BYK-9077

Coatings, printing inks, adhesives and PVC plastisols
Special Features and Benefits
BYK-9077 deflocculates pigments by means of steric stabilization. It also generates a uniform electrical charge in the pigment particles. The resulting repulsion effect and the steric stabilization prevent any coflocculation which leads to non-floating coloring in pigment blends. As a result of the small particle size of the deflocculated pigments, high levels of gloss can be achieved and the color strength is improved. In addition, the transparency is increased in transparent pigments and the hiding power in opaque pigments. The viscosity is reduced. In this way, the flow characteristics are also improved and a higher pigment load is possible.
Recommended Use
BYK-9077 is suitable for all pigments and is particularly recommended for stabilizing basic carbon black pigments. It is used in solvent-borne and solvent-free coatings, adhesives and PVC plastisols as well as in solvent-free UV printing inks. A key application area is solvent-free pigment concentrates for these applications.
Recommended Levels
Amount of additive (as supplied) based upon pigment:

• Inorganic pigments: 5-10%
• Titanium dioxides: 1-3%
• Organic pigments: 10-25%
• Carbon blacks: 15-50%

The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.

Incorporation and Processing Instructions

For optimum performance, the additive must be incorporated into the millbase before addition of pigments.

SMC and pultrusion
Special Features and Benefits
BYK-9077 is recommended for stabilizing organic pigments and particularly basic carbon blacks.
Recommended Levels
5-30% additive (as supplied) based on organic pigments and carbon blacks for pigment stabilization. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions

For optimum performance, the additive should be added to the resin mixture before homogenization and before the addition of solids.

Recommended Use
BYK-9077 is suitable for all pigments and is particularly recommended for stabilizing basic carbon black pigments. It can also be used to improve the wetting of carbon fibers. This brings about a greater process reliability.
Recommended Levels

• 5-30 % additive (as supplied) based on organic pigments and carbon blacks for pigment stabilization.
• 0.5-1 % additive (as supplied) based on the fiber content, for wetting carbon fibers.

Thermoplastics
Special Features and Benefits
BYK-9077 significantly reduces the viscosity and brings about Newtonian flow characteristics in the millbase. It improves the torque build-up, the throughput, the viscosity (MVR), the filter pressure value (FPV), and the dispersion quality.
Recommended Use
BYK-9077 is recommended for organic pigments and particularly for basic carbon black pigments. It is used in thermoplastic compounds and color masterbatches based on PE, PP, ABS, PVC, PET and PA.
Recommended Levels
5-30% additive (as supplied) based on organic pigments and carbon blacks for pigment stabilization. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions

For optimum performance, the additive should be added to the pigments or the plastic prior to, or during compounding.

BYK-9077 does not contain plasticizers.

High molecular-weight copolymer with pigment affinic groups

Separation or turbidity may occur at temperatures below 10°C. Warm to 60°C and mix well. Product efficiency is not influenced.
