LUISO W33 is a fragrance-free and solvent-free stop off paint for gas carburizing. It provides good protection properties against carbon depths up to max. 3 mm max. The stop off paint is delivered ready for painting.
Before using LUISO W33 should be stired up shortly and then applied with a paint brush. The work pieces to be treated must be free of grease and dirt! One layer is sufficient. 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 W33 is 30 minutes. The heat treatment with LUISO W33 should not exceed temperatures above 970 °C.
After heat treatment LUISO W33 residues may be removed by shot-blasting or steel brushing. The paint is environment-friendly and therefore no special precautions are required.
