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
