There is no silicone, either as an ingredient or trace contaminant, in any of our Tap Magic cutting fluid formulas. This includes Tap Magic EP-Xtra®, Tap Magic Aluminum, Tap Magic ProTap, Tap Magic Formula 1 “Aqueous”, Tap Magic Eco-Oil, Tap Magic Xtra-Thick and Tap Magic Xtra-Foamy.
All Tap Magic products have a recommended shelf life of 5-8 years depending on storage conditions with the exception of Tap Magic Eco-Oil which has a recommended shelf life of 18 months.
Other factors, such as the propellant in our aerosol cans, may affect life of the product. Tap Magic may be used well beyond this timeframe but there may be a decrease in performance for protecting your tooling and workpieces.
