DSM NeoResins+ has added an elastomeric aliphatic (mild) solvent-based urethane material to its ink resins. The new product is suitable for flexographic or gravure printing, on a wide range of packaging film substrates, according to the Dutch company.
The new material, NeoRez U-471, fits the group's environmental philosophy: it is tin free and contains a non-aggressive (mild) solvent. It combines aliphatic building blocks and excellent pigment wetting plus high bond strengths in packaging film laminates. DSM points out that this means it can be used to formulate inks to undergo sterilisation and pasteurisation.
As a non-yellowing material with better alcohol tolerance compared to aromatic urethanes, it is even more suitable for flexographic printing uses.
DSM commented in a 29 Feb announcement on the new resin that "The universal nature of elastomeric (mild) solvent-based urethane has led to significant cost savings for printers." This aspect is driving the adoption of such materials in the leading growth market of packaging film laminates, the company points out.
"Here we see traditional technologies like vinyl chloride and polyvinyl butyral resins in decline," DSM NeoResins commented.
