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
  1. For industrial use only. Read SDS carefully prior to use.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. Clean-up / Removal - The overcoat material can be removed from surfaces using acetone.
