Silicone Sealants for Industrial Assembly and Maintenance
Silicon-based Dow Corning sealants last longer and are more versatile than most organic polymer sealants. They
are durable, one part RTV sealant, cure at room temperature to a tough, rubbery solid with exceptional performance
characteristics, and meet a wide variety of your industrial bonding and sealing needs.
Features of Dow Corning silicone sealants include:
■ Stability over a wide temperature range – When fully cured, our products can be used at temperatures ranging from -85° to 599° F (-65° to 315° C).
■ Weather resistance – High resistance to UV rays, radiation and weather prevents our products from hardening,
cracking, crumbling, drying and becoming brittle.
■ Chemical stability – Our sealants do not readily degrade even under long-term exposure to many chemicals and atmospheric pollutants.
■ Good bond strength – Our products provide good adhesion to a wide variety of industrial materials, including glass, ceramics, and wood masonry, painted surfaces, and many metals and plastics.
■ Electrical properties – Designed for a variety of applications, our products can be used in various electrical and electronic applications, including devices that are thermally cycled over a wide temperature range.
■ Low Flammability – In fire conditions, silicone adhesives/sealants are reluctant to burn. Many products comply with UL flammability standards.
When you specify an assembly and maintenance product from Dow Corning, you receive a solution backed by the
world leader in silicone technology with more than 60 years of expertise and innovations.
Innovative Technology
Reactive hot-melt silicone technology provides instant green strength which can increase productivity, improve quality and reduce costs in industrial assembly applications.
Dow Corning® HM-25XX Assembly Sealants are patented, neutral-cure reactive hot-melt silicones ideal for automated applications in the manufacturing of various components. When used with standard hot-melt dispensing equipment and an automated robot, HM-25XX Assembly Sealants become part of the productivity solution that enables parts to be produced faster, better, and more economically.
■ Immediate green strength – parts move efficiently from one step to the next
■ No “hold timeâ€� required – ship parts as fast as you make them
■ Long Pot Life and Long Open Time – material stability, is not heat cured, does not cure in line
■ Aggressive Adhesion – excellent primerless adhesion to metals, plastics, wood, and paints
■ Clear - Ultra clear, clear, or select colors
■ Worker Friendly – non-hazardous formulation, very low odor, very low voc
Neutral-Cure 100% Silicone Chemistry – cure to flexible, weather-resistant, silicone elastomer with outstanding durability and UV resistance
