Fine-L-Kote UR Urethane Conformal Coating

1 of 6 products in this brand
Fine-L-Kote UR Urethane Conformal Coating is a Techspray® product that comes in a variety of coating formulas to meet field and engineering requirements. Specifications are generally determined by the type of protection required. Thermal, moisture, and static resistance, for example. Coatings contain Opti/Scan to allow quality control inspection of coating coverage and evenness on a PCB. When a coated board is exposed to a common, low-cost UV (short-wave black) light, the coated areas glow. The thicker the coating, the brighter the glow.

Usage Instructions

Spray Application: Apply top to bottom, allowing coating to flow evenly around components. Rotate PCB 90º 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 coating process. After application, cured Fine-L-KoteTM may be removed using Techspray Conformal Coating Removal Pen (2510-N or 2510-P).
