Technical Details & Test Data
- Processing
Bring ZeoGlue‐HV to room temperature before use. Deposition must be carried out in dry environment.
Deposition
-
Typical dispensing by syringe (needle diameter > 0.1 mm)
-
Compatible surfaces are:
-
Glass
-
Stainless Steel and other metals (one‐side only e.g. metal to glass)
-
Plastics if compatible with UV curing
-
Curing
-
UV Curing is required
-
Suggested curing conditions are:
-
irradiance of 100mW/cm2 for > 120s with λ = 365 nm.
-
thermal post curing at 80°C for 30 minutes.
-
max irradiance: < 500mW/cm2.
-
max energy density: < 12J/cm2.
-
Curing must take place in glove box (< 10 ppm H2O).
-
Weight loss during curing: < 0.2 %.
-
-
- Cleaning
Typical solvent used for cleaning is Acetone or Acetic acid diluted at 5% in water.
- Barrier Properties: The Concept of Breakthrough Time
Barrier Properties Value unit WVTR (23°C 65% RH (300 μm) after Saturation*) < 0.1 g/m2 day Breakthrough Time (on 4 mm Line Width at 60 °C/90% RH) >1500(**) hour (*) In glass to glass configuration, on properly cured film. During breakthrough time the WVTR is theoretically zero and lower than the limit of detection.
(**) This can be considered equivalent to 2.5 years at 25 °C 30% RH. After this transient period the glue keeps working as state‐of‐art passive barrier, as shown with the reported WVTR after saturation.

Storage & Handling
- Storage
-
Shelf life of ZeoGlue‐HV is 6 months.
-
Storage conditions are temperature of +2 ‐ +5 °C and dry atmosphere.
-
ZeoGlue‐HV can be stored in a normal refrigerator provided that the original packaging is not open, or it is sealed in dry atmosphere.
-
In the event of exposure at temperature higher than 50°C, ZeoGlue must be discarded.
-
- Handling and Air Exposure
-
Barrier bag should be opened in glove box (< 10 ppm H2O).
-
Opening in air must be avoided.
-
In the event of air exposure, ZeoGlue‐HV must be discarded.
-
Before use, it must be left at room temperature for at least 2 hours; otherwise viscosity could be higher than the nominal value.
-
Uncured ZeoGlue‐HV can be maintained at room temperature for maximum 120 hours before using.
