While cooling coils are essential in appliance assembly, the chosen adhesive to bond the coils to the refrigerator or freezer cabinet also is critical, as it can improve assembly processes while enabling the appliance to meet new energy savings classifications. Although thermal mastics are commonly used in cooling coil bonding, gain insight into how thermal conductive butyl adhesives offer distinct advantages.
- Energy Efficiency Improvements
Thermal conductive butyl adhesives help improve the appliance’s thermal energy transfer. Applied directly to the coils, these adhesives can offer 20%* higher thermal conductivity when compared to current thermal mastics available in today’s market.
Additionally, by acting as a protective barrier from the insulation foam injection process, thermal conductive butyl adhesives further aid in appliance energy efficiency.
- Decreased Adhesive Use
Offering higher tack and good internal strength compared to thermal mastics, thermal conductive butyls for cooling coil bonding enable plants to use less adhesive overall. Thermal mastics, on the other hand, require greater adhesive use due to their lower level of strength.
- Waste Reduction
Using thermal conductive butyls in appliance assembly decreases the amount of waste produced during manufacturing. For example, no tape is needed as a process aid the way it is with thermal mastics.
Additionally, zero waste is yielded during drum turnover with thermal conductive butyls. Typically in cooling coil bonding, the bottom 5%* of the product’s container is thrown out, rendered too difficult to use. However, with the right chosen adhesive and its smart packaging form, the remaining product percentage can be used, offering cost savings as well.
- Precise Application
Thermal conductive butyl adhesives can be applied at certain temperatures. This allows for manufacturers to control the viscosity during cooling coil bonding application. By controlling the viscosity, adhesive application can be more precise. Thermal mastics, however, must be applied at room temperature without the ability to control viscosity.
