Keeping color harmony was essential, but more importantly, the OEM needed to demonstrate antimicrobial effectiveness to validate performance claims. After developing a deep understanding of the customer’s needs, Avient’s team quickly went to work to formulate a custom OnColor™ color and then added Cesa™ WithStand™ antimicrobial technology to make a single Smartbatch™ masterbatch that passed all of the product’s challenging requirements.

CESA™ Slip Additives Lubrication PRODUCT SELECTION GUIDE Many polymer processing operations need lubrication to improve the process flow and/or part. They act as plasticizers to improve the flow of the polymer through the process (extrusion, injection molding, extrusion blow molding, etc), reducing the heat and energy needed.

Manufacturers save time and labor by eliminating the need for peel ply or other surface preparation such as grinding or abrading, while achieving superior adhesion compared to these typical processes. KEY CHARACTERISTICS • Improves bonding performance of epoxy adhesives in installation of pultruded parts • Eliminates need for surface preparation with abrasion or removal of peel ply layer prior to application of adhesives • Reduces overall system costs by saving time and labor on secondary processes • Enables replacement of mechanical fasteners with epoxy adhesives for improved fatigue performance and reduced weight • Simplifies manufacturing processes and reduces part complexity PRODUCT BULLETIN www.avient.com Copyright © 2020, Avient Corporation.
