Functional Monomers: KarenzTM

Karenz™ is our highly specialised product family to support radcure technology.

Our unique lineup of products facilitates the performance enhancement of your materials or formulations for radiation curing of paints, coatings and adhesives in a wide range of applications.

Hybrid monomers of different functional groups of isocyanate (NCO) and double bond in one molecule as well as multifunctional secondary thiol monomers will expand the possibilities to achieve a more efficient and easy design and synthesis for your products, typically for polymers (oligomers).

We believe that Karenz™ will help to develop new products with higher performance and lower environmental impacts.

Isocyanate Monomer / Methacrylates

 

High purity monomers

All products grouped under Karenz MOI are characterised by their methacrylate group and isocyanate group. A variety of derivatives are available, in order to match your specific molecular design needs. These monomers offer easy and flexible molecular design; and can be used for various purposes, including paints, coating base materials, surface modification, adhesives and photosensitive resin base materials and many others.
