Huntsman Araldite AV138 M + HV998-1 Epoxy Adhesive Kit (1 kg + 0.4 kg, Total 1.4 kg)

Huntsman Advanced Materials · Two-Component Epoxy · Structural Bonding · In stock

The Araldite AV138 M / HV998-1 kit is a Huntsman two-component structural epoxy system supplied as a 1 kg resin can plus a 0.4 kg amine hardener can (total 1.4 kg). AV138 M is a low-viscosity, general-purpose epoxy resin; HV998-1 is the matching amine curing agent. The cured system delivers high bond strength on metals, ceramics, glass, rigid plastics, wood, and composites, and is rated for continuous service from −55 °C to +120 °C with a glass transition around 85–95 °C. KOEED supplies this Araldite kit as part of our industrial-maintenance consumables lineup, the same channel our customers use to source Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic, and KEYENCE spares.

1. Key Technical Specifications / Overview

2. Application Scenarios / Where It Fits

Araldite AV138 M + HV998-1 is a general-purpose structural adhesive and potting compound, so it lands well in any industrial-automation maintenance cell where you are repairing the hardware that sits between a PLC and a moving axis. Typical use cases include:

• Sensor and encoder housing potting — sealing proximity switches, photo eyes, and KEYENCE vision-system cable glands against oil and coolant ingress on machine tools.
• Motor-magnet and rotor assembly bonding — magnet fixturing on servo rotors from Mitsubishi MR-J4, Yaskawa Σ-7, and Panasonic MINAS A5/A6 families.
• Transformer coil and inductor encapsulation — low-viscosity penetration into windings on SMPS units feeding Schneider Modicon and Allen-Bradley PowerFlex drive DC buses.
• CNC fixture and way-cover repair — bonding fiberglass wear strips, chip pans, and way-cover brackets on Fanuc 0i / 30i machining centers.
• Metal-to-metal and ceramic-to-metal structural bonding — bracket-to-frame, terminal block, and heatsink-to-chassis joints inside Siemens SIMATIC and Omron SYSMAC cabinets.
• Composite layup and fiberglass patch repair — field-level repair of robot end-effector covers, cable-carrier tow arms, and protective enclosures on automated cells.
• Chemical-resistant coating — thin film on sumps, drip trays, and chemical-dosing skids in process-control panels.

3. Integration & Wiring Notes (Mixing Ratio, Pot Life, Cure)

Although this kit is a chemical consumable rather than a wired module, the "integration" workflow is just as critical. Treat the resin and hardener the way you would treat a two-wire sensor pair: respect the ratio, respect the timing, and the bond line will hold rated load.

• Mix ratio: 100 parts by weight AV138 M to 40 parts by weight HV998-1. A kitchen scale accurate to 1 g is enough for the 1.4 kg kit. Deviation beyond ± 5 % will leave unreacted amine (sticky surface) or unreacted epoxy (brittle, low Tg).
• Pot life: 60 – 90 minutes at 25 °C for a 100 g mix. Larger batches exotherm and shrink pot life — mix only what you can pour in 20 minutes. Cold kits (chilled to 10 °C) extend pot life but must be warmed to room temperature before application to avoid crystallisation.
• Cure schedule: Pick one and stick to it. 24 h at room temperature gives full handling strength for non-structural bonds; 4 h at 60 °C or 2 h at 80 °C drives the cure to the 85–95 °C Tg window for high-temperature service. Heat-cure is mandatory if the bond sits near a Yaskawa Σ-V servo or a Fanuc αi amplifier heat sink.
• Viscosity management: The 3.5–5.5 Pa·s resin wets fiberglass and fine wire bundles well. Do not thin with generic solvents — use only manufacturer-approved diluents, or the Tg and chemical resistance will drop.
• Health & safety: Uncured amine hardener is a sensitiser. Wear nitrile gloves and work in a ventilated area; cured epoxy is biologically inert. Refer to the SDS before first use.

4. Installation & Commissioning Tips (Surface Prep, Bonding Procedure)

A two-part epoxy fails at the interface, not in the glue line, so surface preparation is at least 70 % of the result. Walk through the procedure in this order:

1. Degrease. Wipe both faces with acetone or isopropyl alcohol; let them flash off completely. Skip this on oily production-floor steel and the bond will be the weakest part of the assembly.
2. Mechanically abrade. 80 – 120 grit aluminium-oxide paper gives the right profile. Glass-bead blasting is preferred for aluminium and stainless housings around KEYENCE laser-sensor mounts.
3. Re-clean. Acetone wipe again after abrasion. Do not touch the surface with bare hands — skin oils are the classic contamination source.
4. Pre-fit dry. Confirm clamp pressure, shim stack, and gap (< 0.2 mm ideal; up to 1.0 mm acceptable for gap-filling AV138 M).
5. Mix and degas (if possible). Stir for 3 minutes, scraping the walls and bottom; vacuum-degas for 5 minutes at 50 mbar to remove entrained air before potting transformer coils or sensor housings.
6. Apply and clamp. A 0.05 – 0.15 mm bond line is the sweet spot. Over-thick layers shrink and crack; under-thick layers starve the joint.
7. Cure. Room-temperature 24 h for shop-floor repair; 60–80 °C oven cure for production line and high-temperature service. Do not load the joint before full cure.
8. Document. For OEM builds, record the batch number, mix ratio by weight, ambient temperature, and cure schedule on the build sheet — same discipline as commissioning a new Siemens SIMATIC or Omron CP1E rack.
