BONDERITZTechnical Process Bulletin <br /> BONDERITE M-CR 1200S AERO <br /> CHROMATE COATING <br /> (KNOWN AS ALODINE 1200S) <br /> PROCESS: <br /> The complete process for the BONDERITE M-CR 12005 AERO (known as ALODINE 12005) treatment normally consists of <br /> the following steps: <br /> 1. Cleaning <br /> 2. Water rinsing <br /> 3. Deoxidizing (required for heavily oxidized surfaces) <br /> 4. Water rinse (required when deoxidizing is used) <br /> 5. Treating with the BONDERITE M-CR 12005 AERO (known as ALODINE 12005) processing solution <br /> 6. Water rinsing <br /> 7. Drying <br /> MATERIALS: <br /> 1. BONDERITE M-CR 12005 AERO (known as ALODINE 12005) <br /> 2. Nitric Acid <br /> 3. BONDERITE° (cleaner) <br /> 4. Testing Reagents and Apparatus <br /> EQUIPMENT RECOMMENDATION: <br /> Process tanks and housings should be fabricated from 300 series alloy stainless steel, such as 304L or 316L. The 316L <br /> being preferred for maximum tank life. In all cases approved welding techniques must be used. <br /> Brush Application: <br /> Acid-resistant (wood, rubber, stainless steel, or plastic) buckets, troughs, or other suitable containers are used to hold <br /> the diluted BONDERITE M-CR 1200S AERO (known as ALODINE 12005) coating chemical solution. Lead,glass, tin or <br /> galvanized iron should not be used. Storing the solution in mild steel containers will result in a slow decomposition of <br /> the solution. <br /> Ordinary spray equipment (satisfactory for short or infrequent application)will be attacked slowly by BONDERITE M-CR <br /> 12005 AERO (known as ALODINE 12005) coating chemical. This may be minimized by thoroughly flushing with water <br /> immediately after use. For continuous use, plastic or stainless steel cups and nozzles should be used in spray <br /> equipment. <br /> Henkel <br /> 2of8 <br />
