Temporary adhesive.

MB600 adhesive provides a cost-effective alternative to the deficiencies of currently used temporary adhesives. The adhesive is a single component, storage-stable, inorganic compound that features heat resistance and good adhesion to metals, ceramics, glass, most plastics and rubbers. It cures readily at ambient and more quickly at moderately elevated temperatures. It is completely odorless, non-toxic and non-flammable. The cured adhesive is water-soluble and does not leave any undesirable contaminants on the previously bonded surfaces. The aqueous liquid exhibits thermal stability up to 1500-deg F, and is a good electrical insulator. Additives are available for specific uses where partial or complete insolubility to water is desired. Master Bond Inc, Hackensack, NJ. http://www.1rs.com/011df-632

Acrylic fastener. The Microspheres line of water-based microencapsulated acrylic adhesives are designed to be factory pre-applied to threaded fasteners. The room-temperature curing material remains inert until the shearing action of engagement to a mating part causes some of the micro capsules to break, allowing the adhesive to cure. The adhesives are a low-cost, earth-friendly alternative for many of the existing solvent-based dry powder materials and slurries. ND Industries, Inc, Clawson, MI.

Ceramic adhesive. Ceramabond 685, a high-temperature ceramic adhesive, is used to bond ceramic gasketing materials to galvanized steel ductwork used in exhaust flue applications to 1850° F. The adhesive is a single component, dispensable, silica-based system that bonds tenaciously to ceramic and galvanized metal substrates. The fast-setting, thixotropic paste contains no asbestos or volatile organic compounds. Aremco Products, Inc, Valley Cottage, NY. http://www.1rs.com/011df-634

Abrasion/chemical resistant epoxies. Titanium Putty is an advanced precision-machinable, titanium-reinforced epoxy for making repairs to machinery and equipment. Its durable formulation yields high compressive strength and achieves functional cure in four hours. Brushable Ceramic is a low-viscosity, alumina-filled, brushable epoxy compound that, when applied in a 15-20 mil coating, provides a smooth, protective barrier against wear, abrasion, corrosion, erosion and chemical attack.

Lead-free paste. CR39 solder paste is designed to solder numerous metal finishes without requiring nitrogen during reflow. The paste leaves a minimal, clear, pale residue after reflow using a wide thermal profile. This product, which reflows in air, meets the Bellcore and IPC standards for high-reliability, no-clean pastes and is good for rapid printing. CR39 offers good open time and tack life, greatly extended abandon times, good slump resistance and soldering activity. Multicore Solders Inc, Richardson, TX. http://www.1rs.com/011df-635
