Step-by-Step Application Guide for Techspray Fine-L-Kote AR

1. Surface Preparation

Before applying the coating, ensure the board surface is thoroughly cleaned to remove oil, grease, and flux residue using a compatible flux remover. Surface must be completely dry before proceeding.

2. Spraying Procedure

1. Shake the aerosol can thoroughly prior to use.
2. Position the PCB horizontally on a clean, flat surface.
3. Hold the spray can 4 to 6 inches away from the board surface.
4. Spray from top to bottom, applying a light initial topical coating.
5. Immediately apply a second, heavier coat across the board, allowing liquid to flow around components.
6. Pro Tip: Invert the can and spray briefly until only clear propellant is expelled to prevent nozzle clogging.

3. Drying and Curing Timeline

• Tack-Free Time: Approximately 15 minutes.
• Full Cure: 24 hours (depending on ambient temperature and relative humidity).

Rework, Repair, and Removal

Reworking boards coated with Techspray Fine-L-Kote AR is straightforward:

• Spot Repairs: The acrylic layer can be easily burned through during standard soldering repairs.
• Thinning: Adjust viscosity using Techspray Conformal Coating Thinner (2105).
• Complete Stripping: Use Conformal Coating Remover (2510) to fully remove the coating within 30 to 45 minutes.
