Clariant, a sustainability-focused specialty chemical company, has launched a set of wetting and dispersing agents that enable coatings’ manufacturers to extend the open time of their acrylic lacquers and polyurethane (PU) lacquers, and lengthen current post-application correction windows for these water-based systems.

According to the company, customers can have confidence in finding the perfect match for their specific requirements from the new portfolio. Clariant has used its two new industry-leading in-house open-time testing methods to assess each additive in both paint systems using fast and reproducible measurements, which avoids the inaccuracy of the visual evaluation and low reproducibility of the current standard industry methods. As well as support for extending open time, the wetting and dispersing agents also offer formulators the possibility to solve multiple problems at once. The multifunctional additives have been tested for their performance regarding blocking resistance, gloss, leveling, and sagging, highlighting the potential for even more end-product improvements.

Clariant’s open-time extenders include EcoTain labeled solutions recognized for their outstanding sustainability advantages.
