To
achieve improved adhesive performance, two high-efficiency four-arm radial
styrene-isoprene-styrene (SIS) block copolymers were developed by Dexco
Polymers L.P. for hot-melt adhesive (HMA) and pressure-sensitive adhesive (PSA)
applications.
Once a fringe player, solventless adhesives have become a workhorse in the laminating industry. Coim’s Dave Engel discusses how this happened and why solventless is such an attractive alternative to solvent-based adhesives.
