Furthermore, its good wetting and dispersibility properties allow particles to spread better on the surface and maintain film integrity. Its compatibility optimizes interaction with resins and additives, while its processing advantages simplify production processes and reduce energy consumption. This allows Add Dispers RC 40A to achieve high-performance paint films in environmentally friendly systems.Dispersion Agent Characterization Techniques: FTIR AnalysisThe chemical structure of polyacrylic acid was investigated by FTIR spectroscopy (Figure 3). In the obtained FT-IR spectra, the characteristic absorption bands at wavenumber 1651 cm%u22121, which are specific to carboxylic acid salts, correspond to C-OH deformation vibrations, while two bands at wavenumbers 1559 cm%u22121 and 1324 cm%u22121 (symmetric stretching vibrations of carboxylic anions -COO%u2212) appear. 30 TURKCOAT Aral%u0131k / December - Ocak / January 2026%u015eekil 3: Poliakrilik asit sentez %u00fcr%u00fcn%u00fcn%u00fcn IR AnaliziFigure 3: IR Analysis of polyacrylic acid synthesis productDispersiyon Ajan%u0131 Karakterizasyon Teknikleri: GPC Analizi ve Molek%u00fcl A%u011f%u0131rl%u0131%u011f%u0131n%u0131n Boya %u00dczerine EtkisiPolimerik olan dispersiyon ajanlar%u0131 aras%u0131nda poliakrilat, polyester, polieter veya poli%u00fcretan bazl%u0131 sistemler bulunur.

Classification of polymeric dispersing agents is based on chemical structure (polyacrylic, polyurethane, copolymer, etc.) and molecular weight. Dispersing agents with molecular weights of approximately 5.000-30.000 g/mol are the most commonly used in industrial paints. Products with these molecular weights provide superior performance to the paint, including excellent wetting power, reduced dispersion time, long-term stabilization, and steric hindrance.
