OP-3700 offers hybrid absorber/thermal management material that is used for EMI mitigation. It is a two-component liquid gap filling material, cured at either room or elevated temperature to speed up the curing process. Filler particle composition imparts both excellent thermal conductivity and good EMI suppression in the microwave frequency.

OP-3700 will lightly adhere to surfaces, thus improving surface area contact. The proprietary formulation of OP-3700 is RoHS compliant and halogen-free, providing extra assurance in applications where hazardous substances are forbidden.
