Vinilgraph 901 LV Plus Premium Resin
Requires PMEC Catalyst X-8 for Catalysis.
Bisphenol A-type vinyl ester epoxy resin with graphene, featuring medium-low viscosity and reactivity. It offers excellent corrosion resistance against a wide range of organic and inorganic acids, alkalis, oxidising chemicals, saline solutions, etc. It also provides very good mechanical strength, such as tensile and flexural strength, when combined with reinforcements like fibreglass, carbon fibre, etc.
Technical Information
Properties
- High mechanical properties.
- Great chemical resistance.
- Excellent corrosion resistance.
- Improved thermal conductivity.
Applications
- Designed as a reinforcement for resin bases such as fibreglass, carbon fibre, etc.
- Good interlayer adhesion and very low linear and volumetric shrinkage.
- The percentage of MEK peroxide to be added ranges between 0.6% and 1%, although it can be increased to 2% to reduce the gel time.
- The application can be manual or by machine.
- May be used in pultrusion processes.
Storage and packaging
- The product must be stored in a dry place at a temperature not exceeding 25ºC.
