Arkema’s Clearstrength® XT100: Better Dispersion = Limited Impact on Viscosity

Gone are the days of being stuck with standard core-shell modifiers. No more will we have to suffer through a lack of toughness and increased viscosity. Arkema and Palmer Holland are proud to introduce Clearstrength® XT100. XT100 is a toughening agent designed to meet the most demanding technical requirements expected of thermoset applications such as structural adhesives and high performance composites.

Clearstrength® XT100 is an easily dispersible powder that provides outstanding viscosity control which translates to better application properties. For example, many composite materials made from an infusion process can see a significantly increased viscosity of the host system when introduced to other core shell impact modifiers. This effect is drastically reduced when using XT100 (see Fig. 1).

Why use Clearstrength® XT100?

• Easily dispersible powder in most liquid resin systems
• Exhibits limited effect on liquid resin system viscosity
• Provides outstanding toughening effect in a wide range of service temperatures
• Increases toughness of thermoset systems
• Replaces standard core-shell modifier powders as well as liquid masterbatches of pre-dispersed core-shell particles
• Easily dispersed at very low shear rates
• Best balance of properties. See Fig. 2 with XT100 in a methacrylate structural adhesive formulation
