SMA resins have been effectively used as pigment dispersants and ink transfer aids for many years. This study quantitatively demonstrates that a new SMA copolymer derivative performed exceptionally well as a transfer aid.
This new neutralizing agent consists of up to 75% renewable raw materials, does not require labeling and is VOC/SVOC-free. This multifunctional additive improves the storage and freeze-thaw stability, reduces flash-rust discoloration and enhances the compatibility with pigments.
A simple rheological method based on a novel measuring system has been presented that enables the investigation in drying behavior of aqueous paints. The method has been successfully tested in the characterization in drying behavior of four commercial polymer dispersions and also in the investigation of the effect of two additives on the drying process of polymer dispersions.
This study has shown that DMMOPA has a unique combination of balanced physical properties. These physical properties offered DMMOPA-neutralized paints a multitude of performance advantages in a variety of waterborne paint systems as discussed in this article, such as enhanced hardness and solvent resistance in polyol-MF baking coatings, as well as better gloss, scrub resistance, water resistance and corrosion resistance in latex paints.
The results of this study can offer significant performance gains in formulating high-solids, high-build epoxy coatings. This is particularly important in regions where VOC emissions must be reduced significantly.
Functional coatings are an exciting and viable means to remove indoor air contaminants due to the significant surface area that walls, ceilings, doors and floors provide as a "vehicle" to degrade VOCs.
The introduction of new substrate wetting additives improves the spreading capacity of emulsion paints. Also the effectiveness in filling the crevices/pores of concrete substrates is highlighted by the results of accelerated efflorescence or alkali block testing.
The Lunda/Ames Joint Venture, a major partner in the multiyear construction of the St. Croix Crossing, chose to extensively apply an easy-to-use, low-toxicity corrosion inhibitor to protect various post-tension strands placed throughout the bridge during construction.
These micronized innovations are based on renewable raw materials in different particle size distributions that support customers’ ambitions to offer more sustainable solutions to industrial markets without compromising performance.
Our August issue has a big focus on equipment, with several articles and a directory of equipment suppliers. This issue also includes articles on transportation coatings, new binder technology and sustainability.
