Fine-L-Kote LED2 Silicone Coating
- Chemical Family
- Silicones
Fine-L-Kote LED2 Silicone Coating is designed and formulated specifically for light emitting diode applications that require a completely transparent coating to provide a tough, extremely flexible protective coating. Fine-L-Kote™ LED2 offers the greatest flexibility for extreme temperatures on the flex and rigid circuitry found in LED displays, as well as an outstanding nonstick surface for soil repellency. Cured coatings are hydrolytically stable and retain their physical electrical properties even after being exposed to high temperatures and humidity without interfering with light wavelength or intensity. The Fine-L-Kote™ LED2 will not put any strain on delicate circuit components.

- Environmental Data
CFC, HCFC, CL. SOLV., VOC, and HFC numbers shown are the content by weight. Ozone depletion potential (ODP) is determined in accordance with the Montreal Protocol and U.S. Clean Air Act of 1990. The ODP of this product is 0.0. It is the sum of the ODP of the substances that may contribute to the depletion of stratospheric ozone, based upon the weight of each substance in the product's formulation. Environmental Policy Techspray® is committed to developing products to ensure a safer and cleaner environment. We will continue to meet and sustain the regulations of all federal, state and local government agencies.
- Usage Instruction
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).
