PL37 Coating for Protecting Materials Against Nitriding

A 2-part air dry tin rich lacquer used as a stopping off medium during the nitriding process. Originally developed by Rolls Royce in their own labs and made under licence by Acheson Colloids, (where it was known as ANL – Anti Nitriding Lacquer). This material is now made by Indestructible as one of our specialist product ranges. Competitive to Degussa WSN 100 and Acheson’s Nitrostop N4 which contains xylene. Should not be used near copper parts, as tin melts into it which creates bronze.
