VECTOR 4186A styrene-isoprene radial copolymer is produced via proprietary anionic polymerization technology from Dexco Polymers LP, a Dow/ExxonMobil Venture. It is not formulated with the antioxidant TNPP (tris(nonylphenyl) phosphite).
It is made with a patented coupling process that yields a polymer primarily with a 4-arm radial architecture. It is particularly suited for low-viscosity hot melt pressure sensitive adhesive systems having excellent adhesion to low energy surfaces, low migration characteristics, and enhanced die-cutting characteristics within label stock applications.
