Light-Curable Materials for Electric Vehicle Batteries

EV Battery Systems

E-Mobility - Electric Vehicle Battery Systems

Design Battery Packs with Reliable Performance

Protecting electric vehicle battery systems from harsh environments is critical, as e-mobility designs of full electric and hybrid electric vehicles continues to gain traction. The battery is the heart of an electric vehicle and must maintain performance under drastic temperature changes and corrosive elements like salt and sulfur, as well as moisture, vibration, and shock.

To ensure top performance, functionality, and long service life of hybrid and EV batteries, components must be bonded, sealed, potted, or coated. Dymax light-curable materials are suitable for applications using cylindrical, pouch, or prismatic lithium-ion battery designs, as well as applications involving electrical components inside charging stations.

Our light-curable materials cure in seconds for faster processing and higher throughput and are available with many innovative and patented technologies that turn problems like shadow areas, cure confirmation, and difficult inspection into non-issues. Our materials are also solvent free and one-part, requiring no mixing or prep before application. Most products are available in multiple viscosity grades so the material flow can be tailored to the individual application. IPC approved, MIL-I-46058C, and UL listed self-extinguishing grades are available.

Available Light-Curable Materials

Conformal Coatings

Dymax light-cure conformal coatings help protect printed circuit boards in battery management systems (BMS) and charging stations from thermal shock and humidity, and corrosive elements like salt and sulfur. Formulations are available with fluorescing technology, in IPC-CC-830 approved, MIL-I-46058 listed, and UL recognized grades, and with moisture-cure or secondary heat-cure capability.

Potting Materials

We provide potting materials that have excellent bond strength to both plastics and metals. They also provide excellent resistance to chemicals and thermal shock, making them a great choice for fixturing battery cells to the base.


Dymax encapsulants protect critical electronic components throughout the electric vehicle battery system. Standard grades cure in seconds with UV/Visible light, but secondary moisture cure grades are also available for applications where shadow areas are a problem.

Form-in-Place Gaskets

Dymax gasket materials act as a barrier to prevent absorption or penetration of air, dust, noise, liquids, gaseous substances, or dirt for sound dampening, vibration dampening, moisture protection, chemical protection, and air sealing. These gaskets conform to complex and intricate channels, on both vertical and horizontal surfaces, and cure in place upon exposure to light.
