Key Substrates PET substrates
LOCTITE ECI 8001 E&C is a Positive Temperature Coefficient
(PTC) screen printable ink designed for applications where self
regulating heaters are required. This material is formulated to
rapidly heat to a specific threshold temperature and then
maintain constant temperature for the device.

TYPICAL CURING PERFORMANCE
Recommended Drying Cycle
10 minutes @ 120°C
LOCTITE ECI 8001 E&C can be dried using forced air or infrared
systems. Higher temperatures for longer time exposure will improve
the performance. Care should be taken with infrared. Too much
energy can destroy the coating.
Design drying rates for the maximum the substrate and production
speeds can tolerate.
The above drying profile is a guideline recommendation. Conditions
(time and temperature) may vary based on customers' experience
and their application requirements, as well as customer drying
equipment, oven loading and actual oven temperatures.
