DuPont™ Deep Freeze™ with Teflon® Fluoropolymer
Sometimes, corrosion is so severe that parts cold weld and a typical penetrant will not work; this is when Deep Freeze should be used. DuPont® Deep Freeze chills metal down to -40° F causing micro-fractures in the rust. This extreme subzero cooling is critical to effectiveness of this product. Penetrating oils with Teflon® fluoropolymer then migrate deep into the part to break down rust and loosen the part.
