Rev. B (12/19) Page 1 of 2 UR Urethane Conformal Coating Product 2104 Product Description Techspray offers a variety of coating formulas to match field and engineering requirements. Specifications generally depend on the type of protection needed. E.g. thermal, moisture, and static resistance. Coatings contain Opti/Scan to allow quality control inspection of coverage and evenness of the coating on a PCB. A coated board can be passed under a standard, low-cost UV (short-wave black) light, and the coated areas glow. The brighter the glow, the thicker the coating.

Read MSDS carefully prior to use. Before TM applying Fine-L-Kote conformal coatings, clean circuit boards to remove contamination and allow to dry. Cleaning may be performed with Techspray G3, E-LINETM and Precision-V defluxers. 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. 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 Application: Evenly apply coating to areas desired at thickness required. Allow time for curing before reapplying to achieve a thick coating. Use WonderMASK to protect components during conformal TM coating process. After application, cured Fine-L-Kote may be removed using Techspray Conformal Coating Removal Pen (2510-N or 2510-P). 800-858-4043 www.techspray.com Rev.
