New Epoxy Coating From Devoe/Prufcoat —Literature Available
A new epoxy polyamide coating with the corrosion resistance of coal tar epoxy, but without its application or toxicity problems, has been introduced recently by Devoe/Prufcoat, Devoe & Raynolds Co., a division of Grow Group, Inc.
Known as CHEM-TAR™ High Build Epoxy Coating, it may be applied wherever conventional coal tar epoxy is specified and gives steel and masonry excellent abrasion and corrosion resistance to sewage, oil, alkali, dilute acids, fresh water, and salt water.
A c c o r d i n g to the company, CHEM-TAR Epoxy is easily applied and has an extended recoat time of up to seven days for immersion service, and up to 60 days in non-immersion service. It will cure effectively at temperatures down to 40° F, and features a high film build (8.0 mils dry film thickness). Other advantages include fewer health hazards because of low toxicity levels and excellent package stability for more than one year.
Steel surface preparation requires a near white blast (SSPCSP10) in severely corrosive areas, and a commercial blast (SSPCSP- 6) in moderately corrosive areas. Normally applied by spray application in two coats at 8.0 mils dry per coat, CHEM-TAR Epoxy is self-priming on most surfaces.
