Kao Collins releases Sigma solvent ink

Kao Collins releases Sigma solvent ink

Kao Collins has launched Sigma, a solvent ink for HP 45si thermal inkjet technology to reduce the wiping and purging of nozzles.

According to the company, Sigma achieves fast curing without external heat sources and increases decap to at least four times that of other inks currently available on the market. The aggressive solvent dries quickly on plastics, while Sigma offers much better decap properties. 

‘We saw how many solvent ink users struggled with the short decap. This ink changes everything and sets Kao Collins apart with Sigma,’ said Kristin Adams, marketing manager for Kao Collins. 

The lab testing also confirmed Sigma’s shelf life for individual cartridges of at least 12 months. With further testing chemists at Kao Collins expect results showing an even longer shelf life in the future. 

Sigma is ideal for mailing and addressing industries along with packaging converters. The ink adheres to more substrates, including films such as BOPP, PE, PET and PP, foils, a variety of label materials, some metals, and many other non-porous materials.
