System Overview

Rb3™ SMP coil coating system manufactured and distributed globally by Continental Coatings Inc. and Yung Chi Paint and Varnish Manufacturing Company Ltd., is a Premium Silicone Modified Polyester (SMP) coil coating system engineered for high end metal building product applications and challenging exterior environments that require long life and extended warranty coverage. Rb3™ system is formulated with a proprietary state of the art polyester resin and silicone polymer system, which is significantly more resistant to U.V. radiation and natural weathering than traditional SMP paints. Rb3™ uses the highest quality long lasting ceramic and metallic pigmentation to insure optimal exterior color fastness and longevity. This system is also available in multiple coats and various specialty high build systems for custom projects and perforated applications. Rb3™ may be applied over the Universal PU-11 High Molecular Weight Urethane Primer or PU- 30 High-build Urethane primer systems for extreme environment and extra long service life warranted building product applications.

Application Parameters

Rb3™ system is designed for trouble free high line speed coil coating line application and has been run worldwide under a very wide range of application parameters and substrate conditions. Standard topcoat DFT is .70-.80 mils, which allows for optimal application consistency, color stability and exterior performance. Rb3™ 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. Rb3™ paint film is extra tough and can handle difficult roll forming and panel stacking and transport conditions. Superior primer corrosion resistance and substrate adhesion provide significantly enhanced protection against wet stack storage problems of cut edge and scratch corrosion.

Commercial Uses

Rb3™ system can be formulated in standard, medium, textured, and low gloss/low sheen finishes and supplied in wide range but limited color pallet. 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®, Aluminum, and Stainless Steels. Rb3™ is formulated primarily with IR Reflective COOL ROOF ceramic pigment technology and can be designed to meet and exceed U.S. Energy Star®requirements. It is most ideal for Metal Wall panels, Industrial and Agricultural Metal building components, high- end equestrian applications, commercial and residential Metal Roofing, and pre-engineered Metal Building System applications.
