Since the binder systems are solid at room temperature, they can be produced by the existing methods used for powder coafingsd Solid resins, pigments, photoinitiators, and other additives are premixed, then melted and dispersed in an extruder at 100 to 130°C (212 to 266°F). The molten blend is then squeezed into a thin ribbon between chilled rolls. This ribbon is further cooled to near room temperature on a water-cooled cooling belt. The cooled ribbon is broken first into flake and then ground into a fine powder ready for use. The process is illustrated in Figure 7.15.

The formation of hydrolysis products, in the case of zinc phosphate, depends on the permeability of the protective coating. The permeability of the protective coating itself is influenced by the type of resin used, and in particular, by the PVC (Pigment Volume Concentration). This means that the choice of resin, pigments and fillers and the complete formulation have an important influence on the corrosion protection behavior of protective coatings containing zinc phosphate [5.69].

Ultrafiltration uses membranes that allow the passage of water and truly dissolved substances, such as solvents, solubilizers, salts (impurities), etc. Dispersed paint resins, pigments, etc., are retained by the membrane. One hundred or more gallons of bath pass on one side of the membrane under pressure, while 1 gal of clear aqueous fluid passes through the membrane. The fluid, called permeate or ultrafiltrate, is collected and used as rinse fluid. A three-stage rinse system recovers approximately 85% of the paint solids that were lifted from the bath.

The compositions of cathodic and anodic electrodeposition baths are given in Table 3.11. The main components are resins, pigments, extenders, some solvent, and neutralization agents. The latter are used to neutralize the charge on the resins so that they become water dispersible. The application data affect the plant and equipment technology (e.g., choice of construction materials, energy consumption, and rectifier design) [3.109], [3.117]. 

This subdivision is by no means exhaustive. Individual products cannot always be assigned to one of these groups because one additive may simultaneously influence a combination of paint properties. Additionally it is sometimes difficult to draw the line between additives and other paint ingredients (e.g., resins, pigments, extenders, and solvents) when these materials are used in an additive-like manner.

A representative selection of commercial color concentrates (Colortech Inc, Brampton, ON) were used for this study. Each pelletized sample consisted of a blend of organic and inorganic pigments dispersed in Linear Low Density Polyethylene (LLDPE) carrier resin. Pigment loading varied between 3,6 and 50.0 wt,% and some formulations contained up to 33.1 wt.% calcium carbonate filler. All were prepared on a production-scale 40 Liter Gelimat-style...
