⚙️ Applications
🛠️Glass & Carbon Fiber Laminates
Reliable wetting and strong interlaminar strength for multi-layer layups.
🧰Composite Mold & Tooling Production
Ideal for manufacturing negative molds, stencils, and laminating tools.
🚤Marine & Boat Hull Repairs
Long open time and high strength make it perfect for intricate marine applications.
🚗Automotive & Aerospace
Used in body panels, air ducts, fairings, and other precision composite parts.
🧱Electrical Insulation & Repairs
Suitable for potting, encapsulation, and repairs of insulators and electrical assemblies.
🧱 Surface Prep Recommendations
- Surface must be free from laitance, dust, oil, or loose paint
- High-pressure water blasting or wet grit blast preferred
- Optional: 15% HCl etching if other methods not feasible
- Drying not essential — can be applied on damp concrete
🎯 Why Choose MR. JO Lami-HV?
- Consistency You Can Trust
Whether you’re creating one-off prototypes or recurring production tools, MR. JO Lami-HV offers batch-to-batch consistency and excellent workability. - High Performance, No Compromise
Designed to resist mechanical and environmental stressors, the system holds up under repeated use and varied conditions. - Ideal for Vertical Surfaces
Thicker viscosity helps in maintaining resin position in hand laminations, reducing drips or runs on inclined or curved surfaces. - Professional-Grade Output
Offers glass-like finish when properly cured — ideal for parts where both appearance and performance matter.
🧼 Processing Tips
- Always mix resin and hardener in the prescribed ratio (100:10 PBW) thoroughly.
- Use a roller or brush to ensure even wetting of reinforcement fabrics.
- Degas or allow to settle before layup to reduce entrapped air.
- Apply in layers if thicker sections are required to avoid exotherm.
🔒 Storage & Safety
- Store in a cool, dry place between 18–25°C.
- Ensure containers are tightly sealed after use.
- Use PPE (gloves, goggles) during application. Refer to SDS for details.
MR. JO Lami-HV is your reliable partner for precision lamination, composite repair, and mold making — from boats to body panels, insulators to industrial tools. When you need a smooth-finish, durable epoxy with easy application and versatile performance, trust MR. JO to deliver the strength to bond and the power to protect.
