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.
This article details a statistical design experiment that was commissioned to explore in more detail the roles and effectiveness of varying parameters (raw materials, PVC, types of steel, etc.) in producing intumescent paints.
The January issue features spectroscopic analysis of architectural coatings for improved weathering, a new generation of REACH-compliant ketamine epoxy curing agents, a look at what drives color forecasting, a study of icephobic coatings, and more.
