Smooth-on 300 Results

The liquid plastic is very nice to work with. 

Advantages:

• No harsh fumes which give you a headache
• Cures in 10 minutes opposed to overnight
• It's not as rigid as the casting resin so it doesn't crack when it's pounded on something

Disadvantages:

• It's not as thick so the pcb doesn't float on the resin which can lead to the pcb not being completely encapsulated.
