Vinilgraph 901 Plus Premium Resin
Requires PMEC Catalyst X-8 for Catalysis.
This bisphenol A vinylester epoxy resin, enhanced with graphene, features medium-low viscosity and reactivity. It offers excellent corrosion resistance against a wide range of organic and inorganic acids, alkalis, oxidising chemicals, and salt solutions. Additionally, when reinforced with materials like fibreglass or carbon fibre, it provides outstanding mechanical strength, including tensile and flexural resistance.
Technical Information
