Silverstone (plastic)

From Wikipedia, the free encyclopedia

SilverStone is a non-stick plastic coating made by DuPont. Released in 1976, this three-coat (primer/midcoat/topcoat) fluoropolymer system formulated with PTFE and PFA produces a more durable finish than Teflon coating.

As of 1980 Dupont required that the pans carrying the brand be a heavier weight than others on the market. After the coating was applied the cookware was subsequently "baked" in a 700-800 degree oven to affix the coating.[1]

The process for creating Silverstone cookware begins by sandblasting the products which creates an uneven surface that encourages adherence. Then a primer layer of Teflon is sprayed on and after it is baked at high heat to "a secure mechanical grip."[2] Gizmodo reported in 2014 that one or two more additional layers were applied after the initial layer.[2]
