| Chemical Resistance Classification |
| E = Excellent
- 30 Days of constant Exposure cause no damage. Plastics may
even tolerate for years |
| G = Good - Little or no
damage after 30 days of constant exposure to the reagent |
| F = Fair - Some effect
after 7 days of constant exposure to the reagent like crazing,
cracking, loss of strength or discoloration |
| N = Not Recomended - Not
for Continous use. Immediate damage may occur |
