POLIGRAPH 70 PLUS RESIN

Pultrusión con grafeno

POLIGRAPH 70 PLUS RESIN

Medium-high viscosity, isophthalic polyester resin with graphene.

PROPERTIES

  • Fast curing cycle.
  • Excellent impregnation into the glass.
  • Fully compatible with pigments.
  • High mechanical properties.
  • High resistance to water, temperature.
  • 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.
  • The percentage of mek peroxide should be between 0.75% and 1.5%, although it can be increased up to
    2% to reduce gel time.
  • The application can be manual or by machine.
  • Can be used in pultrusion processes.
