VINILGRAPH 40 PLUS RESIN

Pultrusión con grafeno

VINILGRAPH 40 PLUS RESIN

Epoxy vinylester resin, diluted in styrene, of medium viscosity and reactivity. It is pre-accelerated with cobalt salts.

PROPERTIES

  • High mechanical properties.
  • High chemical resistance.
  • Excellent corrosion resistance.
  • Improvement of thermal conductivities.

APPLICATIONS

  • It is specially designed as a base resin for fibreglass work.
  • It has good intercoat adhesion and very low linear and volumetric shrinkage.
  • Inert mineral fillers such as calcium carbonates, calcium sulphates, dolomite or silica can be added. The percentage of mek peroxide to be added is between 0.75% and 1%, although it can be increased to 2% to reduce the gel time.
  • The application ca be manual or by machine.
  • Can be used in pultrusion processes.
