UV-curable (UV-C) hotmelt pressure sensitive adhesives (HMPSA) are – according to their name – hotmelt pressure sensitive adhesives whose internal strength (cohesion) can be significantly increased by UV radiation (mercury lamp). These mainly acrylate-based formulations already replace solvent-based pressure-sensitive adhesives in many cases. In addition to the advantages of standard pressure-sensitive adhesives based on synthetic rubber or water-based dispersions, subsequent curing with UV radiation provides additional possibilities such as higher thermal or chemical resistance – without the use of an inert gas atmosphere.
UV-curable (UV-C) hotmelt pressure sensitive adhesives (HMPSA) from EUKALIN are highly transparent, resistant to a variety of chemicals / plasticizers and are also suitable forsensitive applications due to covalently bonded photoinitiators. Independent of your application temperature, direct or transfer coating or whether you need good cutting properties – EUKALIN offers you tailored UV-C HM-PSA for such as clear-to-clear applications, wash-off labels, tapes and specialities.
Dispersion adhesives from EUKALIN – standard adhesive or tailored to your needs
Also known as cold glue or PVA glue, these adhesives are used for various products. With our innovative R&D and many years of experience we do not only have a broad product portfolio of dispersions at our disposal, we also continue to develop and, if required, tailor the adhesives to your needs. We work closely together with machine and application equipment manufacturers (OEM) to adapt the running behavior of our products to the newest and most innovative conditions. Your adhesive should set faster, have better layflat properties or be required in a special viscosity? Please get in touch with us!
Polyurethane-based (PUR) hotmelt adhesives are applied as a melt like other hotmelt adhesives. The setting and strength build-up takes place in two steps: At first by cooling the melt purely physically and then followed by moisture-initiated chemical crosslinking of the individual prepolymers. Depending on the respective substrate surface, a covalent substrate-adhesive bond can also additionally strengthen the adhesion. PUR-based hotmelts naturally have a high resistance to moisture, water and many chemicals. In adaption to your open or closed application system EUKALIN offers you polyurethane-based (PUR) hotmelts with a wide range of open and setting times.
