Product - MR. JO Lami-HV

Description

MR. JO Lami-HV is a two-part epoxy system. It has medium viscosity. It is great for metal models and electrical parts. Also, it works with carbon fiber, glass fiber, and CSM. The resin spreads easily. It sticks things together very well. Since it is solvent-free, it is safe to use. So, it is perfect for lamination, insulation, and repair work.

• Color: Clear
• Pot life @25°C: 100-150mins
• Mixing Ratio: 100:10 PBW
• Mixture consistency: Low Viscous liquid
• Optics: Transparent

• Glass fiber laminates
• Lamination tools
• Composites

• Surfaces should be freed from laitance and dust by sand-blasting. In case sand blasting is not possible, thorough abrading with a hard wire brush should be preferable
• Suitable degreasing agent should be used to remove any grease, oil or traces on the surface.

• Take small quantities of laminating resin and hardener parts by weight as recommended.
• Mix the two components together thoroughly for at least 2 minutes so as to achieve uniform mixing and thorough consistency of the mix.
• Lay the 100-650 GSM of glass fiber/carbon fiber on the surface to be covered, apply 2 or 3 coats of the mixture again. The laminating resin can be poured directly from the mixing can onto the fiberglass/carbon fiber and spread around with the paint roller/brush.
• Allow it to cure for the given cure time to get the desired results.
• Apply casting system.

A1. MR. JO Lami – HV is a high-viscosity epoxy resin system for:

• Hand lay-up of fiber reinforcements (glass, carbon, chopped strand mat)
• Laminated moulds and composite parts
• General-purpose FRP fabrication

A2.

• Thicker consistency than LV
• Better for controlled applications or vertical surfaces
• Less prone to dripping Both offer similar mechanical and chemical resistance after curing.

A3. 100:10 by weight (resin : hardener). Mix thoroughly until uniform.

A4. Yes — it is comparable to Araldite LY556 with Hardener HY951, widely used in FRP laminates and tooling.

A5. Choose HV if:

• You’re working on vertical or angled surfaces
• Need more control in resin flow
• Prefer a stiffer application for detailed layups

A6. Works well with:

• Glass fiber (Woven & CSM)
• Carbon fiber
• Aramid fabrics
• Natural fibers (if pre-coated or pre-wetted)

A7.

• Pot life: ~30–40 minutes
• Handling strength: ~6–8 hours
• Full cure: ~24 hours at 25°C

A8. Yes. Lami – HV is suited for rigid patterns, jigs, mould shells, and tooling when paired with reinforcement layers.

A9. Yes — use epoxy-safe pigments, fillers, or thixotropic agents as needed.

A10. Apply by brush or spatula, especially when working with chopped strands or complex curves. HV stays in place well.

A11. Yes, when reinforced with fabrics, it yields strong, durable, chemically resistant laminates.

A12. Yes — once cured, it can be sanded, drilled, or milled for finishing.

A13. Like most epoxies, some yellowing may occur over time. Apply UV-protective coatings for outdoor or exposed use.

A14. Yes. Make sure to pre-seal porous materials to prevent air bubbles or over-absorption.

A15. 12 months when stored in sealed containers under cool, dry conditions.
