Introduction
Material preparation is crucial when working with substances like polyurethanes, epoxy resins, silicones, and greases. This process addresses issues such as sedimentation, air bubbles, and dissolved air to ensure high-quality dispensing.

Material Preparation Techniques
Degassing: To remove air bubbles and dissolved air, materials are degassed using a vacuum. The mta CFD continuous flow dispenser, which utilizes a progressive cavity pump, is employed to extract material from the supply tank without introducing air inclusions.

Homogenization and Degassing: For filled products, simultaneous mixing and degassing are performed to ensure a homogeneous, air-free product.

Supply to the Dispenser
Various supply methods are used depending on material viscosity:

• Low Viscosity: Gravity flow is used by positioning the tank outlet above the dispenser.
• Low to Medium Viscosity: Pneumatically pressurized tanks facilitate fluid movement to the dispenser.
• High Viscosity: A supply pump is installed under the tank to overcome pressure losses, especially when the distance to the dispenser is significant or inlet pressure is high.

Conclusion
These flexible solutions ensure the delivery of high-quality dispensed materials by addressing specific challenges associated with different material types and viscosities.
