Dow Corning 730 Solvent Resistant Silicone Sealant

Dow Corning 730 Solvent Resistant Silicone Sealant

Repair your aircraft's fuel tank using Dow Corning 730 Solvent-Resistant Sealant Adhesive from SkyGeek. The powerful sealant adhesive can be used to repair minor cracks or gaps, forming a lasting bond that's resistant to the corrosive effects of aircraft fuel. The chemically-resistant properties of this aircraft sealant allow it to resist the swelling effects of fuels, oils and solvents, staying in place and providing a reliable seal. Ideal uses for this adhesive include integral fuel tank and fuel system repairs and other applications in which components experience long exposure to harsh chemicals and moisture. This sealant can also be used to create formed-in-place gaskets to be used in areas that do not accept ordinary seals. This one-component adhesive features a paste consistency and cures at room temperature and ambient humidity levels.

Dow Corning 730 Solvent-Resistant Sealant Adhesive from SkyGeek is the all-in-one formula you need to tackle all of your fuel tank repairs. The easy-to-use formula goes on using standard tools like a spatula or sealant gun. It hardens to a rubber-like consistency and is designed to withstand the rigors of flight, including excessive vibration. Unused portions store well and a cap is provided to prevent the sealant from hardening between uses. Dow Corning 730 Sealant Adhesive is priced competitively and quantity discounts may be available on qualifying orders.

  • Hardens into rubber with tensile strength around 300 pounds per square inch
  • Withstands vibration
  • Stores well; cures using ambient moisture

Dow Corning 730 Solvent Resistant Sealant is not recommended:

  • For continuous underwater immersion where adhesion or structural bonding is required
  • On concrete, brick, mortar or other masonry surfaces
  • On surfaces to be painted; paints do not adhere well to sealant (paint before applying sealant)
  • On materials such as impregnated woods or oil-based caulks that bleed oils
  • In totally confined areas; atmospheric moisture is required for cure on Teflon1-coated materials, polyethylene, polypropylene or methylmethacrylate Plexiglas2); sealant will not adhere well
  • On or near sensitive metals such as copper, brass, zinc, carbon steel, galvanized iron or magnesium; these metals may be corroded, especially in confined cure conditions, due to the acetic acid released during the cure
  • With solvents such as acetone or ketones
  • Features
    • Single-component, solvent-resistant fluorosilicone adhesive and sealant
    • Made for bonding and sealing applications in which resistance to swelling effects of chemicals is necessary
    • Can be used to assemble and repair fuel tanks and systems
    • Perfect for formed-in-place gaskets when ordinary seals are impossible
    • Ideal for bonding and sealing parts frequently exposed to fuels, solvents, oils, shock, vibration and moisture
    • When exposed to ambient moisture, cures at room temperature
    • Acetoxy cure system
    • Thixotropic, non-sag paste consistency
    • Easily applied
    • Cured product forms strong, flexible rubber
    • Excellent adhesion to a variety of substrates
    • Remains stable and flexible from -85 to 500 degrees Fahrenheit
    • Maintains properties when exposed to fuels, oils and solvents
