Eighth
Lab Task: continue developing prototype applicator
 
Equipment
for prototypes. Double roller dispenser.
Continue building prototypes
The epoxy is PSI-326, which comes in part A and part B, mixed 1-to-1.
There are several designs of adhesive markers/applicators being tested.
These include:
1. Pre-loaded porous sponges with part A and part B applied to the rocks.
2. An all-in-one syringe/mixer.
3. Pre-loaded breakable spheres or balloons, loaded with part A and part B.
4. A double roller to squeeze the Smart Glue disposable applicator/mixer.
The effect of temperatures near 0 degrees Celsius may make the epoxy difficult
to mix. Prepare a tray of iced seawater to test the prototypes in chilled
water. Chill the epoxy before applying to a rock.
At the suggestion of UCCRTS technician West, we have a supply of silicone
caulk to try underwater.
Draw a diagram of your applicator/marker. Ask Dr. Sichel to photograph it
for the record.
