Three Bond 2212B One-Component Epoxy Resin Adhesive for Electronic Component Fixing and Sealing

1, Product Overview

Three Bond 2212 is a one-component epoxy resin designed for bonding, fixing, and sealing electrical and electronic components. As electrical and mechanical components become increasingly miniaturized and lightweight while achieving higher performance, the requirements for encapsulating materials in terms of chemical, thermal, and physical properties continue to rise. At the same time, there is growing demand for excellent handling properties to support automation in assembly technology and accelerate manufacturing processes. Three Bond 2212 was developed to meet these requirements.

2,Key Benefits

• One-component and solvent-free; no weighing, mixing, or stirring required, making it extremely suitable for automatic dispensing systems.

• Fast curing enables considerable energy savings and supports assembly automation, allowing on-line integration into manufacturing processes without manual work.

• Contains over 99% non-volatile substances, resulting in almost no outgassing and shrinkage during curing.

• The cured resin offers excellent electrical properties, high strength, and outstanding chemical resistance.

• Ideal for fixing and sealing electrical and electronic components such as relays, sensors, coils, microchips, switches, and terminal blocks.

3, Typical Properties

4,Applications
Three Bond 2212 is suitable for fixing and sealing electrical and electronic components. Typical applications include:

• Relays

• Sensors

• Coils

• Microchips

• Switches

• Terminal blocks

• Other electrical/electronic components requiring bonding, fixing, sealing, or encapsulation

5, Instructions for Use

• Keep the epoxy resin in its original container tightly closed and store it in a dark, dry, well-ventilated, and cool place.

• Allow the product to reach room temperature before opening the container; otherwise, condensation may form.

• For optimal results, remove moisture, grease, and other contaminants from the bonding surfaces.

• Apply an appropriate amount of epoxy resin evenly to one of the bonding surfaces according to the joint conditions (width, roughness, unevenness, etc.), then immediately join the parts, position them correctly, and fix them.

• The degree of curing varies depending on layer thickness, ambient temperature, and process duration.

• When using precision resins, changes in viscosity as a function of ambient temperature can be checked.

• Once dispensed, the product should not be poured back into the original container. Excess material can be easily removed with a cloth.
