BYK DISPERBYK 162 wetting and dispersing additive for solvent-borne coatings and pigment concentrates

DISPERBYK -162

Wetting and dispersing additive for solvent-borne coatings and pigment concentrates. Especially suitable for stabilizing carbon black and organic pigments, especially two-component polyurethane wood and furniture coatings.

Chemistry Composition

High molecular weight block copolymer solution containing pigment affinity groups

Typical Materialized data

The data given on this data page are only typical values, not the technical indicators of the product.

special Note

Surface treatment of certain organic pigments can affect the effectiveness of the wetting and dispersing agent adverse effects. In this case, untreated pigments of the same type can be tried. When used in coil coatings, the interaction between the cationic additive and the acid catalyst must be considered. Free acids or epoxy-blocked acids are more suitable than amine-blocked acids. This problem can be avoided by using the DISPERBYK-170 series.

Apply Information

paint Industry

Features and advantages: This high molecular weight additive deflocculates pigments through steric hindrance and stable. DISPERBYK-162 imparts an equal charge to the pigment particles. The resulting repulsive force and steric stabilization can effectively avoid possible co-flocculation, so that the multi-pigment system will not produce color floating and blooming. The additive's deflocculating properties increase the gloss, color strength, clarity and hiding power of coatings while reducing the viscosity of the millbase.

Recommended Apply

This additive is mainly used in wood coatings and pigment concentrates.

Recommended Dosage

Auxiliary dosage (purchase form) based on pigment:

The above data is the empirical dosage, and the optimal dosage needs to be determined through a series of experiments.

join Methods and Processing Guidelines

In order to obtain the best performance, the additive should be added to the grinding base first, and then Add paint. The resin and solvent components of the millbase are premixed first, then the additives are added slowly with constant stirring. Do not add pigments before the additives are mixed evenly.
