By definition, additives are added in small quantities, often less than one point percent, to re-inforce selected chemical or physical properties of the finished paint. The powder coatings sector is no exception, and has some limitations that are intrinsic to the technology itself, which are linked to the physical state of the paint before application on the piece to be painted.
Organic polymethyl urea matting agents impact the aesthetic appearance of a coating made with a metallic pigment in two ways: it reduces the flop index and increases the "sparkle" effect.
Evonik’s Coating Additives business offers a diverse portfolio of products including additives, co-binders, matting agents, rheology modifiers, specialty resins and nanoresins. Brands include ACEMATT®, AEROSIL®, SURFYNOL® and TEGO®.
These post-addable additives can be effectively utilized as post-addible solutions to alter smooth or glossy stocked powder coatings into matted or textured finishes while circumventing the high research and development, and production costs normally associated with small, quick turnaround orders and reducing manufacturing complexities.
W. R. Grace & Co., Columbia, Maryland, has received Sherwin-Williams' Certified Supplier Award for achieving the highest level of product quality, performance and outstanding customer service.
Additives based on hyper-branched polymers with tailor- made particle-affinic groups lead to very high-performing products to be used in silica matted solvent-free UV-curing coatings.
According to a new study released by Research and Markets, the global matting agents market is witnessing growth due to increasing applications, technological advancements, and increased demand in the Asia-Pacific region, mainly from Southeast Asia, China and India.
The alternative matting agents discussed in this article offer a first step to developing new ways of controlling the light scattering properties of radiation-curable coatings.
