Waterborne latexes are produced via emulsion polymerization, in which surfactants or emulsifiers are the key components to control latex properties. Much effort has been made to reduce the impact of surfactants on the performance of waterborne formulations. One of the promising approaches is to use polymerizable or reactive surfactants to prepare latex polymers.
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 columncontinues the focus on resins and discusses acrylic emulsion polymerization, in particular, surfactant design and how it affects the polymerization of a vinyl-acrylic emulsion.
Microfibrillated cellulose (MFC), a bio-based and multi-functional product made of cellulose, is a new alternative to traditional thickeners. Learn how MFC increases the tensile strength of elastomeric acrylic roof coatings without sacrificing the elongation, and how it reduces the water absorption, as well as increases the adhesion of coatings.
The publication of "Innovability 2022: IOD Pathway to the Future" presents the progress of the company's sustainability strategy and reaffirms Its commitment to the UN's 2030 agenda.
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.
Brenntag and Kao have a long-standing successful partnership in Sweden and Norway, and will now serve customers in the entire Nordic region with a portfolio of surfactant solutions.
Sustainability dominated every conversation at the 2023 European Coatings Show. Learn about some of the innovative technologies that were introduced to help the industry formulate, manufacture, and apply the coatings of tomorrow.
Increased regulatory pressure around the use of fluorosurfactants has led to a search for alternative surfactants that still provide good wetting and leveling attributes.
