Heat expanded SikaReinforcer application in vehicle body cavity shown pre-bake cycle


SikaReinforcer® is a heat-reactive and foamable epoxy material that is used in combination with our SikaStructure® carrier to reinforce vehicle body structures. After curing in the E-coat oven, SikaReinforcer® foam creates a strong connection between the SikaStructure® carrier and the vehicle body’s metal sheets. In this way, SikaReinforcer® can be used to improve NVH (noise vibration harshness) behavior, local stiffness, and crash performance, while also contributing to overall weight reduction (when compared to the equivalent steel design solutions).


SikaReinforcer® is delivered as a part used for stiffness or crash improvement of vehicle body structures. The structural inserts can be robotically or manually inserted into vehicle cavities during the assembly process.

  • Low-density material – due to its expansion properties
  • Expanding foam helps compensate for, and reduce, gaps in the structural assembly
  • Creates a durable and strong connection between the carrier and metal forms in closed cavities
  • Excellent adhesion to oily and E-coated steel, aluminum, and plastic components
