EMI-Absorbing Coatings for Electronics, Aerospace, & Defense Systems

MagMR is a new advanced EMI coating developed using the patented MOLECULAR REBAR® technology platform from Molecular Rebar Design, Austin, Texas. MagMR is a lightweight, spray-applied nanocomposite coating designed to reduce electromagnetic signatures while protecting sensitive electronics and sensors. Unlike conventional EMI paints that primarily reflect electromagnetic energy, MAGMR absorbs a significant portion of incident energy and converts it into low-level heat that is dissipated through the carbon nanotube network.

Thermally conductive

MOLECULAR REBAR enhances thermal conductivity of materials and provides more confidence in assembly because of more robust handling and durability.

  • Addition of as little as 0.5% by weight of MR in filled thermal materials can improve thermal conductivity by 30% or more.
