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.
