🔧 How to Use
✅ Surface Preparation
- Ensure surfaces are clean, dry, and oil-free.
- Use solvents like IPA or acetone to clean the bonding area.
- Slight abrasion on smooth surfaces (glass/metal) improves bonding.
⚖️ Mixing Instructions
- Mix equal weights (100:100 PBW) of resin and hardener thoroughly for 2–3 minutes.
- Use a clean container and avoid whipping air into the mix.
- Scrape the sides and bottom while mixing to ensure uniformity.
🖌️ Application
- Apply evenly on one or both bonding surfaces.
- Press and align components within 35–45 minutes (pot life window).
- Clamp lightly if needed to ensure proper bonding pressure.
- Allow full cure at room temperature (24 hrs) or accelerate at low heat (40–50°C).
⚠️ Precautions & Cleanup - Work in a well-ventilated area.
- Use gloves and avoid skin contact.
- Clean tools and spills immediately using acetone or IPA before the adhesive cures.
- Do not mix more material than can be used within pot life, especially in large volumes due to heat build-up.
🧠 Ideal For - Glass & acrylic product makers
