DESCRIPTION
OXTL-300, as non-ionic dispersant, is used for aqueous coating systems, printing inks and adhesives. It is standard additive for binder-free pigment concentrates. It can reduce viscosity and improve gloss. It is also low-foam, no need to add defoamers in grinding. it is especially recommended for use in organic pigment and carbon blacks for its excellent color spreading effect. For medium and high carbon black pigment, its solid content can be made to 35% and particle size below 200 nanometers.
Organic pigment
Solid content: 90% Viscosity: 18.5s

APPLICATION GUIDELINES
Aqueous ink and coating, aqueous universal pigment
SPECIAL FEATURES AND BENEFITS
The additive deflocculates pigments by means of steric stabilization. As a result of the small particle sizes of the deflocculated pigments, high levels of gloss can be achieved and the color strength is improved.
Transparency and hiding power are also increased and viscosity is reduced. In this way, the flow characteristics are also improved and higher pigment loading is possible.
The additive is especially suitable for producing binder-free, stable pigment concentrates with a pigment content of 30-60 %. These pigment concentrates can be let down with standard aqueous binders.

RECOMMENDED ADDITION LEVEL
Amount of additive (as supplied) based upon pigment:
Organic pigment: 10%—30%
Carbon blacks: 10%—50%
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
PROCESSING INSTRUCTIONS
Grinding should only take place in water and grinding resin. Mix the additive with water and only add the pigments once the additive has been homogeneously and uniformly distributed.
