• Outstanding corrosion protection
• Formulation, processing and curing robustness
• Weatherable coatings

Polyurethane powder coatings exhibit excellent application and performance characteristics and offer the smoothest films available. The RUCOTE 100 resin series can be formulated in a wide variety of powder coatings with high-gloss, textured, matte and sand finishes. Polyurethane powder coatings are especially useful in automotive, outdoor furniture, lawn and garden, and general industrial applications. In addition, the RUCOTE 100 resin series can be used to formulate TGIC-free systems.

Epoxy polyester hybrid powder coatings are ideal for interior applications and exhibit good mechanical properties, corrosion resistance and overbake stability. The RUCOTE 500 resin series can be formulated in a wide variety of powder coatings with high-gloss, river textures, matte, metallic, hammertone and sand finishes. These hybrid powder coatings are especially useful in appliance, shelving, office furniture, fixtures and general industrial applications. Hybrid formulations can be modified to meet most of the demands of today’s market, both decorative and functional. The RUCOTE 500 resin series includes polyesters designed to react with epoxy resins in standard powder formulation ratios (50:50, 60:40 and 70:30).

Polyester powder coatings exhibit good flow properties, wear resistance and overbake stability. Super-durable polyester formulations retain color and gloss in harsh exterior applications. The RUCOTE 900 resin series can be formulated in a wide variety of powder coatings with high-gloss, satin, metallic and sand finishes. Polyester powder coatings are especially useful in architectural, container, shopping cart, lawn and garden, agricultural and construction equipment applications. The RUCOTE 900 resin series includes polyesters designed to pass both American Architectural Manufacturers Association (AAMA) standards 2603 and 2604. Non-blooming, zero T-bend and low-temperature cure resins are available.
