Question 1

How does LAI-5 address pinholing in high-speed gravure printing?

Accepted Answer

LAI-5's modified cellulose component reduces ink surface tension rapidly during film formation, while the silicone fraction promotes uniform flow. This dual mechanism allows solvent to escape evenly before the film solidifies, preventing the micro-bubbles responsible for pinholing at high press speeds.

Question 2

Which solvent systems is LAI-5 compatible with?

Accepted Answer

LAI-5 is designed for solventborne systems based on aromatic hydrocarbons, esters (ethyl acetate, n-propyl acetate), and ketones commonly used in gravure and flexographic inks. It is not recommended for purely aliphatic systems where solubility is limited. Always confirm compatibility at bench scale before full production.

Question 3

What is the best way to incorporate LAI-5 into an ink formulation?

Accepted Answer

Add LAI-5 to the base solvent before pigment dispersion, or pre-dilute at 1:1 in ethyl acetate for easier handling. Typical dosage is 0.3–1.5% on total ink weight. Doses above 1.5% may reduce ink tack; evaluate slip and release properties when pushing toward the upper end of the range.
