Product - MR. JO Tecbond – CLR20

Description

Mr. JO Tecbond – CLR20 is a two component thick epoxy adhesive. Also, it works well for automotive and marine use. You can mix this two-component adhesive with a 100 PHR ratio. It has a 20 minutes pot life, so you can apply it easily and precisely. The adhesive is crystal clear and gives clean and shiny finish. Also, it bonds strongly to non porous surfaces like metal, glass, stone, and plastic. Its versatile design handles tough environments and demanding tasks. This makes it a reliable choice for industrial and general applications.

• Color :- Clear
• Pot life :- @25'C 15-25 mins
• Mixing Ratio :- 100:100 PBW
• Mixture consistency :- Clear think flowable liquid
• Optics :- Transprent

• Glass bonding
•  Engineering application
•  Handicraft

• 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 Part A & Part B in ratio 100:100 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-CLR20 is a clear, fast-setting epoxy adhesive designed for applications that demand aesthetic bonding and quick handling, particularly in

• Glass and acrylic fixtures
• Clear furniture joints
• Precision craft and hobby work

Repairs where transparency and heat resistance are important

A2. Though all are clear epoxies:

• CLR20 cures faster (pot life ~20 min)
• CLR20 has a different chemistry, providing better heat resistance and mechanical strength
• CLR30/40/60 are slower setting and optimized for ease and extended working time, but not ideal for high-temp or high-stress environments

A3. Choose CLR20 if you need:

• Fast curing (20 min pot life)
• Excellent optical clarity
• Higher thermal stability
• A strong, rigid bond for small or delicate components

A4. Yes, it’s perfect for small-scale industrial assembly, decorative hardware, optical-grade bonding, and anywhere a clear, strong, fast-set adhesive is preferred.

A5. Mix 100 parts resin to 100 parts hardener by weight (1:1 PBW). CLR20 has a medium-flow viscosity, suitable for spreading, thin-layer bonding, or gap filling up to ~0.5 mm.

A6. Pot life: ~20 minutes at 25°C. Initial handling strength: within 1–2 hours. Full cure: 24 hours at room temperature (faster at elevated temperatures).

A7. Yes. It bonds:

• Wood
• Stone and ceramic
• Metal and composite materials Provided surfaces are clean and prepped.

A8. It has moderate flow, so use caution. For vertical applications, consider MR. JO Tecbond-VCL.

A9. MR. JO Tecbond-CLR20 cures to a crystal-clear, glossy finish, with minimal ambering under indoor conditions.

A10. Yes. CLR20 offers better temperature stability than typical clear epoxies — suitable for parts exposed to warm surfaces, mild heat zones (~60–70°C).

A11. It’s best used in thin bond lines or tight joints. For larger gaps or structural fills, a thickened or paste-grade epoxy is recommended.

A12. Absolutely. After full cure, it can be sanded, buffed, or overcoated with PU, lacquer, or varnish.
