Adhesive Selection for Electronic Water & Oil Pumps | PCB Potting, Power Module Thermal & Control Board Fixing Solutions

Adhesive selection for electronic water pumps and electronic oil pumps in new energy vehicles focuses on PCB potting, power module heat dissipation and control board fixation. Elaplus recommends SIPA 1850 for PCB potting, TCMP 1941 for power module heat dissipation, and EP 2012 for control board fixation, to address electronic protection, thermal management and structural reliability challenges respectively. Why Adhesive Requirements for Electronic Water & Oil Pumps Are More Complex An electronic pump integrates motors, power devices, PCBs and fluid systems. Compared with conventional electronic control boards, electronic pumps are continuously exposed to: Key application demands for electronic pumps can be summarized as housing sealing, structural bonding and resistance to medium corrosion. Recommended Grade for Electronic Pump PCB Potting SIPA 1850 Two‑Component Thermally Conductive Silicone Potting CompoundWithin electronic water pump / oil pump solutions, SIPA 1850 is designated for PCB potting. Potting mainly delivers the following functions: Since electronic pumps contain components of varying heights, adequate flowability and air bubble evacuation shall be prioritized during potting process design. Recommended Grade for Power Module Thermal Dissipation TCMP 1941 Two‑Component Thermal Gel TCMP 1941 is used for heat dissipation of internal power modules inside electronic pumps. Heat‑generating components such as power MOSFETs and driver devices require efficient heat transfer to the pump body or metal housing, which makes intact thermal interfaces critical. Key evaluation criteria during material selection:‑ Thermal conductivity‑ Interface conformability‑ Hardness‑ Long‑term thermal cycling performance‑ Material stability Recommended Grade for Control Board Fixation EP 2012 Two‑Component Epoxy Structural Adhesive EP 2012 is applied for control board fixation. For electronic pumps subject to persistent vibration, control boards cannot rely solely on screws, fasteners or solder joints. Proper structural adhesives help share mechanical loads.
