The data given on this data sheet are typical values and are not technical specifications of the product.
Appearance Colorless to light yellow liquid
Density g/cm³ (23°C): 1.00-1.20
Acid value (mg KOH/g): 90-180
Viscosity cps (25℃): 300-3000
Active ingredient (%): 100
STORAGE and TRANSPORT
Please stir well before use, delamination or turbidity may occur when the temperature is lower than 0℃, heat to 30℃-40℃ and stir well.
Storage time is not recommended to exceed 12 months.
SPECIAL NOTES
The high acid value of the product may catalyze the cross-linking of the baking paint system. Viscosity rise during storage of the paint system should be checked.
APPLICATION GUIDELINES
Properties and Advantages.
This additive unflocates and stabilizes pigments through spatial resistance. Due to the small size of the deflocculated pigment particles, multi-color pigmented systems do not produce color float or bloom. This increases the gloss, color strength, transparency and hiding power of the coating. The additive reduces viscosity, thus improving flow and increasing the amount of pigment added. 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 and the optimum dosage should be determined through 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.
