The Supra HD SMP coil coating system is manufactured and distributed globally by Continental Coatings Inc. and Yung Chi Paint and Varnish Manufacturing Company Ltd. is a silicone-modified polyester high-durability coil coating system engineered for high-end metal building product applications and challenging exterior environments that require long life and extended warranty coverage. Supra HD system is formulated with a proprietary state-of-the-art polyester resin and silicone polymer system, which is significantly more resistant to UV-radiation and natural weathering than traditional polyester paints. Supra HD uses high-quality, long-lasting organic, ceramic, and metallic pigmentation to ensure excellent exterior color fastness and coating service life. This system is also available in multiple coats and various specialty high-build systems for custom projects and perforated applications. Supra HD may be applied Single Coat or over the Universal PU-11 High Molecular Weight Urethane Primer or PU-30 High-Build Urethane Primer Systems for extreme environment warranted building product applications.
Supra HD system is designed for trouble-free, high-line speed coil coating line application. It has been run worldwide under a very wide range of application parameters and substrate conditions. Standard topcoat DFT is .60-.80 mils, which allows for optimal application consistency, color stability, and exterior performance. Supra HD was formulated to provide improved stain resistance and cleanability, as well as scratch resistance and surface toughness, while maintaining the good system flexibility required for long-term bend line corrosion performance. Supra HD paint film is extra tough and can handle difficult roll-forming, panel stacking, and transport conditions. Superior primer corrosion resistance and substrate adhesion provide significantly enhanced protection against wet stack storage problems, cut edge, and scratch corrosion.
Supra HD system can be formulated in standard, medium, textured, and low gloss/low sheen finishes and supplied in a wide range but with limited color palettes. This premium coating supports an extended warranty and can be applied to a variety of adequately cleaned and treated metal substrates including: Hot Dipped Galvanized, ZnAl, Galfan®, ZAM®, and Aluminum. Supra HD can be formulated with COOL ROOF ceramic pigment technology and can be formulated to exceed ENERGY STAR® requirements. It is ideal for metal wall panels, industrial and agricultural metal building components, premium rainware, commercial and residential metal roofing, and pre-engineered metal building system applications.
