3608 - Protektor PolyCoat UV 5Ltrs

Product Description

Protektor PolyCoat UV is a high-performance photopolymer resin coating specifically engineered to protect PCBs from corrosion, oxidation, and harsh environmental conditions. It forms a durable, transparent film with excellent adhesion, superior mechanical properties, and chemical resistance.

The coating cures instantly when exposed to a medium-pressure mercury vapor UV lamp, delivering rapid line speeds and high productivity. With a viscosity of 21 seconds (Zahn Cup #4 at 25°C) and density of 1.13 g/cm³, the formulation is optimized for spray, dip, or roller application in industrial settings.

Key Benefits

• UV Curable: Rapid cure under UV light; improves throughput and reduces downtime.
• Superior Adhesion: Passes Cross Hatch Test, ensuring excellent bond with metals.
• Anti-Corrosion Protection: Provides long-term resistance to rust, oxidation, and moisture.
• High Clarity: Dries clear and does not interfere with visual inspection of underlying parts.
• Mechanical & Chemical Resistance: Withstands wear, abrasion, and chemical exposure.
• VOC-Compliant & Solvent-Free: Reduced environmental impact and safer workplace use.

Applications

• Protective coating for PCBs, metal tools, fixtures, sheet metals, and machined parts.
• Ideal for use in automotive, aerospace, industrial machinery, and precision electronics.
• Suitable for in-line UV cure systems or batch-curing environments.

Technical Specifications

Directions for Use

1. Surface Preparation
   • Ensure metal surface is clean, dry, and free from oil, dust, or oxidation.
   • Use an appropriate degreaser or solvent wipe to prepare surface.
2. Application Methods
   • Spray, dip, or roll uniformly over the surface.
   • Recommended wet film thickness: 30–50 microns.
3. UV Curing Process
   • Use medium pressure mercury vapor lamp (300 W/in; 3 kW total power).
   • Maintain 2-inch curing distance from lamp surface.
   • Pass substrate under lamp at >100 ft/min for optimal results.
4. Post-Cure Handling
   • Cured surface is ready for handling immediately.
   • Full chemical resistance may develop within 24 hours.

Precautions

• Store in a cool, dark, dry place away from sunlight and ignition sources.
• Avoid skin or eye contact. Use appropriate PPE during application.
• Do not use in confined spaces without adequate ventilation.
• Ensure UV safety shields are in place to protect operators during curing.
