- Application Instructions
For best results, follow the procedure below. For quantities less than 1 mL or for stricter stoichiometry control, mix by weight with a high-precision balance. Heat cure to achieve optimal conductivity.
Syringe or Cartridge
To insert the cartridge in the gun, see the Application Guide section for dispensing accessories.
- 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.
- a. Dispense and discard 3 to 5 mL of the product to ensure a homogeneous mixture.
- b. 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
Consult the table below for appropriate accessory selection. See the Application Guide for instructions on using the dispensing accessories
Cat. No. Dispensing Gun Static Mixer 8329TCF-50ML 8DG-50-1-1 N/A - Compatibility
Adhesion - 8329TCF epoxy adheres to most plastics and metals used to house printed circuit assemblies; however, it is not compatible with contaminants like water, oil, or greasy flux residues, which may affect adhesion. In case of contamination, first, clean the surface to be coated with MG Chemicals 824 Isopropyl Alcohol. For substrate substances with weak adhesion strengths, surface preparation such as sanding or pre-coating with a suitable primer may improve adhesion.
Chemical resistance - Once cured, the epoxy adhesive is inert under normal conditions. It will resist water and salt exposure. It is expected to resist short term exposures to fuels or similar non-polar organic solvents, but it is not suitable for prolonged exposures. Avoid use with strong acids, strong bases, or strong oxidizers.
