Alumina-Silica Insulation Type AX Moldable
GENERAL INFORMATION
ZIRCAR
Alumina-Silica Insulation Type AX Moldable is a putty like material consisting of
alumina-silica fibers dispersed in a sticky water based refractory binder. It
exhibits excellent adhesion and insulation properties. AX Moldable is characterized
by its high strength, low shrinkage, and resistance to most molten aluminum alloys up to
1260°C(2300°F).
AX Moldable is useful to obtain a hard surface coating, bond alumina-silica fiber based insulation products to themselves and to form complex shapes. It is readily shaped into complex forms using molds & hand building techniques or applied to surfaces.
When
applying a coating or building monolithic structures, AX Moldable is best
applied in thin layers (up to 1/2" thick) and at room temperature. This
ensures maximum adhesion and accommodates drying shrinkage. Once placed, the
material should be allowed to dry prior to applying the next layer. It can
be air dry or forced dried with an electric heating device or low gas flame.
Alumina-Silica Insulation Type AX Moldable can be used to make a cement suitable to bond fibrous insulations such as Alumina-Silica Insulation Type ECO-1200B to itself or other similar materials. This tenacious cement is easily prepared by combining AX Moldable and hot water.
