation and preventing the fouling of heat exchangers.

Oilfield uses:

• As a mineral dispersant for drilling fluids and an anti-scalent for aqueous fluids. Devine Chemicals also offer polyacrylates in the ammonium salt or free acid forms and also a range of differing copolymers and molecular weights

"

• It is recommended to add the pigment to water containing the dispersing agent with stirring as opposed to addition of the dispersing agent to a pigment slurry. In general, the pH of the final preparation should be in the region of 8.5 to obtain optimum dispersing efficiency. 
• The optimum amount of dispersing agent required to form a stable dispersion strongly depends on a pigment’s chemical nature, the particle surface and shape.
• The polymer base of the latex also plays a very important part in the stability equation. In general, significant overdosing may deteriorate the coatings properties (e.g., 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 the batch-to-batch variations of the demands of a specific pigment or latex type it is recommended that the formulator uses 1.5 - 2.0 times the determined optimum level of the dispersing agent. 
• DeCAL 2077 has been successfully used to produce a wide range of aqueous slurries and dispersions. Suitable substrates include calcium carbonate, kaolin/china clay, dolomite, ferrite, magnesium hydroxide, mica, satin white, talc, titanium dioxide, zinc oxide etc.

DeCAL 2077 is supplied in 270kg nett drums or 1250 kg IBC’s.
