This article, the third in a series, covers work done to improve the water resistance of water-based emulsions by replacing conventional emulsion surfactants with surfactants that will react into the polymer matrix.
What is the best respiratory mask to be used during powder coating application? The ChemQuest Group’s Joe Powder shares his powder coating knowledge and expertise by answering questions sent in from around the world.
PCI’s “Did You Know” column has published a wealth of information about redox chemistries for use in emulsion polymerizations. This edition focuses on its use in aqueous-based polymer dispersions.
Is moisture an important measurement in the manufacturing of powder coatings? What is the best way to degrease steel and aluminum prior to powder coating? Joe Powder, aka Kevin Biller of ChemQuest Powder Coating Research, shares his powder coating knowledge and expertise by answering questions like these sent in from around the world.
AkzoNobel offers insight on how businesses can reduce energy and further improve sustainability in their powder coating lines, from initial line loading and pretreatment, to application and curing.
We currently use a "midnight black” wrinkle powder coating supplied by a major powder producer. Can a second touchup coat be applied after the first coat has cured? Read the answer to this question and more in this edition of Ask Joe Powder.
A reader from Vietnam asks Joe if there is a way to reduce the hardness of powder coatings. She is using a polyester resin for a powder coating with a pencil hardness of 3H. However, her customer requires 1H hardness.
This article discusses how to control and quantify the amount of mixed polymer content as it can directly relate to the final morphology of the latex particles during polymerization.
