Product - MR. JO Tecbond – LV50

Description

MR. JO Tecbond – LV50 provides strong and reliable bonding for brushes and rollers. It uses a 50 PHR ratio and a solvent-free formula, making it both effective and eco-friendly. Also, its low viscosity makes it easy to apply, helps it flow smoothly, and lets it soak in deeply. As a result, it forms a tough and long-lasting bond. Whether you are working on detailed brush jobs or large-scale production, you can count on it for consistent, high-quality results. Also, it lowers harmful emissions and helps keep your workspace cleaner and safer.

• Cures at Room Temperature
• Excellent Adhesive strength
• Good mechanical properties
• Clear appearance
• Bonds a wide variety of materials in common use

• Brush bonding
• Paint roller manufacturing
• Cracks and gap sealing
• Potting

• The mixture should be applied on a clean, rough and dry surface. This should be achieved by suitable mechanical and chemical means such as sandblasting Wire brushing or chemical etching. Suitable degreasing agent should be used to remove any grease, or oil traces on the surface.

• Use Jpoxy Part-A & Part-B in ratio 100:50 pbw. Mix the two components in small batches thoroughly for at least 2minutes. Apply the mix directly or using proper spatula to the pretreated surfaces.
• The joint components should be assembled as soon as the adhesive has been applied.
• Allow the material to cure for at least 24 hours before putting to use.

A1. MR. JO Tecbond – LV50 is a low-viscosity epoxy adhesive designed primarily for brush bonding (fixing filaments into ferrules during paintbrush manufacturing), and is especially well-suited for:

• Automated brush manufacturing lines
• Precision-controlled dosing
• Low-exotherm requirements

It also serves well in general-purpose bonding, encapsulation, and potting applications where a flowable system is needed.

• LV50 uses a 100:50 PBW mix ratio, making it easier to measure and mix manually or via automated dispensers
• It generates lower exotherm compared to 100:10 systems, reducing the risk of yellowing or thermal distortion
• Offers similar flow and strong anchoring capability, with greater formulation stability

• The 2:1 mix ratio simplifies integration with automated mixing and dosing systems
• It maintains consistent viscosity during pot life
• It reduces waste and improves control in mass production environments

A4. Absolutely. Its low viscosity and low exotherm make it ideal for:

• Encapsulation of small electrical components
• Filling narrow gaps or voids
• Bonding in tight assemblies or where minimal shrinkage is needed

• Mix Ratio: 100 parts resin : 50 parts hardener by weight (100:50 PBW)
• Pot Life: ~50–70 minutes at 25°C
• Full Cure: 24 hours at room temperature; faster with mild heat

A6. Yes. Once cured, it offers a strong, rigid bond with excellent grip in the ferrule. It performs comparably to other brush bonding products but with added ease of use and consistency.

A7. Lower exotherm:

• Reduces internal yellowing
• Minimizes thermal stress on filaments or ferrules
• Allows bulk batching or deeper pours without overheating

A8. Yes, MR. JO Tecbond – LV50 is flowable and self-leveling, which aids:

• Smooth filling of brush bases
• Even coverage in potting and gap filling applications

A9. It typically cures to a clear to slightly translucent rigid finish. In thinner sections, it remains more transparent.

A10. Yes. Once cured, it has moderate water resistance and can withstand temperatures up to ~60–70°C, making it reliable for standard use cases.

A11. Yes. After full cure, it can be machined, sanded, or painted, similar to other rigid epoxy systems.

A13. Yes. Although optimized for automation, LV50 can be easily used with manual mixing and filling tools in small or custom production runs.
