Storage and Shipping
Mix well before use. Separation or turbidity may occur during storage and transport, heat to 30-60 °C and mix well.
special Reminder
When using white baking paint, first test whether DISPERBYK-2150 will cause yellowing Change. In case of yellowing, DISPERBYK-180 is recommended to stabilize the titanium dioxide.

paint Industry
Product characteristics and advantages: The additive stabilizes the pigment through steric hindrance Deflocculation, which also charges the pigment particles with the same nature. The resulting repulsion effect and steric stabilization prevent the pigment from coarsening, thereby eliminating the problem of color floating and blooming in systems containing multiple pigments. Due to the small particle size of deflocculated pigments, high gloss can be obtained and color strength can be improved. In addition, the transparency of transparent pigments and the hiding power of opaque pigments can be improved. due toThe degree of pressure is reduced, the leveling performance is improved, and the amount of pigment added can be increased.
Recommended Purpose
DISPERBYK-2150 has excellent compatibility with all conventional solvent-borne paint binders In particular, it also has good compatibility with thermoplastic acrylic (TPA) and nitrocellulose systems. The additive is especially recommended for the production of resin-containing pigment concentrates. Since it reduces the viscosity of the millbase significantly, it can increase the pigment content of the color paste. The additive can also be used for co-grinding of pigments in solvent-borne coatings.
Suggestions Dosage
Adjuvant dosage (purchase form) is based on:
| Inorganic pigment | 10-15% |
| titanium dioxide | 3-5% |
| Organic Pigments | 30-60% |
| Carbon black | 60-140% |
The above recommended dosage is for reference, the optimal dosage needs to be determined through a series of experiments .
Join Methods and processing instructions
In order to obtain the best performance, the additive must be added to the grinding base first, and then Throw in paint. Pre-mix the resin and solvent components in the mill base, and then add the additives slowly while stirring. Pigments should only be added after the additive has been dispersed evenly.
