Product Description

TaxoTape® TX-PTCSA-T series is a two-component polyurethane thermally conductive structural adhesive, engineered for cell-to-cooler plate bonding in battery energy storage systems (BESS) and electric vehicle battery modules. It delivers a combination of reliable thermal conductivity and high-strength structural bonding in a single material — eliminating the need for additional mechanical fasteners while ensuring efficient heat transfer from battery cells to the liquid cooling plate.

The adhesive cures at room temperature, offers excellent flexibility after cure, and maintains stable performance across a wide temperature range. It is designed to withstand the thermal cycling, vibration, and moisture exposure inherent in demanding energy storage environments.

Fully compliant with EU RoHS requirements. Available in 400ml dual cartridges, compatible with standard dispensing guns and automated dispensing equipment.

Applications

▷ Cell-to-liquid cooling plate bonding (BESS / EV battery modules) ▷ Cell-to-cell structural bonding in battery pack assembly ▷ Battery Management System (BMS) thermal bonding ▷ Energy storage cabinet thermal management ▷ Industrial equipment, solar panels, and automotive electronics requiring combined thermal conductivity and structural adhesion

Why Use a Thermally Conductive Structural Adhesive Instead of Thermal Pads or Gels?

Traditional thermal pads and gels provide thermal conductivity but offer no structural bonding. In modern BESS and EV battery module designs where cells are bonded directly to liquid cooling plates without mechanical fasteners, a thermally conductive structural adhesive is required — it simultaneously transfers heat and secures the cells in position. The polyurethane chemistry offers the flexibility needed to absorb stresses from thermal expansion and contraction across thousands of charge/discharge cycles.
