TEGO Dispers 700 — Technical Profile
TEGO Dispers 700 is a Polymeric-based wetting and dispersing additive manufactured by Evonik Industries AG (Germany), part of the TEGO Dispers product line.
How It Works
TEGO Dispers 700 adsorbs onto pigment surfaces via anchoring groups (amine, acid, or polar functionalities), then stabilizes the dispersion through steric and/or electrosteric repulsion of the polymeric tails. This prevents flocculation, reduces grinding time, improves color strength, and prevents flooding/floating in multi-pigment systems.
Key Specifications
| Property | Value |

| Recommended dosage | 5–40% based on pigment weight (inorganic); 15–70% based on pigment weight (organic) |
Applications
- Coatings
- Inks
Dosage & Addition
- Recommended dosage: 5–40% based on pigment weight (inorganic); 15–70% based on pigment weight (organic)
- Addition point: Add to the millbase before pigment addition; must be present during grinding
Formulation Considerations
W-suffix grades (740 W, 747 W, 750 W, 755 W) are waterborne-specific. Non-W grades (630, 670, 685, 695) are solventborne. Grade 656 is universal (WB + SB). Proper dosage optimization via rub-out test is essential.
Looking for a TEGO Dispers 700 Alternative?
Our SEMITECH Additives range offers functionally equivalent wetting and dispersing additives that deliver the same performance as TEGO Dispers 700 — matched surface tension reduction, compatibility profile, and application behavior — at 20–40% lower cost.
Why formulators switch to SEMITECH Additives:
- Drop-in replacement — no reformulation needed in most systems; matched chemistry (Polymeric) ensures equivalent performance at the same dosage (5–40% based on pigment weight (inorganic); 15–70% based on pigment weight (organic))
- Competitive pricing — 20–40% cost advantage vs. Evonik list price, with volume tier discounts available
- Reliable supply — direct from manufacturer in China, 2–4 week lead time, safety stock programs available
