About 3616 Electrically Non-Conductive Adhesives
LOCTITE 3616 is a 1-part, red, high-viscosity epoxy adhesive for bonding surface-mounted devices (SMDs) to printed circuit boards (PCBs) before wave soldering. Its designed for applications requiring high print speeds and high wet strength characteristics. Its particularly used for printing a range of dot heights from one stencil thickness, but is also suitable for general small-part bonding. It cures when exposed to heat above 100C (212F), typically 90120 seconds at 150C (302F).
- Suitable for high print speeds
- High wet strength

FAQ's of 3616 Electrically Non-Conductive Adhesives:
Q: How is 3616 Electrically Non-Conductive Adhesive applied in electronics assembly?
A: This adhesive is applied directly as a paste onto grit-blasted steel or other compatible electronic components. After application, it requires heat curing to activate the bonding process, ensuring secure attachment and effective insulation for surface mount technology.
Q: What are the main benefits of using this adhesive for surface mount applications?
A: The 3616 adhesive delivers outstanding electrical insulation, robust mechanical strength, and high thermal resistance. These qualities make it ideal for electronics manufacturing, as it helps protect sensitive components and supports durable, long-term device reliability.
Q: When should this adhesive be cured for optimum results?
A: For best bonding outcomes, the adhesive should be heat-cured immediately after application. This ensures strong adhesion and consistent performance in electronics assemblies.
Q: Where is this adhesive most commonly used?
A: It is widely used in electronics assembly lines, particularly for surface mount devices that require secure, electrically non-conductive bonding on steel and other grit-blasted surfaces.
Q: What is the recommended storage condition for 3616 adhesive?
A: To preserve its properties and shelf life, the adhesive should be stored at temperatures ranging from 2C to 8C in its original container until ready for use.
Q: How does the adhesive maintain non-conductivity in electronic assemblies?
A: Formulated with a thermoset material, this adhesive maintains reliable insulation by preventing electrical conductivity between connected components throughout the product's life cycle.
