| | Aug 30, 2013 — HiE-Coat™ 840-C, a jet-black, water-based, ceramic coating now produced by Aremco Products, Inc., demonstrates an emissivity greater than 0.90 at temperatures to 2500°F. The emissivity of a material can range from 0.00 to 1.00; a high emissivity material will absorb (rather than reflect or transmit) and very effectively re-radiate infrared energy. High temperature combustion chambers, ovens and furnaces constructed using high emissivity coatings are more energy efficient and distribute heat more uniformly.
HiE-Coat ™ 840-C is applied easily to ceramic and refractory surfaces using a sponge brush, roller or conventional spray equipment. The coverage rate is approximately 500 ft 2 /gallon based a two mil dry film thickness. Curing is accomplished in operation or by heating for 1-2 hours at 200°F.
HiE-Coat ™ 840-C is a user- and environmentally-friendly product. It is odorless, water-soluble, and contains no volatile organic compounds. It will not outgas upon curing or during operation, a particularly important feature for high temperature systems used in the automotive, electronics and aerospace industries.
HiE-Coat ™ 840-C is one of a series of coatings used to coat various refractory and metal substrates to improve thermal efficiency to 2500°F. Please contact Aremco's Technical Sales Department for more information about the HiE-Coat ™ series of products. | |
