UV-curable pressure sensitive adhesives find application on tapes, labels and other specialty applications – especially those demanding high-temperature stability and solvent resistance. UV PSAs have demonstrated improved performance on PVC, elastomers and polyethylene. Increasing environmental pressures are forcing users to find alternatives to the traditional solvent-based PSAs. Many are turning to UV PSAs where new formulations are coming to market due to growing demand. Check out how Heraeus Noblelight America supported a hands-on seminar about a new industrial PSA.

The advantages of using UV-curing technology for PSA applications include:
- Low application temperature (120 -140 degrees Celsius)
- Solvent free
- Improved shear resistance at high temperatures
- High chemical resistance
- Low installation costs
- Increased production rates
- Reduced downtime
A variety of UV-curable PSA formulations are available, with the proper choice depending on the needed characteristics and customer specifications. Some systems currently available include:
- UV-reactive styrenic block copolymers (SBCs)
- Cationic curing epoxy-functional liquid rubbers
- Saturated polyacrylat with grafted PI to the backbone, reaction through photo-reduction
- Acrylated polyesters
Heraeus Noblelight America's high intensity lamps are especially suited to curing heavy film weights, 60 to 80gsm+, such as those used for industrial tapes. Shell products (styrenic block copolymers) have been particularly effective in these cases. The reduced heat output of Heraeus Noblelight America’s lamps is also a benefit for heat-sensitive films. In addition, customers find our lamps to be the equipment of choice when a consistent cure is needed across the entire width of a wide web.
