Features & Benefits
- Materials Features
- Key Features
- Methylmethacrylate-Butadiene-Styrene (MBS) core shell
- Tailored for epoxy thermosetting resins
- Optimized to the most demanding applications
- Matching low temperature requirements (toughening, elongation, lapshear)
Applications & Uses
- Product Uses
- Clearstrength® XT151 is particularly recommended to Increase the toughness of epoxy thermoset systems such as structural adhesives and composites.
- Loading levels depend on fi nal application and associated technical performance requirements.
- Clearstrength® XT151 can be advantageously used to replace standard core shell modifier powders but also liquid masterbatches of pre-dispersed core shell particles.
- Dispersion Information
- Clearstrength® XT151 powder can be dispersed in epoxy preferably with a medium shear mixer in temperature.
- Dilution of high core shell content preparation can be achieved with standard anchor blade homogenization.
EXAMPLE OF DISPERSION CONDITIONS Doseage 15-20 wt% Temperature 80°C Mixing Time 1 h Mixing Shear Medium Example of dispersion conditions with dispersive blade
Enhancing compatibility reaching dispersion at the individual core shell in most high Tg and more polar epoxy systems.

Technical Details & Test Data
- Toughening of High Tg Epoxy
Tg (°C) Lap Shear (MPa) K1C (MPa/m) GIC (J/m²) Neat 0.6 88 Standard MBS Powder (5 wt %) No Shift 6.2 1.1 380 Clearstrength® XT151 (5 wt %) No Shift 7.9 1.7 650 Clearstrength® XT151 yields superior toughness and shear adhesion strength than Standard MBS powder in high Tg epoxy (Tg>200°C).
- Overall Superior Performance in Epoxy
- Tensile Properties (23°C) – Cured Epoxy
Example of higher elongation at break reached in medium Tg Epoxy system
- Viscosity Influence in DGEBA Resin (23°C)
Lower viscosity in epoxy at high dosage of core shell particles allows higher additive concentration in applications where solution viscosity could be a limitation like in composite infusion, prepreg, and coatings.
