The composites industry is without a doubt, one of the most demanding when it comes to quality. The more complex the requirements, the more important it is to offer an appropriate response.

Itasa offers maximum stability in release values and high resistance to temperature variations.

  • Consistent release on one or two sides
  • Release formulations designed for specific impregnation resins
  • Wide range of paper substrates and film so as to cover a wide variety of processes, relative humidity at the point of production and pre-pregging conditions
