Ultra-Illumina™ 3502
- Chemical Family
- Acrylics & Acrylates
Ultra-Illumina™ 3502 is a UL-compliant, 100% solids UV light curable conformal coating for PCB assembly. It is suitable for use in high-volume spray systems, does not clog valves due to the absence of volatiles, and is environmentally friendly. When fully cured, Incure 3502 forms a hard and resilient protective coating with a thickness of 30 to 150 microns that functions as a moisture barrier with excellent adhesion in harsh environments. The presence of permanent fluorescence allows for quick in-process and quality inspection of coating coverage. Moisture-curing coated components in shadowed areas take 72 hours.

- Shelf Life Storage
Shelf−Life of this unopened product is a minimum of ONE (1) year from date of manufacture. Avoid direct exposure of bottle to visible light at all times. Containers should remained covered when not in use. Product should be stored in a dark cool place of 10°C to 32°C. Transfer of product into other packages void all warranties. Users should ensure all bonding surfaces are free of grease, mold release, or any contaminants, as bonding performance will be compromised. All tests for cured bonds should be carried out at ambient temperature. For safe handling of this product, please read Material Safety Data−sheet (MSDS) prior to use. Organic solvents, such as IPA, may be used to wipe away uncured material from surfaces.

- Note (Uncured Properties)
2. ISTM - refers to Incure Standard Test Method. 3. ASTM 638 Young's Modulus test speed @5mm/min for rigid and semi-rigid materials, at 50mm/min for non-rigid materials, unless otherwise specified.
- Certifications and Compliance
- UL Compliant
- EtO And Gamma Sterilization
All Incure medical products are formulated to subject to standard sterilization methods, such as EtO and Gamma Radiation of 25 to 50 kGrays (cumulative). Enhanced moisture and thermal resistance of this product show excellent adhesion and bonding strength after one cycle of steam auto-clave test. Depending on bond design and structure of the application, users should test specific assemblies after subjecting them to sterilization. Consult Incure Support Team for assistance, if your devices are subjected to more than one sterilization cycles.
