Alumina Adhesives

1650°C – 1850°C - Resbond^® 901 et 3901

Resbond^® 901 and 3901 Ceramic Fibre Adhesives and Coatings are high purity, Alumina Oxide based, Ceramic Composite that combines the refractory properties of Alumina with ceramic fibre reinforcement. No organics. No solvents. No VOC's. No out gassing.

Provides excellent resistance to oxidizing and reducing atmospheres, molten non-ferrous metals, steam, most chemicals and solvents.

Packaged in a ready to use, rich, creamy paint form. Just re- mix and apply. It is easily applied by brushing, spraying or dipping and cures at room temperature to form a hard surface coating. Use as an adhesive for bonding porous ceramics, as a coating for flame, oxidation, corrosion and erosion resistance and as a chemical barrier against diffusion and wetting in high temperature processing.

Resbond^® 901 and 3901UHT are creamy adhesives, 901A and 3901A are liquid hardener binders. Their common physical characteristics are listed below, their continuous use temperatures are:

• 1650°C for Resbond^® 901 and 901A binder,
• 1850°C for Resbond^® 3901 and 3901A binder, called "UHT".

901A Hardner

Rescor^® 901A Ceramic Hardener is a clear liquid which penetrates the surface of porous ceramics to form a strong ceramic bond and harden the surface. No organics. No solvents. Just brush on and let dry. Use 901A to prime surfaces before bonding and extend the life and wear resistance of insulation materials. Can be applied directly to marinate, calcium silicate, rock wool, mineral wool and ceramic fibre insulation. Hardens and extends the life and wear resistance of all porous. Melting point is 1760°C. Density is 10 pounds/gallon. Clean tools or containers with water.

3901A Hardner

Rescor^® 3901A is a mineral liquid that hardens and processes papers and ceramics that must withstand very high temperatures. It increases the mechanical strength of ceramics as well as their resistance to abrasion and flame. It limits the permeability to gases. As an impregnating product, it will be extended with deionized pure water in equal parts by volume. It will serve as a diluent for Resbond^® 3901 Adhesive.

1790°C - Resbond^® 903HP

Resbond^® 903HP is an ultra-high temperature, Alumina Adhesive. Developed for high strength bonding of any combination of dense non-porous ceramics, glass and or non-reactive metals. 903HP is a smooth, creamy paste that can be brushed, trowelled or sprayed on. Just re-mix and apply. Handling strength is obtained, after an initial cure at 120°C. A complete cure occurs in 1 hour at 315°C - 370°C. Resbond^® 903HP is usable to 1790°C continuously. It has excellent resistant to liquid metals, oxidizing and reducing atmospheres, most chemicals and solvents. 903HP has excellent electrical properties.

1650°C - Resbond^® 908

Resbond^® 908 is a new, High Purity, Alumina based adhesive incorporates a unique, catalytic curing system. Just mix the adhesive and its activator to form a readily dispensable, smooth, creamy paste. It will not clog delicate dispensing needles and is suitable for any application requiring micro drops or several ounces of material. 908 has excellent electrical resistance, moisture resistance and thermal conductivity. Resbond^® 908 will become water insoluble after use (or post cure) at temperatures of 120°C – 150°C.

1600°C - Resbond^® 920

Resbond^® 920 is ideal for use in applications where a combination of high electrical resistance and good thermal conductivity is required. It’s based on conductive Alumina ceramic and should be used whenever rapid dissipation of heat is required. It offers excellent electrical, chemical and solvent resistance. Resbond^® 920 is easy to use, just mix, apply and cure at room temperature. Cures can be accelerated with mild heat. 920 is easily incorporated into many production processes.

1650°C - Resbond^® 989

Resbond^® 989 is a one component high purity, 1650°C Alumina based, general purpose adhesive. It has a smooth creamy consistency and cures at room temperature to form strong bonds to ceramics, graphite, metals and glass. Resbond^® 989 is resistant to oxidation, electricity, molten metals, most chemicals and solvents. Easy to use, just apply and air dry. Curing may be accelerated with mild heat.

1650°C - Resbond^® 989FS

New, Resbond^® 989 Fast Set is specially formulated for applications requiring a fast setting, single component, alumina adhesive. Now, a free-flowing formulation that is ideal for use in automatic dispensing equipment. It is precisely dispensed through fine needles without clogging or mess. Resbond^® 989FS cures at room temperature or in 5 minutes at 90°C. It is the ideal choice for high speed production applications where automation is required.

1650°C - Resbond^® 989F

The Alumina used to formulate Resbond^® 989F particle size has been reduced to 600 nms. 989F combines this ultra-fine Alumina with special high temperature colloidal ceramic binders to create an adhesive ideal for a new generation of applications. 989F can be used in the finest dispensers. No clogs. No mess. It is an ideal choice for high temperature production applications. Now, there are no limits to applications requiring a high temperature alumina adhesive and the ability to bond super fine electric components, bundles of fibre optics filaments, cable end seals, components with tight tolerances.

1540°C - Resbond^® 940HT

Resbond^® 940HT is specially formulated, ultra-high temperature Alumina adhesive that can be used continuously to 1540°C. Resistant to liquid metals, most chemicals and solvents, oxidizing and reducing atmospheres.
