Usage Instructions For industrial use only. Read SDS carefully prior to use. Before applying Konform AR conformal coatings, clean circuit boards to remove contamination and allow to dry. Cleaning may be performed with Chemtronics Flux-Off products. SPRAY APPLICATION: Apply top to bottom, allowing coating to flow evenly around components. Rotate PCB 90° and repeat application. Rotate and apply coating two additional times, then allow board to cure. If additional thickness is desired, apply additional coatings. When using liquid spray with automatic dispensing equipment, adjustments may be required in application rate and viscosity. Technical and Application Assistance Chemtronics provides a technical hotline to answer your technical and application related questions. The toll free number is: 1-800-TECH-401. Note: This information is believed to be accurate. It is intended for professional end users having the skills to evaluate and use the data properly. CHEMTRONICS does not guarantee the accuracy of the data and assumes no liability in connection with damages incurred while using it. DIP APPLICATION: Using automatic equipment or hand immersion technique, slowly immerse PCB into the coating and remove slowly. Use an average rate of approximately 1 foot per minute. After allowing the board to cure, process may be repeated to achieve desired thickness. BRUSH APPLICATIONS: Evenly apply coating to areas desired at thickness required. Allow time for curing before reapplying to achieve a thick coating. Use Chemask to protect components during conformal coating process. REMOVAL: After application, cured Konform AR may be removed by soaking in Chemtronics Electro-Wash Two Step. 8125 Cobb Center Drive, Kennesaw, GA 30152  1-770-424-4888  www.chemtronics.com 1-770-424-4888  www.chemtronics.com
