LUISIO W30 is a boron free stop off paint for gas carburizing. It provides good protection properties against carbon depths up to max. 1,5 mm. The stop off paint is delivered ready for painting. For dipping or spraying we recommend LUISO W302.



Before using, LUISO W30 should be stired up shortly and then applied with a paint brush. One layer is sufficiant. To avoid evaporation the cans should be sealed hermetically after use. To restore normal viscositiy the stop off paint can be diluted by adding up to 2 % water. No special thinners are necessary.
The dry off time for LUISO W30 is 30 minutes. The heat treatment with LUISO W30 should not exceed temperatures above 1050 °C. After heat treatment LUISO W30 residues may be removed by using alkaline water or steel brush.



LUISO W30 to be delivered in PP-cans of 1, 5 or 10 kg.



LUISO W30 is sensitive to frost. Storage at room temperature is recommended. Opened cans should be closed after use. Storage time should not exceed 12 months.
