Dow Corning EA-4600 : New Hot Melt Room-Temperature Vulcanization (RTV)

1429177600.jpgDow Corning, a global leader in silicones, introduced new Dow Corning® EA-4600 Hot Melt Room-Temperature Vulcanization (RTV) Black Adhesive for improved assembly of electronics applications. The latest addition to the company’s broad and growing portfolio of advanced hot melt adhesives, Dow Corning EA-4600 Hot Melt Adhesive is uniquely formulated to dispense easily and achieve instant green strength, which allows electronic assemblies to be handled immediately after its application.

The new Dow Corning EA-4600 Hot Melt Adhesive is a reactive material that can be applied neatly as a liquid melt in very thin, <0.5-mm-wide, bonding lines. It cools quickly and cures at room temperature to become a viscoelastic polymer that provides strong, flexible, primerless adhesion to common plastic (like Polycarbonate (PC) or Teflon® (PTFE)), and metal substrates.

As the Dow Corning EA-4600 is a silicone based, this advanced technology offers extended service temperatures from -40°C to 150°C. It incorporates ultraviolet (UV) markers to support automated UV inspection of finished parts. Once fully cured, Dow Corning EA-4600 Hot Melt Adhesive delivers outstanding, durable protection against chemicals, water and dust to enhance the reliability and performance of high-value electronics assemblies.

This new adhesive is a solventless, one-component, moisture-cure silicone material that offers longer open time and pot life (1day) compared to others chemistries, that explain the existence of the 300cc cartridge packaging. The standard 30cc cartridge is also available to meet the requirements of the industries standards.
