Use Description

Add grinding before dispersion

This product should not be used as the only wetting and dispersing agent when grinding carbon black pigments Additives

Resistance testing should be conducted before using uncoated stainless steel for storage and transportation products

Recipe Suggestions

1. Very good viscosity reducing substitute: TEGO® Dispers 755 W

2. In order to achieve the best blackness of lamp black, use TEGO® Dispers 750 W is effective with TEGO® Dispers 760 W (4:1 to 1:1 active).

3. In case bubbles are generated during the pigment dispersion process, you can use high-efficiency but also Compatible defoaming

Agent concentrate (such as TEGO® Foamex 8050, TEGO® Foamex 810, TEGO® Foamex 830).

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

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