Question 1

What is the difference between RS (regular soluble) and SS (spirit soluble) nitrocellulose grades?

Accepted Answer

RS (regular soluble) grades dissolve in ester/ketone/glycol ether solvents and are the standard choice for flexo and gravure printing inks. SS (spirit soluble) grades are specifically formulated to dissolve in alcohol-based solvent blends, making them suitable for packaging applications where strong solvent retention could be problematic. RS grades generally offer broader solvent compatibility and faster solubility.

Question 2

How do I choose the right viscosity grade — RS 1/4 sec, RS 1/2 sec, or RS 1 sec — for flexo vs gravure applications?

Accepted Answer

Lower viscosity grades (RS 1/4 sec) produce lower-viscosity solutions at equal concentration, which suits high-speed gravure printing where ink must flow quickly into fine cells. RS 1/2 sec is a versatile mid-range grade for general flexo and gravure. RS 1 sec provides higher film-build per coat and is preferred for flexographic inks requiring good laydown and body. Always balance grade selection against the solvent blend and press speed.
