PYRO-PAINTâ„¢ 634-ALP New High Temp Refractory Coating

Published on 2010-01-15. Author : SpecialChem

Pyro-Paint™ 634-ALP, a new high temperature ceramic coating manufactured by Aremco Products, Inc., is now used to insulate and seal dense refractory brick used in high temperature kilns and furnaces to 3200 °F (1760 °C).

Pyro-Paint™ 634-ALP is a new high temperature, ceramic-based sealant used to fill the micro-porosity in dense refractory brick to improve the reliability of the brick and protect the metal shell from corrosion. Pyro-Painttm 634-ALP is a single part, water-dispersible, phosphate-bonded, alumina-filled system. It is an inert, chemically resistant, inorganic material that will not outgas or decompose in high temperature corrosive applications to 3200 °F (1760 °C).

Pyro-Paint™ 634-ALP is applied easily by brush, dip, or pneumatic spray equipment. Upon application it can be cured in-situ and ramped rapidly to elevated temperatures. A full cure is achieved after exposure for 1-2 hours at 700 °F.

Pyro-Paint™ 634-ALP further sinters and strengthens as it is exposed to temperatures above 1000 °F.

Pyro-Paint™ 634-ALP is available from stock in pint, quart, gallon and five-gallon drums.
