Chemical-Photographic processing conditions of VRP photographic film:

Name of the stages Temperature of solutions, water, air, оC Processing time, min.
1. Development in VRP-M developer 20,0 ± 0,5 4,0-6,0
2. Washing in water 17,0 ± 3,0 0,1-0,2
3. Fixing 20,0 ± 2,0 5,0-10,0
4. Washing in water 17,0 ± 3,0 5,0-10,0
5. Drying in the open air 20,0 ± 5,0 to be dried out completely

Photo film is manufactured in rolls and sheets.
The sizes of film are agreed with a customer.
Thickness of base are ranged 175 ± 5, 190 ± 5 micrometers.

Open and process the photographic films under indirect safe light conditions with using a dark-red light-filter № 107 for VRP, VRP-M, PFG-04 photographic films, and with using a dark-green light-filter № 170 for PFG-01, PFG-03M photographic films, and for PFG-03C photographic film with using light-filter № 107 and № 170.

Climate conditions for photographic films usage: temperature of environment is (20 ± 5)оС, relative humidity of air (65 ± 15)оС.

Guaranteed shelf life of photo films:

- in rolls - 18 months.
- in sheets: VRP, VRP-M, PFG-01, PFG-04 - 12 months.
- PFG-03M, PFG- 03C - 6 months.
