$122.48Cover 715 Poly Fluid from Graco 189635 delivers exceptional performance in demanding industrial environments. This two-component polyurea system features rapid reactivity and high solids content for a durable finish that can withstand abrasion, chemical exposure, and constant mechanical stress. Its formula combines an aliphatic isocyanate prepolymer with proprietary amine curatives, resulting in a dense cross-linked network within seconds of application. Contractors and production engineers appreciate its consistent viscosity, minimal spray pattern distortion, and compatibility with most heated proportioning pumps. Precision sprayers configured with appropriate tip sizes help optimize atomization and reduce overspray, yielding a uniform coating while minimizing waste.
Cover 715 Poly Fluid exhibits a near-zero VOC profile and a solids content approaching 100%, making it suitable for both interior and exterior applications. Formulation specialists have fine-tuned the polyurea ratio to deliver superior adhesion on substrates ranging from steel and aluminum to concrete. High cross-link density translates into excellent tensile strength and elongation, while the low dynamic viscosity ensures smooth pumping through spray lines. Equipment calibration remains straightforward, and cleanup requires minimal solvent. Operators rely on the graco 395 airless paint sprayer for precise metering and controlled fluid delivery at pressures up to 4,000 psi.
Seamless integration with heated hoses and proportioners is crucial for consistent performance. Recommended hose temperatures are typically maintained between 140°F and 160°F to prevent viscosity spikes and ensure optimal mixing in the spray gun manifold. A variety of static-ground fittings help prevent electrostatic buildup during high-speed spraying. Many applicators pair this fluid with stainless steel filter elements and ceramic-tipped nozzles to extend service life and maintain a uniform fan pattern. For heavy-duty projects, use the graco 490 paint sprayer equipped with a high-output motor and large-diameter hoses to sustain continuous throughput.
Effective post-job maintenance begins with a thorough solvent flush immediately after use. Flushing cycles clear residual polyurea from hoses, pumps, and gun passages before curing occurs. Operators should inspect static-ground connections, check for any wear in piston packings, and replace polyurethane seals within recommended intervals. Using compatible cleaning solutions reduces downtime and extends the life of check valves, manifold seals, and fluid section components. When selecting a backup system for heavy workloads, the graco 695 paint sprayer offers robust build quality, simple field servicing, and readily available replacement parts.
This polyurea blend retains integrity at sub-zero temperatures, maintaining flexibility down to -20°F without cracking. Steam exposure up to 212°F produces negligible loss of tensile strength. Aliphatic chemistry prevents UV-induced chalking, while a corrosion inhibitor package shields metal from salt-spray damage. Thermal cycling from -20°F to 180°F shows less than 5% mass change, enabling reliable performance on bridges, offshore rigs, and refrigerated facilities.
Opting for this polyurea provides fast set time and minimal downtime on critical assets. High thermal stability and corrosion resistance outperform standard epoxies in marine and chemical plants. Near-zero VOC content meets stringent environmental regulations, improving safety and compliance. Consistent rheology simplifies spray patterns and reduces overspray, while precise component ratios eliminate field mixing errors. Maintenance teams benefit from extended service intervals and fewer recoats.
Cover 715 Poly Fluid interfaces seamlessly with a wide range of spray gun kits and accessory modules. Optional fluid regulators, pressure gauges, and dual-component monitors help maintain accurate ratio control during extended runs. Heated hose extensions in various lengths accommodate large facilities and remote application points. For specialty requirements, modular filter assemblies can be installed to trap impurities and protect precision nozzles, reducing maintenance cycles and ensuring uninterrupted operations.
Cover 715 Poly Fluid complies with OSHA isocyanate handling rules and is produced under ISO 9001 standards. Mandatory PPE includes respirators and chemical-resistant gloves. Adequate ventilation should meet NFPA 33 requirements to control airborne contaminants. Full instructions are available in the Safety Data Sheet, ensuring operators adhere to best practices and maintain a secure application site.
