Recipe Suggestions

1. Add a rheology modifier (such as gas phase II) to the inorganic pigment paste Silicon oxide) has been shown to be beneficial

2. When producing carbon black slurry, a small amount of amine (0.2-3.0 %) is effective to neutralize partially acidic pigment surfaces

3. In case bubbles are generated during the pigment dispersion process, you can use high-efficiency but also Compatible defoamer concentrates such as (TEGO® Foamex 8050, TEGO® Foamex 810, TEGO® Foamex 830)

4. The starting formula for manufacturing color paste is available upon request.
