Formulators and manufacturers around the world rely on 3M paint additive technologies to help enhance performance, reduce costs and add more customer-pleasing properties to a broad range of architectural and industrial paints and coatings.
Paint Additive Technologies to Enhance Performance and Reduce Costs
Evaluating Fluoropolymer-Based Stain-Resistant Additives and Sealers
By Wayne Fan, Ph.D.,
There is growing recognition that improving a product’s resistance to staining and soiling can greatly enhance its appeal, both to consumers and to commercial users. This applies to a wide variety of hard surfaces including porous stone, concrete and tile, as well as construction materials such as paints, caulks and grout. Whether the application is a backyard patio or a bustling auto repair garage, end users require effective, durable treatments that will stand up to long-term use, repeated cleaning and, in many cases, exposure to the elements.
Expanding the Use of Spherical Fillers in Low-VOC Coatings Applications
The uses and advantages that ceramic microspheres offer architectural coatings applications are well documented and constantly expanding with the introduction of new additives and binder technologies. These spherical, hard particles offer formulators opportunities to lower binder demand and control viscosity and VOCs while increasing burnish and scrub resistance. The industrial coatings market is another large market segment that is being driven toward zero-VOC coatings with improved performance properties. This application study involves the evaluation of spherical ceramic microspheres and hollow glass bubbles versus other conventional fillers in a high-solids, two-part epoxy coating.
Functional Fillers for Matting and Performance Enhancements in Waterborne, UV-Curable Coatings
In Part 1 of this series, ceramic microspheres and glass bubbles were evaluated in a high-solids, two-part epoxy coating for industrial applications and other end uses such as concrete floor coatings. Benefits included higher volume loadings and lower VOCs at lower viscosities, in addition to better film integrity, as manifested by improved abrasion resistance. Part 2 of this series evaluates the same ceramic microspheres, silica matting agents and nepheline syenite in a waterborne, UV-curable polyurethane dispersion. Conventional silica matting agents are commonly used for these coatings. Ceramic microspheres and nepheline syenite are crystalline silica-free pigments. Properties such as matting efficiency, scratch resistance and viscosity control were studied in addition to the effect each material had on clarity and haze. All of these properties are important in obtaining a final finish that is both decorative and functional.
3M™ Fluorosurfactants are a family of advanced wetting and leveling agents, used to improve performance in a broad range of aqueous and solvent-borne coatings, including paints, resins, adhesives, inks, clearcoats, floor coverings and more. These non-ionic polymeric fluorosurfactants offer unmatched control of surface defects such as orange peel, cratering, fish eyes and picture framing, while providing improved performance on hard-to-wet surfaces such as plastics and oily metals.
What's more, 3M fluorosurfactants help to maintain low surface tension throughout the entire drying process. This helps to create smoother, higher gloss coatings.
