Handling and Processing Instructions
General Requirements
 |
Light Sensitive Material - Avoid Unintentional
Exposure to Light.
|
 |
Process at 70° C - Must
be Thoroughly Mixed Before Processing. Store at 70°
F
to Maintain Mixture Homogeneity. If Separation Occurs (white flakes in
mixture), Heat to 70° C and Tumble to Mix.
|
 |
Material is Sensitive to Freons - Do Not Expose
Cured Coatings to Freons.
|
Health Information
 |
Mixture is Irritant.
|
 |
Avoid Eye and Skin Contact - Wear Protective
Clothing.
|
Shelf Life
 |
One year unless exposed to heat or light.
|
Equipment Requirements
 |
UV Light Source - Fusion UV Curing Systems
(301/251-0300) Model F300 or Equivalent.
|
 |
Protected Enclosure for UV Exposures.
|
 |
Spray Gun - BINKS Model 115 with 78S tip and 8 oz
fluid cup or Equivalent. Propel with Nitrogen.
|
 |
Clean Bench or Fume Hood to Control Dust and Fumes.
|
 |
Antistatic Materials for Handling Electronic
Components.
|
Spray Coating Procedures
 |
Filter AT-924 Epoxy at 70°
C into Clean Spray Gun Reservoir.
|
 |
Surface Preparation - Surfaces to be Coated Must be
Contaminant Free. Clean with an Appropriate Solvent. Where Possible, Etching
or Abrading Surface Will Promote Adhesion.
|
 |
Spray Coating - Spray with Epoxy at 70°
C with 30 psi Nitrogen. Where Possible, Spray onto Warm Substrate for Best
Results. Avoid Exposure of Coated Substrate to Dust or Other Contaminants
Prior to UV Cure.
|
 |
UV Cure - Expose to High Intensity UV Light Source
for 60 Seconds. Light Must Reach into All Coated Areas - Rotate Substrate or
Expose in a Reflective Enclosure.
|
 |
Postcure - Expose UV Cured Coating at 70°
C for 2-4 Hours in a Clean Oven to Complete Cure. May be postcured at 125°
C for higher temperature applications.
