Polyphosphate solution

Typical Physicochemical Data

The data given in this data page are only typical values, not technical indicators of the product.

Acid value: 53 mg KOH/g

Density (20 ° C): 1.03 g/ml

Non volatile matter (10 minutes, 150 ° C): 52%

Solvent: propylene glycol methyl ether acetate/alkyl benzene 1/1

Flash point: 42 ° C

Storage and transportation

Mix well before use. Delamination or turbidity may occur, heat to 30-40 ° C and stir evenly.

Special attention

Due to the high acid value of the product, it may catalyze the crosslinking of the paint system. The viscosity rise of the paint system during storage shall be checked.

Application information

Paint industry and printing ink

Features and Benefits

The additive can deflocculate the pigment through space steric hindrance. Because the pigment particles of deflocculation are very small, high luster and color intensity can be obtained. In addition, transparency and hiding power are increased. The additive can reduce the viscosity, thereby improving the fluidity and increasing the amount of pigment added. When it is used for electrostatic high-speed rotary coating of inorganic pigment coatings, the fog shadow can be well reduced.

Recommended Applications

The additive is recommended to be used in solvent based and solvent-free coatings, as well as printing inks, to stabilize inorganic pigments, especially titanium dioxide. Because of its anionic properties, the additive is an ideal choice for acid catalytic systems (such as coil coatings).

Recommended dosage

Additive dosage (purchase form) is based on pigment

Inorganic pigment: 5-10%

Titanium dioxide: 2-4%

The above data are empirical dosage, and good dosage shall be determined through a series of tests.

Addition method and processing guidance

In order to obtain good performance, additives shall be added to the grinding material first, and then the pigment shall be added.
