Dow Corning 730 Solvent Resistant Sealant

Dow Corning 730 Solvent Resistant Sealant

If you're the type of person who like things fast and easy, check out this Dow Corning 730 solvent resistant sealant. It applies easily in a single step and cures quickly, even faster in a moist environment. In fact, make sure you act quickly, as once Dow Corning 730 RTV is squeezed from the tube onto your surface, you only have about 10 minutes before a thin skin begins to form. From there, it will become harder to work with. Within 24 hours, it is fully cured and solvent resistant.

In addition to its standard use on fuel tanks or lines, Dow Corning RTV 730 can be used for many other applications. This sealant can hold up when heavily exposed to solvents or fuel.
  • Hardens into rubber with tensile strength around 300 pounds per square inch
  • Withstands vibration
  • Stores well; cures using ambient moisture
Read the Dow Corning Silicone Sealant Brochure for more information.
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
