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.
A reinforced version with higher scratch and abrasion resistance is also available. Maximum continuous use temperature is 290°C (550°F).
What is Teflon
Teflon is DuPont's registered trademark for its non-stick coatings. Teflon coatings are specially formulated finishes that are based on PTFE, PFA, FEP, and ETFE fluorocarbon resins. Teflon-S is a related family of fluorocarbon coatings containing binding resins which provide increased hardness, abrasion resistance, and other desirable properties.
