Application field
paint industry
Features and Benefits: This additive is used to produce high-concentration matting pastes. This kind of slurry is liquid, stable in storage, easy to use, suitable for automatic metering system, and can also be added at the end to adjust the degree of extinction. The matting effect of matting paste produced with DISPERBYK-103 may be slightly lower than that of matting agent in dry powder form.
Recommended use
| Wood and Furniture Coatings | Specially Recommended |
| Industrial Coatings | Specially Recommended |
| Anti-corrosion coating | recommended |
| Architectural Coatings | recommended |
Recommended dosage
Auxiliary dosage (as purchased) based on pigment:
| Inorganic Pigment | 5-10 % |
| Titanium dioxide | 2-4 % |
| Matting powder | 30-60 % |
The above recommended dosage is for reference, and the optimum dosage needs to be determined through a series of tests.
Joining method and processing guidance
For optimum performance, additives should be added to the millbase. When producing matting paste, first mix the paste resin with solvent and auxiliary, and then put in matting powder. For example: grinding resin (60% solution), 30 parts; DISPERBYK-103, 12 parts; solvent, 40 parts; matting powder, 18 parts.
