How to Use PRIMACOR - Powder Applications
Polyolefins such as PRIMACOR* copolymers are often sold as small pellets. However, well-known grinding techniques can transform the pellets into free-flowing powders. In such form, PRIMACOR copolymers are used in such diverse applications as powder coatings and nonwovens binders.
In the powder coating market, a unique combination of properties gives PRIMACOR copolymers a clear advantage over other polymers. Compatibility with many fillers, pigments, and additives gives the flexibility to tailor the coating color and performance to your needs. With the addition of sufficient light stabilizer, outdoor applications are not even a problem. The excellent adhesion of PRIMACOR copolymers to many metals provides the base a coating needs for an extended service life. High toughness and impact resistance result in abuse not possible with other coating systems. The high flexibility of these polymers even allows bending and flexing of the substrate without coating failure. In addition, PRIMACOR copolymers are resistant to many polar and non-polar chemicals.
The adhesive qualities of PRIMACOR copolymers are also useful in the nonwovens industry. When applied as a powder to loose fibers, PRIMACOR copolymers can be thermally bonded to create a strong, water-resistant nonwoven. No water is driven off (as with aqueous systems) and no curing mechanism is required (as with thermosets). High line speeds can be achieved without the capital expense and high operational costs of ovens for water removal and curing. With excellent adhesion to many natural and man-made fibers and many metal and plastic substrates, PRIMACOR copolymers can perform the dual role of binder and adhesive.
