The castable which sets the standards for performance, ease of application, and long life throughout its full range of applications is Resco's premium, abrasion/erosion-resistant castable, Rescobond AA-22S. Particularly effective in thin, metal-anchored and metal-reinforced linings, Rescobond AA-22S offers all the benefits of air setting. Because it readily bonds to other refractory surfaces it is ideal as a quick and easy patch -- a permanent patch -- for worn linings.

The Rescobond, family of castables are easy-to-mix castables which adhere permanently to all refractory surfaces with heat curing. This line of specialty products offers exceptional physical properties for all applications and can be used for patching or for a full lining.

RESCOBOND AA-22S	is a chemically bonded, erosion resistant, single component refractory material used primarily in thin lining applications to protect against severe abrasion. To prepare for use, mix the RESCOBOND AA-22S with water. RESCOBOND AA-22S is an air setting material. It can be used to patch other refractory linings.
RESCOBOND AA-22 BRUSH MIX	is a slurry material that's ideal for strengthening existing refractory lining surfaces. It can be applied to 1/4" thick providing increased refractory protection without a great loss of volume to your unit. At an application thickness of 1/4", one 65 pound pail will cover approximately 18 square feet. Its white, reflective, surface finish helps to reduce heat loss by reflecting heat back into the unit
RESCOBOND 3000	is a phosphate bonded, chemically setting refractory castable that is prepared for use by mixing with water. It develops a quick set, and can be heated shortly after installation to provide a fast "back on line" capability for your unit. In addition to its use as a primary lining, RESCOBOND 3000's chemical bonding system provides adherence to existing refractory, making it an effective patching material. RESCOBOND 3000 can be installed by vibration casting or hand-packing techniques.
RESCOBOND 3000A	is a phosphate bonded, chemically setting refractory castable that is non-wetting to molten aluminum. When mixed with water, it develops a quick set, and can be heated shortly after installation to provide a fast "back on line" capability for your unit. In addition to its use as a primary lining, RESCOBOND 3000A's chemical bonding system provides adherence to existing refractory, making it an effective patching material. RESCOBOND 3000A can be installed by vibration casting or hand-packing techniques.
RESCOBOND 3000G	is a single component phosphate bonded, chemically setting refractory gunning mix. It develops a quick set and can be heated shortly after installation to provide a fast "back on line" capability for your unit. It's chemical bonding system provides adherence to existing refractory, making it an effective patching material. RESCOBOND 3000G can be installed by gunning using conventional gunning equipment or hand-packing techniques.
RESOBOND 3000AG	is a single component phosphate bonded, chemically setting refractory gunning mix that is nonwetting to molten aluminum. It develops a quick set and can be heated shortly after installation to provide a fast "back on line" capability for your unit. It's chemical bonding system provides adherence to existing refractory, making it an effective patching material. RESCOBOND 3000G can be installed by gunning or hand-packing techniques.
RESCOBOND 90	is a phosphate bonded, high purity, 90% alumina refractory castable that is prepared for use by mixing with water. It develops a quick set, and can be heated shortly after installation to provide a fast "back on line" capability for your unit. In addition to its use as a primary lining, RESCOBOND 90's chemical bonding system provides adherence to existing refractory, making it an effective patching material. RESCOBOND 90 can be installed by vibration casting or hand-packing techniques.
RESCOBOND 90A	is a phosphate bonded, high purity, 90% alumina refractory castable that is non-wetting to molten aluminum. When mixed with water, it develops a quick set, and can be heated shortly after installation to provide a fast "back on line" capability for your unit. In addition to its use as a primary lining, RESCOBOND 90A's chemical bonding system provides adherence to existing refractory, making it an effective patching material. RESCOBOND 90A can be installed by vibration casting or handpacking techniques.
22 CAULK	is shipped in ready-to-use caulking tubes and is applied with a caulking gun. 22 Caulk is used to fill cracks and joints in refractory linings.

The RESCOBOND family of products are phosphate-bonded, chemically setting refractory castables that are prepared for use by simply mixing with water. They develop a quick set and can be heated shortly after installation without a dryout schedule to provide a fast “back on line” capability for your application. RESCOBOND’s chemical bonding system provides adherence to existing refractory, making it a highly effective monolithic repair and continuous lining material.

Some of RESCOBOND’s unique properties are:
• Adheres immediately to refractory surfaces without additional anchoring
• Requires no curing period or dryout
• Non-hazardous single component product-just add water to the mixer
• Excellent physical properties for most industrial applications
• Excellent for precast shapes that require immediate usage
• Ideal for patching existing linings, or can be used for full linings
