DELO KATIOBOND

Light-curing cationic adhesives from DELO

DELO KATIOBOND adhesives are light-curing epoxies that cure via cationic polymerization. They are characterized by their high adhesive strength, low shrinkage and excellent resistance to chemical and thermal influences. They are suitable for demanding bonding applications in the automotive and consumer camera sectors as well as for optical applications and electric motors.

Various process possibilities

Innovative light-curing solutions

Our DELO KATIOBOND products come with different light curing mechanisms. This results in a wide range of process possibilities for our customers. Together we will find the best solution for your process.

  • Direct light curing: In direct light curing, the adhesive is exposed to UV or visible light to trigger polymerization. This process is ideal for applications where immediate curing is required and allows precise control of the curing area.
  • Preactivation with light: Preactivation, also known as living polymerization, allows the adhesive to be activated first. During the so-called open time, it retains its flowability, can be processed flexibly and subsequently cures completely at room temperature.
  • Activation on the flow: With activation on the flow, light activation takes place inside a transparent dispensing tube during the dispensing process. This is particularly efficient and opens up new process possibilities. As the dispensed adhesive is already activated, it then also reliably cures in shadow zones and undercuts.
  • Preactivation with subsequent light curing: Some systems contain both a light initiator for pre-activation and a UV initiator for direct light curing. This means that adhesives that have been pre-activated (e.g. via the activation on the flow process) can then also be cured quickly with UV light. This enables even faster further processing.

The right adhesive for every application

DELO offers a wide range of DELO KATIOBOND products, each of which has been optimized for its specific application field.

Therefore they can be a perfect choice for demanding bonding and potting applications in the automotive, consumer electronics and optical bonding sectors.
