Isopropylalcohol (IPA)

Isopropyl alcohol (> 99 %) for offset printing

Application

Isopropyl alcohol is a highly effective wetting-agent additive for the fountain solutions in sheet-fed and web offset printing.

Features and Benefits

Significant reduction of the surface tension in the fountain solution
Improved wetting of the printing plate and uniform film formation
Stabilises the ink and water balance and widens the printing process window
Cooling effect through evaporation – supports a constant roller temperature

Anwendung

Add to the fountain solution via the dosing or circulation unit of the press. Typical dosage 3 – 12 %, depending on press type, dampening system and printing conditions. Keep the amount used as low as possible (aim for IPA-reduced or -free printing), preferably in combination with a Hydrolith fountain solution concentrate. Observe VOC, safety and explosion-protection (Ex) requirements.
