Introduction

In the paint, coatings, printing inks, and pigment paste industries, choosing the right dispersing agent directly impacts the final product quality. Proper pigment dispersion increases gloss, improves color strength, reduces mill-base viscosity, and prevents flocculation, flooding, and floating.

ADDEX-DS 1047, developed by Noyan Afzon Chem, is a solvent-based wetting and dispersing additive designed for coating systems, pigment pastes, and printing inks. In terms of performance, it can be evaluated as a functional alternative to DISPERBYK-163 in many formulations.

In this article, we compare the technical specifications of these two products side-by-side to make the selection and evaluation process easier for formulators.

What is ADDEX-DS 1047?

ADDEX-DS 1047 is a solvent-based wetting and dispersing agent formulated based on modified polyurethane, designed for the stable dispersion of inorganic, organic, and carbon black pigments in high-gloss systems. By reducing viscosity, increasing color strength, and improving stability, this product helps formulators enhance the final coating quality.

Key benefits of ADDEX-DS 1047

• Mill-base viscosity reduction
• Gloss enhancement
• Grinding time reduction
• Prevention of pigment separation (flooding and floating issues)
• Compatibility with a wide range of resins

What is DISPERBYK-163?

DISPERBYK-163 is a wetting and dispersing additive for solvent-based systems and pigment pastes, widely used to stabilize pigments in industrial formulations. It is also based on modified polyurethane and is recommended for organic, inorganic, TiO2, and carbon black pigments.

Key benefits of DISPERBYK-163

• Improved color strength
• Increased transparency and gloss
• Viscosity reduction
• Prevention of flocculation
• Pigment stabilization in solvent-based systems

Technical Discussion

Both products belong to the same application class:
“Wetting and dispersing agents for solvent-based systems”.

The only observed difference between these two products is approximately a 5% variance in their solid content. This difference stems from variations in formulation, the proprietary technical knowledge of the two companies, and the chemical structure and molecular weight of the active ingredient.

From a formulator’s perspective, this means ADDEX-DS 1047 can serve as a highly suitable functional alternative for many solvent-based formulations, especially when the goals are cost optimization, local sourcing, and reducing reliance on imports.

Recommended Applications of ADDEX-DS 1047

This product is suitable for the following applications:

• Industrial coatings (coil coatings, can coatings, epoxy, Polyurethane)
• Automotive coatings (OEM, refinish)
• Printing inks (nitrocellulose and Polyurethane)
• Pigment pastes / color concentrates

Advantages of Using ADDEX-DS 1047

• Shorter grinding and production time
• Improved pigment wetting and dispersion
• Viscosity reduction during grinding (mill-base) and in the final product
• Enhanced coating gloss
• Improved stability during storage shelf-life
• Compatibility with a wide range of resins (alkyd, acrylic, Polyurethane, epoxy, polyester, nitrocellulose)
• Highly suitable functional alternative in many formulations

Who is ADDEX-DS 1047 compared to DISPERBYK-163 designed for?

If you are:

• An industrial paint manufacturer
• An automotive coatings manufacturer
• A printing ink formulator
• Working on pigment pastes and color concentrates
• Looking for a local alternative to foreign grades
• Seeking to lower your finished product costs

ADDEX-DS 1047 is an excellent option for testing and evaluation in your production line.

Customer Feedback and User Experience

Feedback from the Research & Development (R&D) and Quality Control (QC) departments of various coating manufacturers demonstrates that ADDEX-DS 1047 delivers value far beyond that of a mere cost-effective alternative. Many formulators have reported that this dispersing agent not only competes directly with its foreign counterpart (DISPERBYK-163) in key performance indicators—such as mill-base viscosity reduction, color strength, and the prevention of flooding and floating—but also exhibits superior compatibility in certain systems. Consequently, it minimizes the risk of unwanted phenomena such as film turbidity or phase separation.
