Ink and coatings curing

Electron beam curing involves electron initiated free-radical polymerization. EB printing inks, coating or adhesives are highly reactive chemical systems consisting of pre-polymers and monomers. These systems do not contain solvents! They are applied with conventional coating methods onto the substrates.

Radiation curing of inks and coatings by means of electron beam have been around since the 1960’s. However, they have only recently became widely accepted, they are therefore still considered “new” technology.

Electron beam curing involves electron initiated free-radical polymerization. EB printing inks, coating or adhesives are highly reactive chemical systems consisting of pre-polymers and monomers. These systems do not contain solvents! They are applied with conventional coating methods onto the substrates.

During the electron beam treatment the materials are modified in a few milliseconds, after which the product treated is completely converted or cured and available for further operations. The typical dose range for ink curing is 5-30 KGy.

Key benifits of the technology:

• Environmentally friendly due to the lack of solvents. EB inks contain 100% solids
• No or low substrate heating
• EB consumes less energy than thermal or UV drying.
• EB inks and coating do not contain photoinitiators: therefore no odour, no yellowing and no skin irritation.
• EB inks are less expensive than comparable UV products
• Higher gloss, better scratch-abrasion and chemical–resistance of EB inks
• EB can penetrate deeper then UV in material

• Proven technology
