Swelling test epoxy only

  • The film made on February 4 was cut into pieces, weighed and measured for thickness, then placed in water until the next lab period
  • Measurements were as follows:
Section Initial thickness (mm) Initial weight (g) Final thickness (mm) Final weight (g) % difference in thickness % difference in weights
1 2,17 2,22551
2 1,78 2,23953
