PUDs are used in many applications such as adhesives and coatings for leather, textiles, wood and automotive.
In response to customer interest, and to increase the formulation window, Perstorp is in the process of launching two new grades – Ymer N90, with a longer EO chain, and N180, with a shorter EO chain.
Ymer will allow customers to formulate solvent-free PUDs and minimize the level of harmful amines in production and during application.
“The current Ymer N120 has proven very popular and Ymer N90 and N180, will help producers to further optimize PUD formulations in terms of dispersibility, stability, hardness and flexibility, meeting their and their customers’ needs,” said Henrik Aplander, Perstorp business development director.
Ymer, for example, can be used to change the surface feeling of leather making it ideal for use in the synthetic leather industry where there is a strong trend away from the use of solvents. Ymer is ideal to support customers in this transition.
“Asia is a strong growth market in many of the industrial segments in which Ymer is gaining traction. We are pleased to continue to strengthen our offering in this region, in order to be an ideal partner for our customers located here, and we look forward to collaborative discussions at ChinaCoat,” said Peter Zhang, Perstorp’s regional sales manager in China.
Ymer N180 will be available for samples in December with N90 released in early 2020.
