As with conventional two-part Lewis Acid cured adhesives, the UV light generated super acid in Fielco’s new adhesive product, IRIS 3030, remains active, allowing the adhesive to continue to cure once exposure to UV light has ceased. The reaction rate can be accelerated with heat, or the reaction process can be slowed down by adding components that temporally tie-up the super acid.

Utilising the properties of cationic cured epoxies makes lamination of UV opaque films via the print, cure and nip process possible. Metalised films, PET (polyethylene terphalate), and opaque PP (polypropylene) can be bonded using this UV curing process. The adhesive is applied to one film and exposed to UV light. At this point, the adhesive is transformed into a tacky PSA (pressure sensitive adhesive). Next, the second film is bonded to the adhesive coated film. If necessary, the laminate can be die cut. The tacky adhesive continues to cure for 24 hours at room temperature forming a tack-free bond.

Fielco Adhesives’ IRIS 3030 masters bonding any combination of plastics, glass and metals whether UV transparent or UV opaque. This new adhesive provides distinct advantages in applications, such as high-speed laminating, where performance and assembly efficiency are critical. In the past, UV adhesives would bond provided that one of the substrates to be adhered was UV transparent. Now, with the capability of bonding any combination of plastics, glass and metals whether UV transparent or opaque, the application opportunities for this new adhesive are endless.

The IRIS 3030 series of adhesives offer the following additional properties:

The IRIS system is customisable to meet specific open time, bond strength, flexibility, and viscosity requirements.
