THREADLOCKERS, ADHESIVES, SEALANTS AND LUBRICANTS 00-14 FUNCTION DESIGNATION DESCRIPTION INSTANT ADHESIVES Loctite 401 Colour: colourless Cyanoacrylate instant adhesive suitable for bonding a wide range of acidic and porous ma- terials including, ceramics, wood, rubber and plastic (excluding polyolefin). Curing takes place in a few seconds as an effect of the condensed humidity present on the surfaces to be bonded, and is independent of environmental conditions. Loctite 495 Colour: colourless Cyanoacrylate instant adhesive suitable for bonding a rubber, plastics and metal in any com- bination. SILICONE SEALANTS Silastic 738 (Dow Corning) Colour:
milky white One-part silicone adhesive/sealant, ready for use. Cures on exposure to air to form a rubbery solid and obviates the need for conventional seals on flexible joints, filling gaps greater than 1 mm. Dirko Transparent Colour: transparent One-part silicone adhesive/sealant, shrinking, ready for use. Cures rapidly when exposed to humidity in the air to form a rubbery solid; resistant to high temperatures. POLYURETHANE SEALANTS Betaseal HV3 (Gurit Essex) Colour: black Polyurethane prepolymer based adhesive/sealant, high viscosity, suitable for permanent, high-strength flexible bonding. Slow curing, used for bonding glass to frames, wire mesh, metal plates, etc.
surfaces must be degreased with primer. RETAINING COMPOUNDS Loctite 601 Colour: fluorescent green Anaerobic, fast-curing, high-strength adhesive. Suitable for sealing and retaining cylindrical assemblies with gap clearances of up to 0.10 mm; used for retaining rotors, gears, bearings, pulleys, bushes etc. on shafts. Loctite 638 Colour: fluorescent green Anaerobic structural adhesive, quick-curing, very high strength; suitable for bonding cylin- drical parts in non-ferrous alloys. Loctite 648 Colour:
fluorescent green Anaerobic structural adhesive, quick-curing, high-strength; suitable for bonding cylindrical parts, permanent retention of threaded parts, sealing of refrigeration systems, retention of bearings, etc. Alternative to Loctite 601 in high-temperature applications. Loctite 986/AVX Colour: fluorescent red Anaerobic sealant/retaining compound for metal cylindrical parts. Slow-curing, high-strength, heat-resistant and resistant to chemical pressure. Parts must be first treated with an activator. LUBRICANTS Grease (NLGI 2 EP ASTM D217: 265/295) Multi-purpose Lithium grease used for lubrication of seals, to prevent oxidization and to fa- cilitate assembly operations.
Molikote (Dow Corning) Anti-wear compound, contains Molybdenum bisulphate, use neat or diluted with engine oil for assembly of main engine bearings. Vaseline Neutral pH compound used to protect battery terminals against oxidization and corrosion. Engine oil 10W - 30 Used to dilute Molikote anti-wear lubricant during assembly of main engine bearings.
