Arkema Inc. Provides Guidelines to Estimate Topcoat Color Fade

Arkema Inc. presented recommended guidelines for estimating the color fade of PVDF-based topcoats for bright color architectural restoration and protective coating applications at the SSPC 2017 Conference in Tampa, Fla.

This year’s SSPC Conference served as an international forum at which contractors, consultants, inspectors, engineers, paint/equipment manufacturers and structure/facility owners exchanged research and technologies in the coatings industry. The event’s GreenCOAT technical program emphasized innovations, the latest advances in eco-conscious coating technology and developments for complying with green regulations.

Many common topcoat standards used for architectural and protective coating applications include a durability requirement based on the accelerated weathering performance of a white coating. However, there are currently no standards for field-applied coatings that address the needs of specifiers who want to ensure color performance in high-chroma (saturated or bright) colors.
 
Dr. Kurt Wood, a principal scientist in Arkema’s Fluoropolymers R&D Division, reviewed data for coatings made using a range of pigment chemistries, enabling estimates of color lifetime to be made for virtually any color, if one stays within the particular resin chemistry space. These principles were demonstrated with PVDF-based topcoats, where it was found that both the pigment grades and the resin are important factors for determining the color lifetime, along with the pigment volume concentration.   

Complete Cool Roof System Extends the Service Life of New and Existing Roofs

Rhino Linings Corp., a manufacturer and distributor of spray-on protective linings, coatings and foam, released a complete cool roof system engineered to improve building energy efficiency while extending the service life of new and existing roofs.

The DuraTite spray polyurethane foam (SPF) roofing system holds a UL 790 Class A fire rating and is designed to provide a lightweight insulation system over various roof constructions and configurations. Unlike traditional roofing methods, DuraTite SPF roofing system offers a high R-value for superior thermal insulation, covers complex geometrical shapes and protrusions and applies directly to existing substrates in new and retrofit applications.

In addition to DuraTite SPF roofing system’s high-performance, it also offers significant life-cycle cost savings. An SPF roofing system is seamless and requires little-to-no maintenance. Roofing topcoats, like DuraTite acrylic, silicone, urethane and polyurea coatings may be reapplied numerous times, increasing the life of the roof.

The complete system combines spray foam with a full range of acrylic, silicone, urethane and polyurea coatings for a total roofing system that insulates, seals and protects. Products in this system include:

  • Acrylic Coatings — DuraTite 1065 and DuraTite 1070 single component, acrylic roof coatings demonstrate excellent adhesion to polyurethane foam, concrete, masonry, primed metal, primed wood and primed asphalt roofs. When applied at 12 DFT (dry film thickness) and fully cured, DuraTite 1065 and 1070 exhibit exceptional weatherability and resistance.
  • Silicone Coatings — DuraTite 1380 and DuraTite 1395 are high-solid, single-component, silicone coatings with low VOCs and excellent chemical and abrasion resistance. When applied, DuraTite 1380 and 1395 form a breathable membrane, making it an ideal choice for new and recoat applications over metals, single-ply membranes, masonry block, concrete and spray polyurethane foam roofing systems where moisture may be present.
  • Urethane Coatings — DuraTite 1175 and DuraTite 1285 are high-solid, single-component urethane coatings that can be applied in a wide range of ambient temperatures and humidity levels. Both offer superior impact and crack resistance. DuraTite 1285 also offers enhanced UV stability.
  • Polyurea Coatings — DuraTite 2185 is a fast set, rapid cure, 100 percent solids, plural component aluminized polyurea spray-applied lining offers enhanced UV stability and remains flexible in cold temperatures. DuraTite 2185 demonstrates exceptional adhesion to spray polyurethane foam, concrete, bitumen and asphaltic roofing felts, steel, wood and most substrates in extreme cold and warm climates.
  • Spray Polyurethane Foam — DuraTite CC 2.5, DuraTite 2.8 and DuraTite 3.0 closed-cell polyurethane foam products’ lightweight, seamless construction ensures leak-proof performance and allows for value engineering labor and material cost savings.

DuraTite SPF roofing system guide specifications and five-, 10-, 15- and 20-year warranties are available for use on roof substrates, such as metal, built-up roof membrane, single ply, wood recoat and concrete.
