White Usage Instructions Technical and Application Assistance For industrial use only. Read SDS carefully prior to use. Chemtronics provides a technical hotline to answer your technical and application related questions. Cleaning: For best adhesion, clean the board with a The toll free number is: 1-800-TECH-401. Chemtronics Electro-Wash cleaner in order to remove any surface contamination which may prevent adequate material Note: contact. This information is believed to be accurate. It is intended for professional end users having the skills to evaluate and use the Application: The overcoat material is dispensed throughout data properly. CHEMTRONICS does not guarantee the the CircuitWorks Overcoat Pen. Squeezing the pen body accuracy of the data and assumes no liability in connection with damages incurred while using it. while pressing down on the surface will allow the material to flow. Thinning: The overcoat material has been optimized for the CircuitWorks Overcoat Pen and thinning is not normally necessary. However, propyl acetate may be added with thorough mixing to make slight adjustments for ease of application in the bulk form. Drying: The overcoat material dries in 5 to 10 minutes at room temperature. A heat cure of 5 - 10 minutes at 200F (93C) is recommended for more demanding applications and for enhancing the chemical resistance. Clean-up / Removal: The overcoat material can be removed from surfaces using acetone. 8125 Cobb Center Drive, Kennesaw, GA 30152 1-770-424-4888 www.chemtronics.com 1-770-424-4888 www.chemtronics.com
