LUISO W34 is a copper-free stop off paint for gas carburising. It provides good protection properties against carbon depths up to max. 3,5 mm. The stop off paint is delivered ready for painting.
Before using, LUISO W34 should be stirred up shortly and then applied with a paint brush. One layer is sufficient. To avoid evaporation the cans should be sealed hermetically after use. To restore normal viscosity the stop off paint can be diluted by adding up to 2 % water. No special thinners are necessary. The dry off time for LUISO W34 is 30 minutes. Unwanted paste residues may be removed easily with water. The heat treatment with LUISO W34 should not exceed temperatures above 1050 °C. After heat treatment the LUISO W34 residues can be removed by shot-blasting or steel brushing.
LUISO W34 to be delivered in PP-cans of 1, 5 or 10 kg.
LUISO W34 is sensitive to frost. Storage at room temperature is recommended. Opened cans should be closed after use. Storage time should not exceed 12 months.
