SURFADIOLS 110
Wetting and Dispersing Additive
SURFADIOLS 110
(Alternative to Disperbyk-110)
SURFADIOLS 110 is a wetting and dispersing additive for solvent-borne systems. It is composed of a solution of a copolymer with acidic groups. This product is suitable for stabilizing inorganic pigments, especially titanium dioxide, and strongly reduces millbase viscosity.
The additive deflocculates pigments by means of steric stabilization. As a result of the small particle sizes of the deflocculated pigments, high levels of gloss can be achieved and the color strength is improved. Transparency and hiding power also increase and viscosity is reduced. In this way, the flow characteristics are also improved and higher pigment loading is possible. For inorganic pigmented coatings, which are applied using electrostatic high rotation equipment, haze is significantly reduced.

Special properties
Scope of application
The additive is recommended for all solvent-borne coatings and printing inks to stabilize inorganic pigments, specifically titanium dioxide.
Incorporation and Processing Instructions
For optimum performance, the additive must be incorporated into the millbase before addition of pigments. Mix well before use.
Recommended Levels
Amount of additive (as supplied) based upon pigment:
Inorganic pigments: 5% – 10%
Titanium dioxides: 2% – 4%
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Package and storage
The standard package is 25kg or 200kg plastic/iron drums.
As a result of its high acid value, the additive may potentially accelerate the reaction of baking systems. Check the increase in viscosity during storage.
Keep containers tightly closed in a dry, cool, and well-ventilated place. Separation and turbidity may occur. Heat to 30-40°C and stir.
When stored in an original unopened packaging, the product has a shelf life of 24 months from the date of manufacture.
