PPG Celebrates Anniversary of PVDF Coatings

PPG has announced that it is celebrating the 50th anniversary of DURANAR coatings throughout 2017, commemorating the introduction in 1967 of the polyvinylidene fluoride (PVDF) coatings for metal building components.

Over the past half-century, Duranar coatings have been specified by architects to protect and enhance architectural landmarks, such as the Empire State Building in New York, the Louvre Pyramid in Paris, Shanghai World Financial Center in China, Petronas Towers in Kuala Lumpur, Malaysia, and the Rock and Roll Hall of Fame in Cleveland.

PPG has refined Duranar coatings since its introduction to meet evolving aesthetic, performance and sustainability demands of architects and building owners. Advances have included adding metallic flakes and other effects for appearance options; incorporating ULTRA-COOL infrared-reflective pigments to help reduce building-cooling loads; and formulating Duranar powder coatings, which earned PPG a R&D 100 Award recognizing the coatings’ ability to reduce volatile organic compound (VOC) emissions and economize production of custom-colored powder coatings.

Brian Knapp, PPG director, coil and building products, said Duranar coatings have been popular with architects and building owners for their blend of aesthetics, reliability and performance. “Duranar coatings can be formulated to provide a range of colors and effects, giving architects an unlimited design palette,” he says. “They also feature a chemistry developed and refined by PPG that has delivered decades of color retention and chalk and chemical resistance, even in seacoast and industrial environments.”

Duranar coatings are formulated with PPG resins and pigments in combination with standard KYNAR 500 or HYLAR 5000 PVDF resins. In fact, PPG helped popularize and improve PVDF coatings technology by licensing Kynar 500 resin, which was originally commercialized by Pennwalt Corp. in the mid-1960s. PPG remains the original and continuous licensee of this PVDF resin, which has become an industry standard.

PPG’s formulation for Duranar coatings creates molecular bonds that render the material almost impervious to the effects of continuous ultraviolet (UV) exposure, as well as other environmental and atmospheric hazards such as salt air, humidity, high temperatures and acid rain. In fact, many of the original trial panels coated with Duranar products PPG developed 50 years ago are still enduring exposure testing in South Florida.

As part of the anniversary celebration, PPG will highlight Duranar coatings in trade-show displays throughout the year, offering customer promotions and giveaways. PPG also will introduce a web portal featuring images and descriptions of buildings finished with Duranar coatings, as well as articles, white papers and other educational materials.

Steelscape Now Offers Graffiti-resistant Coatings from PPG

PPG Industries’ building products group announced Steelscape is now offering metallic-coated and pre-painted steel with DURANAR GR (graffiti-resistant) and CORAFLON GR coatings.

Duranar GR and Coraflon GR three-coat systems feature a primer and color coat topped with a graffiti-resistant clearcoat that can be cleaned with DURAPREP Prep 400 graffiti remover by PPG. If the Steelscape steel is spray-painted, graffiti can be eliminated by applying the graffiti remover directly to the stain, allowing it to sit for 10 to 60 seconds, then wiping it with a clean cloth or scrubbing it with a nylon brush. Most stains can be removed in 10 minutes or less.

When applied on either Duranar GR or Coraflon GR clear coatings, Duraprep Prep 400 field-applied graffiti remover also can eradicate paint overspray, pen and marker ink, lipstick, scuff marks, tape residue, bugs, tar and many other substances that mar the appearance of steel building panels.

Duranar GR coatings are available in a variety of low and medium glosses; Coraflon GR coatings are for high-gloss finishes.

PPG Industries Publishes ‘Building Products Coil Coatings Color Guide’

PPG Industries’ coil and building products group has published the “Building Products Coil Coatings Color Guide”, an eight-page brochure featuring 100 coatings color samples categorized according to eight product lines and five resin chemistries.

The booklet highlights 30 individual colors, ranging from regal and bright white to charcoal and solar-reflective black, for DURANAR ULTRA-COOL polyvinylidene fluoride(PVDF) coatings, DURASTAR polyester coatings and Durastar SMP (silicone-modified polyester) coatings. There are five color samples each for Duranar ULTRA-Cool SUNSTORM coatings and three-coat Duranar XL ULTRA-Cool coatings.

ULTRA-Cool coatings by PPG are formulated with proprietary infrared (IR)-reflective pigments and resin technologies that deflect solar heat from buildings, enabling them to stay cooler and consume less energy for air conditioning.

The guide features 10 Duranar VARI-COOL coatings, which combine ULTRA-Cool coatings technology with color-changing polychromatic pigments, along with 10 DURAFORM BP coatings, which are part of a new line of next-generation engineered polyester-resin-based products. Readers also will find five color swatches each for ENVIRON waterborne acrylic coatings and PLASTICRON plastisol-based coatings.

PPG coil coatings are designed to meet a wide range of building applications, from high-end roof and wall panels for monumental buildings to industrial plants, agricultural buildings, garages, warehouses and other utilitarian structures. With their broad color range, PPG coil coatings provide durable, colorfast protection to soffits, gutters, heating and air-conditioning ducts, trim coil and rainware due to their exceptional hardness and resistance to abrasion, chalking, ultraviolet (UV) radiation, moisture, corrosion and weather.
