New solutions for PSA applications from Arkema

At the European Coatings Show Arkema presented its new commercial Nanostrength MMA product range, a new class of acrylic block copolymers that are said to offer breakthrough opportunities in the field of pressure sensitive adhesives for thermoplastic adhesive applications. Nanostrength MMA products are based on the the company’s BlocBuilder controlled radical polymerization technology also presented at ECS.

 

 

Nanostrength MMA and Nanostrength functionalized MMA are a family of self-assembling block copolymers that are said to offer a range of advantageous properties:

  • high transparency
  • UV resistance
  • creep resistance
  • temperature resistance
  • easy, or even no need, to formulate, thanks to the presence of an intrinsically tacky soft block in the copolymer
  • soluble in many solvents
  • functionalizable to boost some key properties and to achieve as yet unattainable properties like reversible water absorption (M1H grade).

 

As a result, Nanostrength MMA can be used as adhesive in removable, high-tech optical or medical applications.
