Coil & Can
Coil coatings are used to coat steel or aluminum
coils (up to 3000 m long). It is a continuous process where coatings are usually
applied with a roller and baked at high temperature. The coated strips are re-wound
and can be cut, shaped and processed later to manufacture
the desired goods. Major end-use applications include building components (roofing,
siding, garage doors), transportation and appliances.
1K polyurethane coil coating universal primers are used in all applications
requiring a high degree of flexibility, crack-bridging properties to ensure corrosion
protection,
adhesion and versatility. Universal primers can be overcoated with all kinds
of topcoats.
Polyurethane technology is also used for high-built and textured 1K formulations
(primers + topcoats) to replace PVC Plastisols. These systems show very good formability,
chemical and abrasion resistance.
Thanks to their non-yellowing and gloss retention properties,
dark-colored 1K polyurethane topcoats are well established for wall and roof panel
applications.
In the can coatings area, polyurethane-modified
basecoats and clearcoats are widely used to coat tubes, aerosol cans, screw caps
and two-part beverage cans. They are also well established as topcoats for general
fine packagings.
