PTFE is a substance used in all types of coatings to modify total mechanical performance and improve values for scratch resistance and abrasion resistance, while simultaneously lowering surface friction. However, PTFE is a well-known representative of PFAS, which is under increasing global regulation. PTFE-free wax additives are now available, and provide comparable performance with a focus on improving abrasion and scratch resistance.
The production of effective, functional, and hygienic medical devices can be aided by the use and advancement of surface coatings that can alter physiochemical properties and functionality, among other features.
Concerning rheological stabilization of coatings, there is a trend to move away from hazardous raw materials, with preference given to the use of bio-based and sustainable chemistries, wherever possible. Testing of new organic additives shows good dispensability and ease of activation.
Abrasion is one of the most important defects that deteriorates the durability of coatings. The goal of the research presented in this article was to achieve a good understanding of the effects of coating additives on the abrasion resistance of waterborne coatings.
Semibatch emulsion polymerizations are predominately run in “starve-fed” mode, but what does that really mean? In this edition of PCI’s Did You Know column, EPCEd discusses the reasons to run in starve-fed mode, and more.
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.
In an industrial technical coatings environment, continuous-loop and start-stop paint lines have proven to be highly beneficial in terms of efficiency and productivity, and when combined with the expertise of a third-party technical coatings provider, manufacturers can optimize their production processes and improve the quality of their finished products.
While recent years have witnessed a bit of a slowdown in the growth of the automotive sector, the value produced by body shops and repair facilities has increased significantly, which illustrates the market for automotive refinish coatings' potential for expansion.
Color collateral has always been designed with consumers in mind. Past market needs continue to drive innovation toward accurate and easy-to-use collateral products. A new approach to color sampling for transparent and semi-transparent stain applications is discussed in this article.
