ThixatropeActivation- How it Works

10

Wetting/Deagglomeration

• 15’- 20’ mixing @ ambient temperature

Dispersion/Activation/Dwell Time

• 15’- 20’ dispersion @ target processingtemperature

Cool Down

• Agitate! (castor based)• Cool to below target

activation temperature

THIXATROL® PM 8058INTRODUCING A NEW APPROACH

• Less influence on performance by polar solvents like alcohols – e.g. Benzyl

alcohol

• Higher Efficiency

• Low temperature activation

• Broad activation window

• Flexible and easier to incorporate

Conclusion

Conclusion

23

• THIXATROL® PM 8058 provides high performance• Proven in 2 C Epoxy system

• Includes variation in solid content and different formula ingredients

• THIXATROL® PM 8058 provides a better compatibility when formulation contains high level of various alcohols (Iso-Butanol, n-Butanol or Benzylalcohol)

• Performance is more stable

• Improved paint storage stability at 50 °C

• THIXATROL® PM 8058 provides a broad activation window from 45 – 75 °C• Offers greater flexibility in paint production

• Lower temperatures= energy savings

• Cost savings when replacing competition due to the higher effeciency

• Lower loading level has a less pronounced influence on secondary paint properties (e.g.adhesion)

• 82% based on renewable raw materials for sustainable formulations
