How Dispersants Influence Sprayability in Refinish Applications

2026-02-04

Dispersants Impact More Than Pigment Stability

The effectiveness of a dispersant influences not only pigment stability but also the rheology of the coating under shear. This directly affects how the material flows through spray equipment. Inconsistent dispersion can result in nozzle clogging, uneven atomization, and variable film thickness in refinish applications.

Visible Defects in Applied Coatings

Poor dispersion often manifests as orange peel, streaking, or mottling in the final film. These issues are particularly pronounced in metallic and pearlescent finishes, where uneven pigment distribution can alter color perception and visual depth.

Compatibility and Selection Are Key

Selecting dispersants that are compatible with both the pigment and resin system is critical. Effective dispersants provide rapid pigment wetting, long-term stabilization of high-strength or effect pigments, and maintain the desired rheology, ensuring smooth sprayability and consistent film build.

From Lab to the Body Shop

When dispersants perform as intended, coatings flow smoothly through spray equipment, atomize evenly, and form uniform films without defects. This reduces rework, minimizes material waste, and ensures consistent appearance and color accuracy.

Ensuring Predictable, High-Quality Results

In automotive refinish coatings, effective dispersants bridge the gap between formulation and application, transforming lab-tested pigment stability into reliable spray performance. The result is smoother application, uniform film build, and reduced operational risk.
