Long term protection against storage corrosion? (Pennsylvania)  

++

Recently I heard from a vendor that to prevent corrosion and rust that the US Mint uses a packaging material called Corrosion Intercept. Allegedly it can maintain any metals surface corrosion free for up to 10 years without desiccant oils or VCI's. I am looking for a way to preserve metal lead frames. Has anyone tried deep storage in this material? It sounds to good to be true?

Hi, Richard. I'm sure it works in principal. But absolutely everything has disadvantages. Until their competition sees the ads and begins testing and comparing and weighing in, you probably won't know what those disadvantages are.

How are you pronouncing "lead" in "lead frames"? If it rhymes with "bead", what are they plated with? (If it rhymes with "dead", I don't foresee much corrosion anyhow).
