Protecting sensitive electronic assemblies from moisture, corrosion, and harsh chemical exposure demands advanced surface engineering. Fine-L-Kote 1700 Fluorinated Coating (Product# 23170, 23172, 23194, 23294, 23278) offers an exceptional low-surface-tension protective solution that forms a thin, lightweight, highly repellant film over printed circuit boards (PCBs).
What is Fine-L-Kote 1700 Fluorinated Coating?
Fine-L-Kote 1700 Fluorinated Coating is a specialized fluorinated polymer conformal coating formulated by Techspray. Utilizing a low global warming potential (GWP) hydrofluoroether (HFE) solvent carrier, it delivers both hydrophobic (water-repelling) and oleophobic (oil-repelling) properties. The ultra-low surface tension ensures superior wetting under fine-pitch SMT components and low-standoff clearances without requiring complex post-application curing.
Key Features and Benefits of Fine-L-Kote 1700 Fluorinated Coating
- Dual Repellency Protection: Repels water, hydrocarbons, silicones, and photoresist solutions to prevent wetting, stiction, and corrosion.
- Thermal Stability: Capable of withstanding continuous operational temperatures up to 175°C (347°F) for 24 hours while maintaining surface repellency.
- Superior Substrate Adhesion: Bonds effectively to metals, glass, ceramics, polymers, composites, and laminates.
- Rapid Air Drying: Fast drying time (30 to 120 seconds) accelerates production throughput without thermal curing steps.
- Eco-Friendly & Safe: Non-flammable, low toxicity, zero ozone depletion, RoHS compliant, and EPA VOC-exempt carrier solvent.
- High Flame Resistance: Meets UL94 V-0 standards for flammability safety.
Target Applications
The anti-migration and anti-wetting properties of Fine-L-Kote 1700 Fluorinated Coating make it an ideal choice across demanding technical fields:
- Displays and Control Interfaces: Protects delicate visual display units from moisture intrusion and environmental contaminants.
- Data Communications & Instrumentation: Shields high-frequency circuitry from corrosion and dielectric instability.
- Automotive & Marine Manufacturing: Defends electronic control modules against saltwater spray, corrosive vapors, and oil residues.
- Industrial Process Control: Ensures long-term reliability in harsh chemical or high-humidity plant environments.
Application Guidelines
1. Application Technique
Thanks to its low surface tension, this coating easily penetrates under tight, low-clearance SMT components. It can be applied via dip, spray, or brush techniques depending on production requirements.
2. Drying Process
The HFE solvent carrier evaporates rapidly at ambient temperatures, achieving a tack-free, repellant finish within 30 to 120 seconds without needing oven baking.
