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.

Work Glove Provides Cut Protection and Slip-Resistance

The SmartCut BKCR404 glove is designed with high-molecular-weight polyethylene fiber thread blend to ensure dexterity and tactile sensitivity.

The SmartCut BKCR404 glove is designed with high-molecular-weight polyethylene fiber thread blend to ensure dexterity and tactile sensitivity.

When the job calls for cut protection, slip-resistance, and surface protection, the Brass Knuckle SmartCut BKCR404 is the glove to use. This glove is ideal for handling finer-surfaces and finished goods, like glass, polished metals, painted or powder coat surfaces, ceramics and more.

BKCR404 is designed with high-molecular-weight polyethylene fiber thread blend to ensure dexterity and tactile sensitivity. This HDPE knit fiber provides ANSI cut level 4 protection without bulk. The polyurethane coating over palms and fingers is pliable, enhancing dry grip. When compared to nitrile and latex coatings, polyurethane offers a high level of dexterity and improves ergonomics.

The coating on the BKCR404 leaves minimal marking (residue)—even on glass, metal or other fine finishes. The BKCR404 is approved by PPG on its low emissivity (or low-e glass coated) products due to minimal marking and easy clean up.

Fit is a part of comfort, affecting both productivity and wearer compliance. These gloves reflect Brass Knuckle’s fit, form and function development methodology, wherein stitching, yarn combinations and coatings each account for the natural curvature of the hand and flex points.

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 Architectural Metal Coatings Binder Available in Downloadable Format

PPG Industries’ coil and building products coatings group announced that its Architectural Metal Coatings binder is now available online in a digital, downloadable format.

The digital binder features fully updated catalogs, product brochures and data sheets for PPG’s entire roster of PPG liquid coil coatings such as DURANAR and CORAFLON fluoropolymer and DURASTAR polyester coatings, and liquid and powder extrusion coatings such as Duranar and Coraflon fluoropolymer and ENVIROCRON polyester coatings.

The binder also contains PPG color guides, technical documents, white papers and case studies, along with sourcing information for PPG CAP CERTIFIED APPLICATOR PROGRAM group participants and PPG-approved extrusion applicators and coil coaters.

Sharon Bird, PPG marketing communications manager, industrial coatings, said that the new digital binder demonstrates PPG’s commitment to “green” building and design, and it will complement PPG’s growing array of online tools, including a newly enhanced searchable project gallery.

“PPG is committed to sustainable business practices. This new digital binder shows that commitment while giving architects, specifiers, coaters and applicators access to the latest product information from PPG, even when they are on the go,” she said.

PPG Publishes Info about Water-based ENVIRON MCL Coatings

PPG Industries’ industrial coatings business has published an informational guide about ENVIRON MCL coatings, an environmentally friendly, water-based coating for application on metallic coating lines over GALVALUME coated sheet steel and hot-dipped galvanized metal.

Environ MCL products provide a permanent coating that is superior to temporary anti-fingerprint coatings available on the market and extends the life of buildings by offering lasting aesthetics with enhanced solar reflectance (SR), ultraviolet (UV) protection and corrosion resistance. Available as a clearcoat or in a selection of colors, Environ MCL coatings have a minimum SR capability of 70, which enables them to reduce energy costs and improve comfort in metal building structures.

The guide includes performance specifications with data for dry film thickness, post-cure pencil hardness, solar reflectance, salt-spray and humidity resistance, accelerated weathering, and outdoor exposure.

As a water-based product with low VOC (volatile organic compound) content, Environ MCL coatings protect the environment by encapsulating zinc from the metal substrate to eliminate toxic runoff into the water supply. The coatings also can be applied on mill coatings lines, which can reduce costs by eliminating the need to send metal to a coil coater for processing.

Typical exterior applications for Environ MCL coatings include metal roofing, agricultural buildings, and shade and shelter structures. The coatings are also suitable for interior uses such as ceiling grids, structural steel, linear panels and roof decking.

PPG to Reintroduce DURANAR ADS Coatings

PPG Industries‘ coil and building products coatings group announced that it will reintroduce DURANAR ADS (air-dried system) fluoropolymer coatings this summer, three years after the products were withdrawn from the market.

This next-generation line of Duranar ADS coatings, based on a newly-formulated fluorinated copolymer resin combined with PPG proprietary chemistry, is designed to repair fluoropolymer coatings on architectural metals damaged during production or after field installation. In addition, these high-performance coatings can provide a wide range of color options for manufacturers and contractors in solid, metallic, pearlescent and infrared-reflective (IR-reflective) pigment technologies.

Brian Knapp, PPG manager, coil and building products coatings, said the reformulated products will fill a specific demand that has been unmet since first-generation Duranar ADS coatings were discontinued. “Other than acrylic lacquers, which are not very durable, there has not been a user-friendly product available for touching up fluoropolymer coatings on products such as window frames, door frames, roofs and metal wall panels marred during fabrication or installation,” he explained.

Because of its single-component formulation, Duranar ADS coating has the flexibility to be applied by fingernail brush for small touch-ups at the end of a production line or to be spray-applied in the field to repair or refurbish weathered metal roofing or siding panels.
