Rust and Corrosion Proofers: Seal n Peel Unituff Products

seal n peel

Formerly known as Seal’n’Peel 452, Unituff 452 and Unituff OGS (specially made for stainless steel) has been a time-proven anti-rust and anti-corrosion coating since 1973, for use as a long-term rust and corrosion preventative membrane coating. Seal n peel Unituff 452 is excellent for the shipping and storage of parts and equipment, operational use, and even mothballing. As a polyvinyl polymer, it is easy to use, easy to apply, and easy to remove through peeling off by hand.

Unituff 452 and Unituff OGS have proven to extremely resist any manner of water seepage, rust creep, moisture creep, salt water, salt spray, and even humidity, making both anti-rust coatings effective for the oil and gas industry (where it is being used extensively in Australia), marine, industrial, commercial, operational, and offshore rust prevention applications. The long-term protection applies to all types of ferrous and non-ferrous metals and alloys exposed to any harsh acidity, chemicals, and harsh environments.

Advantages of Using Unituff

  • It extends tool, parts, and equipment life for all operations involving metalworks.
  • Provides excellent outdoor protection against all types of extreme weather and changes in temperatures.
  • Does not need any chemicals, oils, or removers when the membrane coating needs to be peeled off and removed. No cleaning after is necessary.
  • Allows protected metals to be handled since there is no oily residue.
  • No surface preparation needed as Unituff 452 Seal’n’Peel will adhere to any metal surface, even metals that are pre-rusted.

  • The protective coating can also prevent rust transfer between dissimilar metals.
  • Thermally stable and will not alter, melt, or chip off over broad changes of temperatures.
  • Easily peeled off by hand.
