The Importance of Heat and Moisture Resistance in Industrial Adhesive Tapes

In industrial applications, adhesive tapes not only bond surfaces together but must also withstand time, temperature, humidity, and external conditions.

Therefore, when selecting the right tape, resistance to heat and moisture plays a role just as critical as adhesion strength.

At MAS Global, in this article, we explore how tape performance changes under high heat and humidity conditions—and why choosing the right product is vital.

Why Is Heat Resistance Important?

Many environments where industrial tapes are used experience temperature fluctuations.

Especially in the automotive, white goods, metal surface assemblies, or outdoor applications, tapes must maintain their shape and adhesive properties at high temperatures.

Insufficient heat resistance can lead to:

• Adhesive melting or oozing
• Carrier loosening or deformation
• Loss of adhesion, or even complete detachment

MAS Global recommends:

• Acrylic foam tapes → heat resistant up to 120–150°C
• Teflon and aluminum tapes → preferred in high-temperature oven and insulation applications

What Is the Benefit of Moisture Resistance?

In outdoor environments, high-humidity areas, or facilities with significant vapor exposure, tapes must have a waterproof and moisture-resistant structure.

Low moisture resistance can cause the following risks:

• Water accumulation between the surface and tape
• Adhesive breakdown or mold formation
• Short-circuit risk in electrical applications

MAS Global recommends:

• Closed-cell PE and EPDM foam tapes → do not absorb water, fully moisture-resistant
• Film-based transfer tapes → thin, but offer high sealing performance

Key Application Considerations

• The surface must be dry and clean before application
• Tape should be chosen according to the ambient temperature conditions
• In high-humidity environments, a tape + primer combination may be preferred
• For outdoor use, UV resistance should also be taken into account

Conclusion

The selection of industrial tape should not be based solely on adhesive strength, but also on the thermal and humidity challenges of the operating environment.
