Dow Corning Innovation
Introducing a reactive hot-melt silicone sealant technology that provides instant green strength to increase productivity, improve quality and reduce costs in industrial assembly applications.
Introducing
Dow Corning HM-2500 Assembly Sealant is a patented, neutral-cure, reactive hot-melt silicone that is ideal for automated applications in the manufacturing of various components.
HM-2500 is optimized for use with automated dispensing equipment, which creates a uniform seal for part-to-part consistency, minimizes sealant waste and cleanup, and can reduce labor costs substantially.
