    Study Notes

    Specialty Monomers and Emulsifiers

    • Sipomer® PAM-4000, Sipomer® WAM/WAM II, and Sipomer® COPS series are effective specialty monomers for enhancing wet adhesion and stability in coatings.
    • Effective wet adhesion monomer suitable for wood, aged alkyd, and leather substrates is Sipomer® WAM.
    • Sipomer® COPS-3 provides enhanced scrub resistance in high PVC paints for improved durability.

    Emulsifiers for Latex Polymer Manufacturing

    • Solvay Novecare supplies a variety of emulsifiers for Vinyl Acrylic, VEOVA, and VAE polymers.
    • Phosphate ester anionic emulsifiers improve film properties; nonionic surfactants ensure latex stability.
    • Electrostatic stabilization is provided by anionic surfactants, beneficial in low to moderate salt concentrations.

    Water Resistance and Anti-Corrosion Improvements

    • Rhodafac® RS 610E and RS 710E are excellent primary emulsifiers improving overall latex performance in coatings.
    • Achieve better water resistance, adhesion, and corrosion protection with Rhodafac® products.
    • Water adsorption can be reduced in clear coats, enhancing durability and longevity.

    Water Resistance Testing

    • Comparison of polymer films made with different emulsifiers demonstrates that Rhodafac® significantly improves water resistance after immersion tests.
    • Films formulated with Rhodafac® maintain integrity even after prolonged water exposure.

    Functionality of Aerosol® Emulsifiers

    • Aerosol® EF-800 is highly effective as a sole emulsifier and shows good performance in high solid content formulations.
    • Suitable for various systems like Vinyl Acrylics and Styrene Butadiene; operates effectively at low concentrations (0.5 - 2%).

    Properties of Rhodapex® and Rhodacal® Products

    • Rhodapex® AB/20M and Rhodapex® BSA offer stability and particle size control, including enhanced water resistance and gloss properties.
    • Rhodafac® RS series emulsifiers are APE-free and enhance color acceptance and block resistance.

    Pressure Sensitive Adhesives (PSA) Emulsions

    • Solvay’s offerings for PSA emulsions include APE and VOC-free emulsifiers.
    • Sipomer B-CEA provides excellent adhesion and flexibility, and is effective in increasing filler loading capacity.
    • Aerosol® A-196 variants act as versatile emulsifiers, assisting in the formulation of regulatory-compliant latexes.

    Additional Benefits of Emulsifiers

    • Many emulsifiers in this range function effectively at low concentrations, enhancing the formulation and reducing costs.
    • Stability during polymerization processes is improved, minimizing final product flaws such as grit and coagulum, leading to higher yield and quality of latex.
