Storage and transportation

Storage is recommended at 10-40℃, and be careful to avoid direct sunlight. The shelf life of the well-packaged products is 24 months from the date of production under suitable storage conditions.

Special attention

Avoid direct contact with the skin. If you contact your skin, rinse it with soap and with water.

Application message

Features and advantages:

Improve the wetting, shorten the grinding time and strongly reduce the viscosity; keep the pigment dispersed steadily and prevent flocculation, and increase the luster, color strength, transparency and covering force of the coating.

Application field

Automobile coatings, motorcycle coatings, etc., high polar resin industrial coatings, coil coatings.

Recommended dosage

Inorganic pigments 5-10% Organic pigments 10-30% Titanium dioxide 3-5% Carbon Black 60-120%

The above data are the empirical amount, and the optimal amount should be determined by a series of tests.

Add method guidance

To achieve the optimal performance, the resin and the solvent components were first premixed, slowly added with the additives and then evenly mixed, and then the pigment was added. If the order is wrong, it can be remedied by post-addition, but requires slowly added under high shear forces.
