Despite steady progress, there is still need for improvements. Recent innovations in the area of polymer colloids and hybrid materials offer new opportunities to develop novel coatings for metal protection.
By choosing the appropriate technology, it is possible to design acrylic binders with improved barrier properties, low water uptake, and improved anticorrosion properties. Different methodologies will be discussed, including: designed particle morphology, engineering of the water phase composition, and the use of hybrid binders. Also, a new technology exceeding basic barrier function will be presented. This utilizes a built-in, enhanced corrosion protection mechanism resulting in outstanding performance in salt-spray and early rain resistance.Note de contenu : - Water-based acrylic dispersions : high performance and environmentally friendly.
- Key factors affecting film formation, barrier properties, and anticorrosion performance.
- New approaches to high-performance waterborne acrylic dispersions.
- Designed particle morphology for improved anticorrosion performance.
- Barrier and inhibiting waterborne dispersions
- Dispersions designed for DTM via superior film formation and minimization of water-soluble components.

ThermogravimétrieIndex. décimale : 667.9 Revêtements et enduits Résumé : Traditional waterborne polyurethane (WPU) has poor water resistance because of the incorporation of permanent hydrophilic groups, such as carboxyl group or ammonium salt, into polymer chains. Therefore, developing WPU with excellent water resistance and mechanical properties is highly desirable for industrial applications. In this study, CO2-triggered hydrophobic/hydrophilic switchable waterborne polyurethane–acrylate (WPUA) containing methyl methacrylate (MMA) units were designed and synthesized. The molecular structure, hydrophobic/hydrophilic switchable behavior, water resistance, and mechanical properties were systematically investigated and characterized. The WPUA with 10 wt% MMA exhibited a low water uptake (2.15 wt%) and linear swelling ratio (0.17 L%), as well as a high tensile strength (16.7 MPa) and modulus (85.9 MPa), which were much higher than those of the pristine WPU. This study indicated that the CO2-triggered WPUA dispersed stably as latex particles in water and possessed excellent water resistance and mechanical properties after the film formation.

Stabilité thermiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Waterborne hyperbranched alkyd–acrylic resins (HAAR) are interesting materials that provide excellent properties yet require only low levels of solvent in formulations using them. However, they have been scarcely studied. Therefore, the goal of this work was to prepare and evaluate various properties of HAAR. These materials were obtained by miniemulsion polymerization from a hyperbranched alkyd resin (HAR), methyl methacrylate (MMA), butyl acrylate (BA), and acrylic acid (AA). The proportions of HAR:acrylic monomers were as follow: 50:50 (HAAR1), 40:60 (HAAR2), 30:70 (HAAR3), and 20:80 (HAAR4). The particle size increased with the content of HAR, but the colloidal stability, critical deformation, zeta potential, thermal stability, and hardness followed an opposite behavior. The order of colloidal stability of the HAAR miniemulsions was HAAR4 > HAAR3 > HAAR2 > HAAR1. The particle morphology of the HAAR was mainly core–shell, but acrylic and alkyd particles were also observed. In addition, all HAAR initially exhibited a reduction in complex viscosity (η*) with the increase in angular frequency. The thermal stability of the HAR was lower than that of the HAAR. The HAAR showed better resistance against a 0.10 M sodium hydroxide (NaOH) solution than HAR. Note de contenu : - EXPERIMENTAL : Materials - Synthesis of the HAAR - Characterization
