R that can be added to the fixer is dependant on the film and process conditions used In some processors the full amount of hardener cannot be used as the fix and wash times cannot be extended adequately In these circumstances we recommend starting with the minimum amount of hardener to have some effect This is around 3 6 mls of hardener per litre of working strength HYPAM used This increases the film hardness slightly but has a negligible effect on the fix and wash efficiency When fix and wash times are restricted the maximum amount of HYPAM HARDENER recommended is 10 20ml of hardener per litre of working strength HYPAM used This higher amount gives a definite increase to the hardness of the films processed and while fixing and washing efficiency are reduced the films will be adequately fixed and washed for most purposes When fix and wash times can be extended the maximum amount of HYPAM HARDENER needed to achieve fully hardened films is 1 part to 40 parts working strength HYPAM i e 24 ml per litre Drying To avoid drying marks use a clean squeegee or chamois cloth to wipe 100 DELTA Professional film before hanging it to dry Dry 100 DELTA Professional at 30 40 C 86 10A4 F in a drying cabinet or at room temperature in a clean dust free area STORAGE Store 100 DELTA Professional in a cool 10 20 C 50 68 F dry place in its original packaging Exposed film Once exposed process 100 DELTA Professional as soon as pra
