New Mexico School Features Eco-Friendly Anodized Walls

By: Tim Pennington 4. May 2012

 
The first new elementary school in New Mexico's Bernalillo Public Schools district in 30 years features anodized storefronts and curtainwalls that send 90 percent less waste to landfills.
 
Linetec finished the storefront and curtainwall systems' aluminum framing members for Bernalillo Elementary School applying paint on the interior and clear anodize on the exterior. This eco-friendly anodize process sends 90 percent less waste to landfills than traditional anodizing.
 
The eco-friendly etch process creates an aesthetically appealing "frostier" appearance that helps hide small defects, such as die lines, flow lines, minor corrosion and scratches, that may occur on the aluminum surface of architectural products. Although neither conventional caustic nor acid etch removes all irregularities in the aluminum, acid etch does a better job of concealing them. This gives the material a better aesthetic finish on both primary and secondary (recycled) billet.
 
Linetec's eco-friendly anodize process meets or exceeds all AAMA 611 specifications. Standard warranty of 5 years and optional extended 10 year warranty apply.
 
Painted finishes also are applied and controlled in an environmentally effective manner to minimize, or even eliminate, volatile organic compounds (VOCs). These architectural-grade finishes help minimize maintenance and further protect the entrance systems' rigorous operation.
 
Bernalillo Elementary School serves approximately 450 third- through fifth-grade students and faculty. Previously, these students attended Carroll Elementary, which was built in 1980 as the district's last "new" elementary. The kindergarten through second-grade students attended Roosevelt Elementary. When the new elementary opened in August 2010, Carroll became the kindergarten through second-grade campus and Roosevelt transitioned to administrative offices.

PPG Aerospace Coatings Create ‘All Black’ Livery For Air New Zealand

“Green” coatings by PPG Industries’ aerospace business were specified by Air New Zealand for the black livery on four airplanes that are part of the airline’s sponsorship of the New Zealand Rugby Football Union and the world champion All Blacks rugby team.
 
Air New Zealand has taken delivery of a new Boeing 777-300ER airplane and subsidiary Eagle Airways has had two Beechcraft 1900D airplanes repainted with PPG Aerospace’s environmentally responsible coatings system: DesoGel EAP-9 metal pretreatment, DESOPRIME CF/CA 7502 epoxy primer and DESOTHANE HS topcoats. Eagle Airways also plans to have a third Beechcraft 1900D turboprop repainted in the black livery.
 
Air New Zealand commissioned the dramatic livery, featuring an all-black fuselage with a silver fern (symbolic of New Zealand) overlay across the rear of the aircraft to celebrate sponsorship of the All Blacks through 2015.
 
“New Zealand is crazy about rugby,” said Richard Wilkinson, PPG sales manager at the aerospace application support center in Tullamarine. “As the national carrier, Air New Zealand and its Eagle Airways subsidiary are keen to protect New Zealand’s unique natural environment. Using these PPG Aerospace products enabled them to do so without compromising performance.”
 
Instead of using chromates for metal corrosion resistance, DesoGelEAP-9metal pretreatment and Desoprime CF/CA 7502 primer inhibit corrosion with a chromate-free formulation, Wilkinson said. Additionally, he said Desothane HS topcoats by PPG Aerospace contain less volatile organic compounds than conventional paints to reduce greenhouse gas emissions. “Drying times for these topcoats can be accelerated with thinners, minimizing energy consumption compared with other paints that rely on heat to speed up the drying process. This is especially important when applying markings,” Wilkinson said.
 
Air New Zealand and Eagle Airways will maintain the glossy appearance of their black aircraft with Desoclean Green dry wash and polish by PPG Aerospace, which reduces the amount of required wet washing. Eagle Airways opted for the additional protection of a clearcoat.
 
Aviation Painting Services (APS), Hamilton, New Zealand’s newest full-time aviation painting operation, painted the Eagle Airways Beechcraft 1900D airplanes, while Boeing painted the Boeing 777 at its Everett, Wash., facility.
 
According to Phil Byrne, APS general manager, the project was a challenge because a complex livery had to be applied in a limited timeframe.
 
“Some of the pressure was reduced with the knowledge that Air New Zealand had chosen PPG products, which are known to be great to apply,” Byrne said. “Plus they are backed up with the PPG promise of technical support.”
