Product Uses
  • Clearstrength® XT100 is particularly recommended to increase the toughness of thermoset systems such as structural adhesives (e.g. methacrylates, epoxies, etc.) and composites.
  • Recommended loading levels depend on fi nal application and associated technical performance requirements.
  • Clearstrength® XT100 can be advantageously used to replace standard core shell modifi er powders but also liquid masterbatches of pre-dispersed core shell particles.
Dispersion Information
  • Clearstrength® XT100 powder can be dispersed with low to medium shear conditions in acrylic and polyesters at room temperature.
  • Medium shear conditions in temperature can be used for dispersion in epoxy resins.

Classical Reactive Diluents like 1,6-hexanediol diglycidyl ether (RD1) or 1,4-cyclohexanedi-methanol diglycidyl ether (RD2) are excellent solvent for Clearstrength® XT100 powder. They allow a great decrease of the viscosity and a new compromise of toughness versus Tg is achievable.
