Perstorp is a global leader in the supply of core components for high quality Cationic UV/EB curing formulations. This includes TMPO (Trimethylolpropane oxetane) as a reactive diluent and specialty polyols, such as Capa™ polycaprolactones and Boltorn™ dendritic polymers used to fine-tune final properties.

Boost performance, productivity and lower your processing costs

TMPO combines increased reactivity with good diluting power of epoxy resins making processing faster and boosting productivity.  It can also improve a formulation’s through-cure, adhesion and chemical resistance. This makes TMPO the reactive diluent of choice for difficult printing surfaces where you want to prevent delamination and maintain a high quality appearance. 

Premium printing quality and safer packaging

TMPO is widely used for specialist and high quality printing inks and overprint varnishes. Applications include 3D printing (stereolithography), food packaging, metal coatings and other substrates, including flexible surfaces such as sausage skins that are difficult to print on. TMPO is particularly suited for food packaging, as it is safe to use with fewer migration issues and no residual odor. 

Fast and reliable supply when you need it

As the global #1 in TMPO we can guarantee the reliable supply of consistently high quality material as and when you need it. Our flexible approach means that we offer high availability and short lead times even for small quantities. This can be particularly beneficial for new cationic UV curing developments.
