Isopropyl alcohol absolute (Isopropanol A)

Description

Characteristics

The main function of alcohol is to ensure the rapid transfer of the fountain solution and to level the water film, allowing the fountain solution to form a thin, uniform layer on the dampening rollers and the printing plate.

Properties

• Functions as a dampening agent: adding 5% isopropyl alcohol to tap water reduces surface tension from 75 mN/m to 50 mN/m

• Provides lubricating action, preventing excessive friction

• Enhances selective wetting of the printing plate

• Improves solution transfer within the dampening system

• Evaporates rapidly without accumulating on rollers or ink

• Reduces ink emulsification and supports a stable ink-water balance

Application of Isopropanol

• The optimal dosage of alcohol is 5-12% of the dampening solution volume, depending on printing conditions.
• Adding 5% isopropanol to water reduces surface tension from 75 mN/m to 50 mN/m.
• A 10% IPA concentration increases water viscosity from 1 mm²/s to 1.5 mm²/s.
• Recommended dampening solution parameters: pH 4.9-5.5, 800-1600 μS.
• For a precise selection of additives based on production specifics and water type, we recommend consulting SNE.T technical support.
• To maintain the dampening system clean, a quick flush using Chembyo A+B is recommended.

CAUTION – TOXIC!

Storage Conditions:

• Store at a temperature not below 6°C and not above 40°C.
• Keep the container tightly sealed.
• Avoid direct sunlight exposure.

Packaging: 20L, 200L, 1000L
