MG Chemicals 9200FR - Flame Retardant Structural Epoxy Adhesive

9200FR is a toughened, flame retardant, 2-part epoxy adhesive, designed to create long-lasting load-bearing joints. It creates tough vibration resistant bonds and is especially useful for joining dissimilar materials that will experience thermal cycling stresses or harsh environmental conditions. This smooth, non-sagging, thixotropic adhesive is excellent for use on vertical surfaces, for gap filling, and for potting electronics enclosures with gaps where a non-thixotropic encapsulant would flow through.

Applications & Uses

Application Method
Recommended Preparation

Clean the substrate with Isopropyl Alcohol, MG #824, so the surface is free of oils, dust, and other residues.

Syringe or Cartridge

  • Twist and remove the cap from the cartridge or syringe. Do not discard cap.
  • Dispense a small amount to ensure even flow of both parts.
  • (Optional) Attach a static mixer to the 9200FR-50ML.
    • Dispense and discard 3 to 5 mL of the product to ensure a homogeneous mixture.
    • After use, dispose of static mixer.
  • Without a static mixer, dispense material on a mixing surface or container, and thoroughly mix parts A and B together.
  • To stop the flow, pull back on the plunger.
  • Clean nozzle to prevent contamination and material buildup.
  • Replace the cap on the cartridge or syringe.

Dispensing Accessories
