Hernon® Develops Breakthrough UV Curable Adhesive for Versatile Plastic Sealing

Hernon Manufacturing, Inc.® is proud to unveil Hernon Ultrabond Sealant 721, a cutting-edge UV curable adhesive designed to deliver exceptional sealing capabilities for a wide range of plastics. This revolutionary sealant forms a water-tight bond with excellent environmental resistance, ensuring optimal performance in various applications.

One of the standout features of Ultrabond Sealant 721 is its ability to prevent material from escaping through a crimped seal.
