L (7/18) Page 2 of 2 CircuitWorksâ Overcoat Pen Product# CW3300C, CW3300G, CW3300BLACK, CW3300WHITE Availability Compatibility CircuitWorks Overcoat Pen material is generally compatible with materials used in printed circuit board fabrication. As with any adhesive/sealant, compatibility with substrate should be determined on a non-critical area prior to use. Usage Instructions CW3300C CW3300G CW3300B CW3300BLACK CW3300WHITE 4.9g / 0.16 oz. Clear 4.9g / 0.16 oz. Green 4.9g / 0.16 oz. Blue 4.9g / 0.16 oz. Black 4.9g / 0.16 oz. White 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. The toll free number is: 1-800-TECH-401. Cleaning: For best adhesion, clean the board with a Chemtronics Electro-Wash cleaner in order to remove any surface contamination which may prevent adequate material contact. 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. Application: The overcoat material is dispensed throughout the CircuitWorks Overcoat Pen. Squeezing the pen body 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 200°F (93°C) 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 Ÿ 1-770-424-4888 Ÿ www.chemtronics.com 1-770-424-4888 Ÿ www.chemtronics.com
