"The attributes of this platform make these adhesives unique in the sense that it targets a niche market while still having the ability to be utilized in more traditional applications such as paper labels and vinyl graphics. The attractive cost structure, various benefits of using water-based PSAs, and highly sought- after sustainable attributes such as repulpability make this platform very appealing and one to add to our customers product offerings."
