Ambient: Dries to a tack-free state in roughly and reaches optimum properties in 30 days at room temperature.
The coating reaches a "tack-free" state in approximately . Full curing can be achieved through two primary paths: Ambient: 30 days at room temperature. Accelerated: 30 hours at 76°C or 20 hours at 88°C. Common Industry Applications humiseal 1a68
Typically applied at a thickness of 25 to 75 microns (1-3 mils). Storage and Maintenance Ambient: Dries to a tack-free state in roughly
HumiSeal 1A68 is engineered to meet rigorous industry standards while remaining easy to apply and inspect during manufacturing. Single-component Polyurethane Operating Temp Range -65°C to +125°C Dielectric Breakdown 7,500 Volts Recommended Thickness 25 – 75 microns Shelf Life 24 months from date of manufacture Compliance IPC-CC-830, RoHS (2002/95/EC), UL File E105698 Primary Features and Benefits Accelerated: 30 hours at 76°C or 20 hours at 88°C
