titanium dioxide Wetting And Dispersing Agent
, byk 110 Wetting And Dispersing Agent
GENERAL DESCRIPTION
Wetting and dispersing agent for solvent-borne and solvent-free coatings and printing inks,
stabilizes inorganic pigments, especially titanium dioxide. Significantly reduces the viscosity
of abrasives.
PRODUCT DATA
Chemical composition: Copolymer solution with acidic groups.
Typical physical and chemical data:
The data given on this data sheet are typical values and are not technical specifications of the
product.
Appearance: Water-white to light yellow liquid
Acid value (mg KOH/g) 50-80
Density g/cm³ (23℃) 0.90-1.10
Viscosity cps (25℃) 5-250
Active ingredient (%) 50
Solvent Triethylene glycol butyl e ther/xylene (1:3)
STORAGE and TRANSPORT
Please stir well before use, if the temperature is lower than 0℃, the oil may be layered or
muddy, heat to 30℃-40℃ and stir well.
Storage time is not recommended to exceed 12 months.
SPECIAL NOTES
Due to the high acid value of the product, it may catalyze the cross-linking of the baking paint
system. Viscosity rise during storage of the paint system should be checked.
APPLICATION GUIDELINES
Coating industry and printing inks
Properties and Advantages:
The additive unflocates and stabilizes the pigments by means of spatial site resistance.
the small size of the deflocculated pigment particles, multi-color pigmented systems are
prevented from color floating and blooming. This results in increased gloss, color strength,
transparency, and hiding power.
The additive reduces viscosity. The additive reduces viscosity, thus improving flow and
allowing for higher pigment additions. When used for electrostatic high speed spin coating of
inorganic pigments, it significantly reduces haze.
APPLICATION SECTORS
This additive is recommended for stabilizing inorganic pigments, especially titanium dioxide,
in solvent-borne and solvent-free coatings as well as in printing inks. Due to its anionic
character it is ideal for acid-catalyzed systems (e.g. coil coatings).
RECOMMENDED LEVELS
The amount of additive (in purchased form) is based on the pigment:
Titanium dioxide: 2%-4%
Inorganic pigments: 5%-10
The above data are empirical, the optimum dosage should be determined by a series of tests.
INCORPORATION AND PROCESSING INSTRUCTIONS
In order to obtain the best performance, the additives should be added to the abrasive before
the pigments.
