Casson Model over 0.4- 30 sec-1                                     250 to 700

 

TYPICAL CURING PERFORMANCE                                             

Recommended conditions for curing are exposure to heat above 100°C (typically 120~150 secs @ 150°C). Rate of cure and final strength will depend on the residence time at the cure temperature.

Direction for use                                                                

1. After storage in a refrigerator the adhesive must be allowed to equilibrate to room temperature before use, typically 12 hours.

2. Avoid cross contamination with other epoxy or acrylic adhesives by ensuring dispense nozzels, adapters etc. are thoroughly cleaned.

3. The quantity of adhesive dispensed will depend on the dispense pressure, time, nozzle size and temperature.

4. These parameters will vary depending on the type of dispensing system use and should be optimised accordingly.

5. Bath temperature should ideally be controlled at a value between 25°C-30°C, 50%RH for optimum results. Under these conditions product will remain dispensable in the tray for at least 2 to 3 days.

6. Uncured adhesive can be cleaned from the board with isopropanol, MEK or glycol ether blends such as Prozon.

 

Storage                                                                          

Store product in the unopened container in a dry location. Storage information may be indicated on the product container labeling. Products shall be maintained, optimally, at temperatures between 2°C to 8°C unless otherwise labeled, or, specified. Storage, at temperatures below 2°C, or, greater than 8°C, is not recommended. Temperatures below 2°C and above 8°C can adversely affect product properties.
