The best of both worlds

Sometimes things just seem too good to be true and they most often are. However, GENOMER* 4267 urethane acrylate is just that good when considering its many advantages such as exceptional post-cure durability, toughness and adhesion to metal.

Say goodbye to brittle coatings that shatter on impact. This aliphatic urethane acrylate offers outstanding impact resistance and adhesion to carbon steel, aluminum and stainless steel.

Its weathering performance based upon resistance to yellowing, cracking and gloss loss is outstanding. These attributes make it a perfect addition to your formulating toolbox.

Whether your focus is on industrial primers and coatings, construction adhesives, or automotive applications, GENOMER* 4267 delivers exceptional bonding and resistance characteristics, guaranteeing a reliable and long-lasting solution for your project.

The TPO regulatory challenge and the possible alternative solutions

Back in February 2023, the European Chemicals Agency (ECHA) launched a 45-day public consultation on the proposed SVHC listing of TPO. The consultation has now closed but the feedback will, to some extent, determine what happens next. In a nutshell, it is assumed that TPO will be officially listed on the SVHC list sometime this year. As and when TPO is listed, RAHN will update the SDS and our customers will be informed.

TPO is currently classified as reprotoxic category 2. However, it is assumed that the substance will be reclassified later this year, after the SVHC listing, as reprotoxic category 1B. When that happens, the SDS and labels will go through a second round of updates.

Given the upcoming classification changes, we recommend that you consider substituting TPO by more suitable alternatives such as GENOCURE* TPO-L, GENOCURE* BAPO and mixtures thereof. Should you have any questions, please contact your RAHN-Sales representative to discuss how you can best replace TPO in your existing formulations.

Now you see it, now you don't

Expanding at a level of 6-7% annually, shrink sleeve printing continues to gain labeling market share where acceptance stems from the features that this unique technology can provide. Besides offering an eye-catching, full coverage label, the technology can also provide package and product protection from abrasion, moisture, and light, while maintaining a tamper-evident barrier, if required.

Historically, an inability to easily recycle PET containers with shrink sleeve labels has limited market acceptance, while higher growth rates could have been achieved with a better recyclability profile. Printers and brand owners have addressed this issue by creating label systems that may be removed from the package prior to the recycling process or through technology that allows the label to be recycled with the containers without contaminating the clear PET package material.


Specially formulated solventborne inks can meet the required recyclability profile and are commercially available today. For those desiring a UV approach, RAHN offers excellent options with our high functionality, low viscosity polyether acrylate products.

These oligomers can be used to formulate flexo inks that offer superior shrinkability and adhesion while enabling efficient de-inking in the recycling process. Inks formulated with RAHN's PE oligomers form particulates that can be easily separated in the caustic wash step of the recycling process without contaminating the wash solution or the PET and thus allowing for the capture of "clean" recyclable substrates.
