FIBER-LINE™ PERFORMANCE ENHANCING COATINGS PRODUCT SELECTION GUIDE FIBER-LINE™ COATING SELECTION GUIDE COATING Bondcoat™ Adhesion Enhancing Colorcoat™ Fiber Color Packcoat™ Performance Enhancing Protexcoat™ UV Resistant Swellcoat™ Blocker Water Blocking Swellcoat™ Water Absorbing Wearcoat™ High Abrasion Blockcoat™ Anti-Wicking Repelcoat™ Water Repellant Flamecoat™ Flame Resistant FEATURES • Created for applications where an untreated fiber does not have the ability to provide the appropriate amount of bonding characteristics to another material • Provides adhesion to another fiber or substrate without impacting other performance properties • Improves adhesion of the fiber to the resin matrix it is introduced into • Enables industry standard “burst” tests or stringent delamination analysis • Designed to achieve vibrant colors for safety, identification, and aesthetics • Specialized formulas and binders adhere the pigment to the exterior of the individual filaments, while impregnating deep into the fiber bundle • Available by Pantone or RAL number • Compatible with a variety of composite resins including epoxy, polyurethane, and polyethylene • Stronger than solution-dyed fibers • Designed to add lubricity and temperature resistance at the filament level for braided compression packing • Coating at the fiber level versus the finished braid achieves higher % level coating • Fiber level coating extends the life of the braid and reduces required maintenance • Various formulations available • PTFE, silicone, graphite, and mineral oil • Created for high performance fibers that lack inherent ultraviolet (UV) resistance • Coating impregnates the individual fibers with a specialized resin for improved UV protection • Coating enhancements include UV inhibitors, absorbers and stabilizers • Improves the processing of the product via reduced filament snagging and friction • Low level water- blocking finish for any technical fiber or textile substrate • Provides water- blocked strength reinforcements for dry cable designs • Can absorb 5x to 15x its weight in water • Dust-free coating imparts a very soft fiber hand, advantageous to cable, rope, and other textile processes • Patented technology incorporates super absorbent polymer (SAP) suspended in a proprietary resin matrix • Used in the production of ‘dry-dry’ telecommunications, electromechanical, seismic, umbilical and power cables • Can absorb up to 100x its weight in water • Creates a stable gel when exposed to water • Functionally replaces flooding compounds, filling gels, spun SAF yarns, and water blocking tapes • Enables faster, more economical and robust cable manufacturing • Increases durability and abrasion resistance by encapsulating filaments in the fiber bundle • Extends the life of the product by reducing the effects of friction and yarn on yarn abrasion • Protects the fiber from degradation and filamentation • Ideal for high abrasion and high friction applications in a range of fiber constructions and environments • Wicking refers to the tendency of a yarn or other fiber to draw moisture into filaments via capillary action • Coatings designed to prevent moisture from wicking within and between fibers and strands • Protects Wire or Optical Fiber from damaging effects of moisture, which can cause a drop in signal and attenuation • Hydrophobic additives used to promote and enhance water repellancy in industrial applications • Creates a waterproof barrier that prevents moisture from further migration • Applied at various % levels to optimize for water-proof ratings • Designed to inhibit or slow the spread of fire/flame • Coupled to fibers with inherent flame and thermal resistance to boost performance • Added to fibers with weak flame resistance to improve burn rating SUITABLE FIBERS • Kevlar® Para-Aramid • Nomex® Meta-Aramid • Vectran® LCP • Zylon® PBO • Technora® Fiber • Carbon Fiber • Kevlar® Para-Aramid • Nomex®

Executive Vice President and CFO, will provide insights and commentary on the company's expected second quarter performance as well as the status of the previously announced Clariant Masterbatch acquisition.

Avient colorant solutions are available in liquid, solid masterbatch, and dispersion forms.

Avient is actively involved in various associations including the ACC, European MasterBatchers and Compounders (EuMBC), European Plastics Converters (EuPC) and Titanium Dioxide Manufacturers Association (TDMA).

Cesa™ bright masterbatches enhance the long-term white appearance of plastic products by converting UV radiation into a bluish light, providing better brightness retention than topical optical brighteners.

Cesa™ Mat masterbatch reduces gloss and creates a matte or frost-like effect invarious polymer products.
