Polyester Gelcoat Epoxy Compatible

  • Pre-accelerated
  • Airless version available
  • Epoxy compatible

RESOLCOAT 9040 PX is a polyester gelcoat available in a wide range of colours. Its special formulation allows for good adhesion properties with epoxy resin systems. RESOLCOAT 9040 PX combines the advantages of the perfect surface finish of a polyester gelcoat with the superior mechanical performance of an epoxy laminate.

MIXING RATIO

RESOLCOAT 9040 PX is a polyester system. Catalyst should be added to promote the cure.
The level of catalyst to add should be between 1.5% and 2.5%.

Catalyst should be PMEC at 50%.
RESOLCOAT 9040PX is supplied pre-accelerated.
We advise to stir the gelcoat prior to mixing the catalyst.

APPLICATION

RESOLCOAT 9040PX can be applied by brush or airless spray. It is available in two versions with different viscosities. For spraying applications, it is possible to add solvent. If acetone is to be used, it should not exceed 10%. Workshop temperature should be between 18°C and 25°C. Humidity level should be below 85%.

For more information, please refer to the applications technical bulletins (TechNotes), available on request.

Film thickness should be between 300 and 500 microns, depending on the type of product manufactured.

We do not advise using RESOLCOAT 9040PX for the manufacture of moulds or for applications in contact with highly corrosive chemicals.

In case of first time use of this product, we advise to carry out a test with the selected epoxy laminating system.

CURING

The curing process is similar to all polyester gelcoats. We advise allowing at least 1H 15mn and 3 hours depending on the ambient temperature prior to overcoating the gelcoat.
