Disponer 904S

Disponer 904S by Elementis is a wetting and dispersing agent. It is solution of polycarboxylic acid polymer with modified polysiloxane. It is an additive for polar and non-polar systems. It is highly effective in preventing floating of titanium dioxide pigments in paint formulations also containing colored pigments.

• It prevents hard settling deposits when basic pigments and carbonate fillers are used.
• In contrast to certain silicone oils, Disponer 904S does not as a rule produce cratering.
• It is a very effective flow promoter and eliminates surface disturbances in the film when added at the proper level.
• In addition, the scratch resistance and slip properties of the film are considerably improved.
• It can be used in both water-thinnable and solvent-containing systems.
• It works independent of the binder system to a very great degree, allowing a wide range of use.
• It is used in ready paints, epoxy paints, gravure printing inks/ screen printing inks and coatings.
• Recommended dosage level is 0.5-3.0% for inorganic pigments and 2-5% for organic pigments based on pigment.
• Disponer 904S has a shelf life of 2 years from date of manufacture.
