Extruder Offers Low-Torque Compounding
The Compex Multi-Process Compounder is designed for the low-torque mixing of powder coating formulations. It is available in screw diameters from 25 to 85 mm. Nonintermeshing and back-flow elements work together to thoroughly mix polymers. The smooth, continuous torque minimizes shear force and allows gentle and uniform incorporation of additives and temperature-sensitive materials.

Extruder
Features Side-Feed System
The PCS
extruder for powder coating manufacturing incorporates a side-feed system that
optimizes feeding of premix, fines and rework. It is available in 8 L/D and 11
L/D working lengths and five screw diameters ranging from 46 to 140 mm. Users
benefit from the extruder's wide processing window, increased screw speed, good
thermal control and high throughput rates.

Pigments
for Easy Bonding
Afflair PC DB
and PC S pearlescent Lustre pigments are designed for dry-blending into
pigmented powder coatings. They reduce or eliminate problems in dispersion,
separation, buildup, and puffing and spitting. The PC S pigments are specially
treated for use in bonding processes. They offer superior leafing, leveling and
flow properties; good luster and color; re-duced pigment loading; and easy
bonding.

Specialty
Pigments Produce Glitter Effect
Firemist
special-effect glass flake pigments add a brilliant glitter to coatings. This
line of titanium dioxide-coated borosilicate flakes provides excellent chroma,
color purity, brightness, transparency and reflectivity. The glass in the
pigments promotes light penetration, building a sense of depth. Multicolored
effects can be created by blending the pigments.

In-line
Classifier Obtains High Yields
The MikroCut
classifier can be installed as a stand-alone classifier or in-line for process
integrated operation in the removal of fine particles while obtaining a higher
yield of final product. Fines content of 25 to 30% less than 10 µm by volume
are reduced to approximately 8 to 10% with a course material yield of 85 to 95%,
resulting in lower operating costs and reduced waste. It is available for feed
rates from 60 to 3,500 pounds per hour.

Degassing
Agent Enhances Color Stability
Powdermate
542DG degassing agent provides good debubbling coupled with improved resistance
to discoloration in all standard powder coating resin systems. It protects
clear- and light-color systems from yellowing under all curing conditions.
