Smooth-on 300 Results

The liquid plastic is very nice to work with. 


  • 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



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