Elastomeric roof coatings must show excellent adhesion to the substrate since they can be applied to several types of roofs such as metal, concrete, bitumen, and others. Fibrillated cellulose is a renewable material that delivers multiple functionalities such as rheology to stability and surface properties, as well as supporting a more sustainable lifecycle.

Primers are key to an effective coating system, and good primers serve several important functions including strong adhesion.

Plasma pre-treatment is a crucial step for improving the quality and durability of automotive assemblies and components. It enhances the adhesion and compatibility of different materials that are used for encapsulation, printing, or painting processes. By applying plasma to the surface of low-energy materials, it removes contaminants and creates functional groups that increase the surface energy and reactivity.

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.

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.
