ResinLab offers several epoxy flame retardant encapsulants which are UL listed under the component recognition program QMFZ2 Plastics - Component. These products have been tested and comply with ANSI/UL 94, "Test for Flammability of Plastic Materials for Parts in Devices and Appliances". Several formulas carry the UL 94V0 certification to assure that in event of a fire, the epoxy will self-extinguish. We offer several systems varying in reactivity, hardness and ratio.

  • UR6000

    Product Documents

    ResinLab® UR6000 BLACK is a cost effective, two component, flame retardant polyurethane designed for potting and encapsulating electronic components. This low viscosity formulation allows for a relatively fast gel time that can be further accelerated by mild heat. With a 4:1 by volume mix ratio it can be easily dispensed using automatic meter, mix equipment.

    UR6000 BLACK is UL Certified 94VO self-extinguishing at a 3-3mm thickness.
