Question Answer
Can your products be used to bond dissimilar materials, such as metal to plastic? Yes, our technology is particularly good for bonding dissimilar materials. We have demonstrated strong adhesive performance with polyolefins and metals.
What is the performance of your crosslinkers compared to existing solutions like silanes or plasma treatment? Our products provide greater adhesion than leading polyolefin primers, with a significant performance boost. The crosslinked bonds are strong carbon-carbon bonds that are generally stronger than epoxy . The adhesion on glass, however, is not as strong as with silanes.
What kind of performance data do you have for adhesion to specific materials like PEEK and PEKK? We have designed our crosslinkers to focus on singlet carbenes for insertion into C-H bonds, primarily on aliphatics. For aromatics like PEEK and PEKK, a triplet carbene would work better.
How do your corsslinkers improve the performance of composites and textiles? Our technology can increase the mechanical properties of textiles, such as tensile strength, modulus, and ballistic properties, by strengthening the fibers . We’ve seen good results when using our primer to strengthen peel performance, which is an indicator of improved adhesion for composites.
How well does it work with glass adhesion? Our initial tests on glass show that our product does react, but the adhesion isn’t yet very strong. We could develop a custom molecule to work on this.
When using your system with HDPE, do you see a yellowing of the final result? If heat activation is used for too long, a slight yellowing can occur, but UV activation does not significantly change the color.
How is it helping in terms of CTE when it comes to delamination? We don’t have the testing capacity to know the answer yet, as we are limited to some mechanical and electronic tests and are not equipped to handle CTE, Dk, and Df tests.
Can crosslinkers be applied to photonic films and resins? Yes, if the resins meet certain criteria, our crosslinkers can be used to cure them. The final properties, like the dielectric constant (Dk​), will be based on the starting resin. For example, poly(HNB) is a very low-loss resin that is useless on its own because it is non-curable, and our technology enables it to be cured.
How do our non-fluorinated products work with polyimide? Polyimide is a broad resin class, and our materials would work very well with the right kind of polyimide. We can help with the selection process.
Do you have any papers published about delamination issues? We have some about general adhesion, particularly peel strength, but we have not publicly released that specific data for strategic reasons.
