7 Possible Reasons

  1. Incorrect ratio
  2. Incomplete mixing
  3. Cold working conditions
  4. Excess pigment or additives
  5. Contamination
  6. Insufficient curing time
  7. Using incompatible resin and hardener

Don't immediately add extra hardener to fix sticky resin.

Use the Fusion Resin Calculator for accurate measurements.

Try Fusion Vitro 2:1 for coating/art projects or Fusion Flex 3:1 for deep casting.
