Arkema, industrial partner to Chinese glass manufacturer Qinhuangdao Yaohua

Published on 2006-06-15. Author : SpecialChem

Arkema partners Chinese glass manufacturer Qinhuangdao Yaohua for the production of next generation CVD Low E flat glass, developed jointly by Arkema and Stewart Engineers.

Arkema, a world leader in glass coatings for the flat glass industry, announces it is to partner, through its subsidiary Arkema Inc, a second glass production line project at Qinhuangdao Yaohua, China's leading hard coated(1) glass producer. This new line will use the next generation CVD (Chemical Vapor Deposition) Low E(2) process, jointly developed by Arkema and its engineering partner Stewart Engineers.

This second production plant using Arkema's CVD Low E coating system will allow Qinhuangdao Yaohua to add additional capacity for the hard coated Low E grades within its range of thin glass and solar control glazing products in 2007. This expansion comes two years after a successful startup of the first line. The products from this partnership will fulfill the growing demand of the local market, while providing Qinhuangdao Yaohua with strong assets to maintain its leading position in hard coated glass in China.

Arkema's Certincoat® CVD coatings produce glass with optimum year-round thermal efficiencies. They are particularly suitable in heating-dominated climates, and outperform "high performance" sputtered MSVD competitive coatings. CVD-treated glass offers two major benefits in terms of energy savings: it reflects the heat from within the room, and features a high solar heat gain coefficient.

  1. "Hard coated"refers to glass coatings using the CVD (Chemical Vapor Deposition) system. These coatings have unlimited lifetime. Also available are "soft coated" coatings, obtained by the sputtering process called MSVD (Magnetron Sputtering Vacuum Deposition). Their lifetime is limited to a few months, and they require specific storage and handling conditions to prevent deterioration.
  2. "Low E" or "low emissivity": emissivity refers to a glass coating's ability to absorb or reflect infra-red rays and hence heat. "Low emissivity" or "Low E" glass therefore absorbs very little heat.

Arkema's Certincoat® coatings

For more than 20 years, Arkema's Flat Glass Coatings Group has been providing innovations in coating materials, processes and proprietary coating systems - from floatline-applied low emissivity coatings to off-line conductive coatings for special applications, including insulated windows, storm windows and windows for appliance doors. Certincoat® Low E Coatings are offered by many window manufacturers nationwide.
