Dyna Col AC304 is an IPA eliminating fountain solution concentrate for use on sheetfed and continuous stationery offset presses. Dyna Col AC304 is designed to eliminate the amount of isopropyl alcohol and offers a wide dosage latitude. Highly recommended when calcium deposit on ink rollers and blankets causes problems. Dyna Col AC304 contains effective plate preservers and active corrosion inhibitors. Dyna Col AC304 meets the demands as set by the leading press manufacturers and has been approved by ISEGA for the manufacture of packaging material with in-direct food contact.
A 2-3% dosage of this product can replace up to 12% isopropyl alcohol. This product is suitable for water with hardness values of 8-16°dH (German scale). The recommended standard addition is 2-3% (vol/vol), resulting in a pH value of 4,8-5,2, depending on the hardness of the water. The recommended dosage can be varied between 2% (soft water) and 3% (hard water). For every 1% of concentrate added the conductivity increase will be approximately 400 µS/cm.
- Immediate high-density copies by optimal ink transfer
- Wide dosage latitude
- Prevents problems concerning calcium deposit on ink rollers and blankets
- Prevents ink feedback on the dampening rollers
- Fully controlled water uptake by the ink
- Faster and cleaner start-ups
Before adding Dyna Col AC304, it’s important to empty and clean the fountain solution circulation system first. Also, the condition of the dampening system is important. Check whether the fountain solution dosing equipment is accurate and apply the right dosage. For a precise control of the dosage conductivity measurements are recommended. It’s advisable to check the roller settings of the dampening system. When reducing or eliminating IPA a looser roller setting could be necessary.
