  • Best Practices for Dow 93-006-6 Aerospace Sealant

    *See Terms of Use Below

    1. Surface Preparation

      DOW CORNING 93-006 Aerospace Sealant adheres well to primed surfaces of most materials used in the aerospace and aircraft industries. Typical materials include glass, cured silicone rubber, cork, phenolic, polyester, epoxy, silicone resin laminates and most metals including stainless steel, titanium and aluminum. It may not adhere well to polyethylene or certain plastics and organic materials (including rubber), which bleed or exude plasticisers. Stronger and more uniform bonds are obtained by preparing metal and plastic surfaces with DOW CORNING® 1200 Primer. For best results: Clean the surface with a chlorinated solvent (see Handling Precautions) and a slightly abrasive pad or a coarse lint-free cloth.

      Rinse cleaned surface with acetone or methyl ethyl ketone.

      Apply a thin coat of primer by dipping, brushing or spraying.

      Allow the primer to dry for at least 1 hour, according to relative humidity.

      Silicone rubber surfaces should not normally be primed, but only roughened slightly with abrasive paper and rinsed with acetone.

    2. Application

      The catalysed material can be cast, troweled or air injected with standard equipment.

    3. Mixing

      The catalyst is added in a ratio of 10 parts of base to 1 part catalyst by weight. For best results the base should be thoroughly de-aired in standard vacuum equipment for 2 hours at greater than 650mm of mercury vacuum. The catalyst may then be added to the base in an air free mixer, such as a Semco® Pressure Mixer, model S1350 or S1378. Hand mixing may also be used if, after mixing, the product is deaired in vacuum for about 30 minutes.

    4. Curing

      When using 1 catalyst, DOW CORNING 93-006 Aerospace Sealant will have a working time of 1 hour with a cure time of 10 hours. However if 6 catalyst is used, the working time will be 6 hours and the cure time 48 hours. With either catalyst, DOW CORNING 93-006 Aerospace Sealant will achieve optimum physical properties in 7 days.
