As the coatings industry continues to prioritize waterborne systems, further research to provide coatings with comparable properties to those based on solvent-based systems is required. This paper, winner of the PCI Award for Technical Excellence at the 2023 Waterborne Symposium, presents a surfactant-free encapsulation process that enables the enclosure of polysiloxanes of arbitrary molecular weight in capsules of nanometer size in a simple, scalable process.
This month’s Formulating with Mike column is the conclusion to a three-part series, and covers the emulsification process as well as test data of alkyd emulsions.
The new resins have a renewable carbon content, can be formulated and used without hazardous ingredients found in most competitive products, and were developed to have efficient crosslinking with environmentally compliant carbodiimide-type crosslinkers.
The technologies discussed in this article promote significant efficiency gains, production time and cost reductions, agglomerate prevention, more efficient raw material utilization additive savings, biocide reduction, and simplified cleaning, among other benefits.
Learn how the amount of actual dispersant added on pigment solids will have an effect on tinting power, stability, compatibility of formulations, and other properties.
Penn Color Inc. will launch a portfolio of high-performance dispersions at the European Coatings Show 2023 (ECS) in Nuremberg, Germany, being held March 28-30, 2023.
