Spray Application: Apply top to bottom, allowing coating to flow evenly around components. Repeat application 3 additional times from varying directions to prevent component shadowing. 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).

- Cure Profile
Accelerated Cure: 20 minutes @ 149°F / 65°C
Ambient Cure: 15 hours @ 74°F / 23°C (ambient temp)
Tack-Time (dry to touch): 3 minutes @ 74°F / 23°C (ambient temp)
Cure time depends on a number of factors, including the method and thickness of application. Dilution will also change the cure profile. 149°F / 65°C is recommended as the best accelerated temperature to optimize leveling, providing the smoothest possible finish. A faster cure may be achieved, but should be thoroughly tested first.

Packaging & Availability
- Thinning/Removal
Techspray® coatings can be thinned to meet production requirements using Conformal Coating Thinner (2105). Conformal Coating Remover (2510) is also available for rework and repair, although coating is often just burnt through in the soldering process for spot repairs. Techspray® coatings contain Opti/Scan to allow quality control inspection of coverage and evenness of the coating on a PCB. A coated board can passed under a standard, low-cost UV (black) light, and the coated areas glow. The brighter the glow, the thicker the coating.
