Question 1

Which solvents are suitable for dissolving EC-100?

Accepted Answer

EC-100 dissolves readily in ketones (MEK, cyclohexanone), esters (ethyl acetate, butyl acetate), and aromatic hydrocarbons. A blend of toluene and ethanol (80:20 by weight) is the standard reference solvent. EC-100 is not soluble in water, aliphatic hydrocarbons alone, or glycols, though it can be used in mixed solvent systems containing these components.

Question 2

What role does EC-100 play in gravure and flexographic ink formulations?

Accepted Answer

In solventborne gravure and flexo inks, EC-100 acts as a film-forming binder and viscosity modifier. It contributes to fast solvent release on press, improves adhesion to non-porous substrates such as PET and OPP, and builds sufficient tack for pigment hold-out. Typical use levels are 10–20% of total formulation weight based on solids.

Question 3

Is EC-100 compatible with nitrocellulose-based ink systems?

Accepted Answer

Yes, EC-100 is compatible with nitrocellulose and is commonly used in combination at ratios of 1:3 to 1:1 (EC:NC) to moderate brittleness, improve flexibility, and extend the resin matrix. This combination is widely used in packaging gravure inks where both fast drying and film toughness are required.
