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®
