🧽 How to Use MR. JO Tecbond – GSN
✅ Surface Preparation
- Ensure surfaces are clean, dry, and free from oil, grease, rust, or dust.
- Roughen smooth surfaces slightly for better adhesion.
- Wipe with IPA or acetone before bonding.
⚖️ Mixing Instructions
- Mix resin and hardener in 100:80 PBW ratio thoroughly for 2–3 minutes.
- Use a flat stirrer, not a brush, to avoid air entrapment.
- Only mix what can be used within the pot life.
🎯 Application
- Apply on one or both surfaces depending on the bond area.
- Spread evenly using spatula, brush, or dispensing system.
- Clamp or hold for at least 4–6 hours for optimal bonding.
🕒 Curing Time
- Touch dry: ~6–8 hours at 25°C
- Functional cure: ~12–16 hours
- Full cure: 24–36 hours
- Post-curing (optional) at 50–60°C improves final strength.
⚠️ Precautions & Best Practices
- Do not thin with solvents. Use as-is.
- Avoid moisture during application.
- Clean spills and tools immediately using IPA or acetone.
- Store unmixed components in cool, dry conditions (preferably below 30°C).
- Keep out of reach of children and use in a well-ventilated area.
