Tasks for March 18
Preparation of epoxy films with JA-230
New films were prepared containing an alternative amine
The samples were stirred using an electromagnetic stirrer, then put on a hot plate at 60°C to store for a further 15 min and then poured into an aluminum dish to sit overnight before curing.
Preparation of new samples for adhesive strength test
A new adhesive test is to be carried out using zinc ring nails. Because of previous variations with amount of weight required to detach the nails from the metal plate, more trials will be done per epoxy type.
The epoxy mixture used to glue the nails contained epoxy and JA-400 in the following quantities:
Same procedure as with films was followed to mix the chemicals. (Stirred in electromagnetic stirrer, placed on hot plate at 60°C for 15 min)
