The Corrosion Block Anti Corrosion Grease can be described as a clean, clear, ultra-thin fluid, leaving a non-greasy atmospheric barrier which will help protect the base metal on interior surfaces. Corrosion Block leaves no gummy residue because it contains no wax, resin, tar, asphalt, silicone or Teflon.Superior anti-corrosion compoundKills corrosion in progressPrevents new corrosion cells from formingACTIVE for 12-18-months - non-dryingAn excellent penetrant and light lubricantThe Corrosion Block Anti Corrosion Grease can remove moisture. When it is combined with its excellent penetrating and strong dielectric properties, it has been known to have brought several electronics 'back from the dead' with just one application.The Corrosion Block removes the moisture from the corrosion by-product, then isolates the corrosion by-product from the electrical circuit. Corrosion Block can be used in many different electrical and electronic applications without fear of damage, and it won't harm any plastics or painted surfaces and is good for rubber, keeping it from cracking and drying out.
