TEGO DISPERS 750 W
TEGO DISPERS 750 W
TEGO Dispers 750 W is a slightly anionic, polymeric wetting and dispersing additive for high-quality waterborne formulations.
TEGO Dispers 750 W is very compatible.
TEGO Dispers 750 W is suitable for all kinds ofpigments.
With inorganic pigments, outstanding stabilization performance can be observed.
TEGO Dispers 750 W has low influence on coatings properties, therefore suitable for exterior applications.
TEGO Dispers 750 W is solvent-free.
TECHNICAL DATA about TEGO Dispers 750 W:
acid value (as supplied): Approx. 15 mg KOH/g
active matter content: approx. 40 %
appearance: yellowish clear liquid
chemical description: aqueous solution of a copolymer with groups ofhigh pigment affinity
pH-value approx.: 6.5

Aqueous solution of a copolymer with groups of high pigment affinity.
Used as a wetting and dispersing additive for waterborne formulations in pigment concentrates, flexo and gravure inks, inkjet inks, automotive and industrial coatings, leather coatings, wood and furniture coatings.
Offers very good color strength (development).
Possesses good storage stability of pigment concentrates.
Imparts water resistance.
Provides high color stability.
Is alkylphenolethoxylates (APEs) free.
Suitable for binder-free and binder-containing pigmented concentrates, and for inorganic and organic pigments.
Promotes pigment wetting and stabilization and thus prevents floating, flooding and settling of pigments.
Provides low viscosity and maximum color strength.

TEGO Dispers 750 W PROCESSING INSTRUCTIONS
Add to the grind before dispersion.
The product should notbe used as the only wetting and dispersing additive in a grind based on pigmentblack.
Before using uncoated stainless steel for storage and trasportof the product, the resistance should be checked.
TEGO Dispers 750 W HANDLING &STORAGE
When stored in an original unopened packaging between +4 and +40 °C, the product has a shelf life of at least 24 months from the date of manufacture.
TEGO Dispers wetting and dispersing additives promote pigment wetting and stabilization.
They prevent floating, flooding, and settling of pigments so that color coverage and intensity remain consistent during storage.
They ensure maximum color yield for the pigment, while also minimizing the number of milling steps.
Because these additives lower viscosity, coatings and pigment concentrates can be produced cost-effectively because pigment concentration can be maximized during dispersion.
For manufacturing waterborne pigment concentrates, we recommend TEGO Dispers 757 W, which is the preferred product for corrosion-resistant waterborne coatings.
Much like TEGO Dispers 750 W and TEGO Dispers 755 W, TEGO Dispers 757 W satisfies high demands in regards to optical properties.
The TEGO Dispers 65x series’ technology is currently the market standard for alkylphenolethoxylate-free universal pastes for waterborne and solventborne formulations.
Modern solventborne formulations may be developed particularly well with TEGO Dispers 656, 670, and 685.
For UV systems, we recommend TEGO Dispers 685 for all pigment types and TEGO Dispers 688 for matting agents.
All TEGO Dispers products are alkylphenolethoxylate-free.
Numerous TEGO additives and specialty resins are available to tailor the functionalities of coatings to suit a broad range of applications.
Thus, our customers can differentiate themselves from their competitors by offering innovative coatings.
For example, floor coatings can be made electrically conductive using anti-static additives.
Silica nanocomposites are particularly effective in making high-gloss coatings for wood and plastics resistant to scratch and abrasion.
At the same time, such products improve barrier effects against water vapor, gases, and solvents.
Surface properties may be manipulated for “easy-to-clean” characteristics.
Architectural paints may be formulated with water repellency properties that increase the longevity of buildings.
Release properties lead to blocking resistance, which ensures that two coated surfaces (such as window frames) do not stick together.
