Graphenano Poligraph - Model 70 Plus Premium -Graphene Reinforced Polyester Resin

Graphenano's Poligraph 70 Plus Premium is a specialized polyester resin enhanced with graphene, designed for applications requiring medium-low viscosity and thixotropic properties. This resin requires the PMEC Catalyst X-8 for catalyzation, ensuring optimal curing and mechanical performance. Its technical formulation offers enhanced mechanical properties, particularly when reinforced with 75% fiberglass, making it suitable for various industrial applications. The resin is available in different packaging sizes, including 5 kg, 20 kg, and 220 kg options, providing versatility for diverse project scales. Designed for professionals seeking reliable and high-performance materials, this resin supports various manufacturing processes requiring durable, stable, and resilient polyester solutions.
