HIGH TEMPERATURE CERAMIC COATINGS

 

Accumet Materials’ ceramic coatings are used for coating metals and ceramics in high temperature applications to 3400 ºF.  These materials are easy to use and contain no volatile organic compounds, are non-flammable and environmentally safe. 

 

• REFRACTOCOAT ALS is a single component aluminum oxide based ceramic coating exhibiting temperature resistance to 3000 ºF.  When fully cured the coating is bright white and produces an excellent heat reflecting surface. 

REFRACTOCOAT ALS can be applied to all ceramic surfaces and also to some metals by brushing, dipping or spraying.  Applications include moisture sealing of ceramics and high temperature insulation of electrical components.

 

• REFRACTOCOAT SIS is a single component fused silica based ceramic coating, which exhibits excellent thermal shock resistance because of its very low thermal coefficient  of expansion.  The coating can withstand temperatures up to 2500 ºF and can be applied by brushing, dipping or spraying.

REFRACTOCOAT SIS can seal porous ceramic surfaces and exhibits a bright white smooth surface after curing.  It is an excellent thermal insulator because it has very low thermal conductivity properties.  The coating resists temperature cycling and even direct flame impingement.

 

• REFRACTOCOAT MGS is a two component magnesium oxide based ceramic coating exhibiting temperature resistance to 3200 ºF.  This material exhibits a high thermal coefficient of expansion making it suitable for coating metals and high expansion ceramics used in high temperature applications.

REFRACTOCOAT MGS can be applied by brushing, dipping or sprayed when thinned.  This coating is also ideal for potting very small cavities or parts.
