Product Information

Full details

The Electrolube Optically Clear Polyurethane Resin (UR5634RP250G) is designed for creators and manufacturers seeking a durable, transparent coating or encapsulation solution for decorative and protective applications. Its key benefit is its water-white clarity and resistance to UV, chemicals, and water, ensuring long-lasting aesthetic appeal and protection. A potential caveat is the need for precise mixing ratios and proper curing conditions for optimal results.

FAQs

What is the mix ratio for this resin?

The resin features a 1:1 by volume mix ratio for ease of processing.

Is this resin suitable for outdoor use?

Yes, it exhibits high resistance to weather and UV, making it suitable for outdoor applications.

What is the primary benefit of this resin's clarity?

Its water-white transparency is ideal for decorative applications and protecting components in LED systems where light transmission is crucial.

Does this product contain hazardous chemicals like IPDI?

No, it is a low hazard material as it does not contain IPDI.

How long does it take to cure?

Curing times depend on ambient temperature and humidity. Refer to the product's technical data sheet for specific curing profiles.

Can this resin be used for flexible applications?

This is a semi-rigid resin. While it offers some flexibility, it is not designed for applications requiring high degrees of pliability or extreme flexibility.

What kind of resistance does this resin offer?

It offers high resistance to weather/UV, acids and alkalis, water, and mould growth.

Troubleshooting

Resin does not cure or remains tacky

Ensure the correct 1:1 mix ratio was used. Verify that both components were thoroughly mixed. Check ambient temperature and humidity, as these can affect curing times. Ensure components were stored correctly and not past their shelf life.

Visible bubbles in the cured resin

Mix components slowly and carefully to minimize air introduction. Allow the mixed resin to 'sweat out' or degas for a period before pouring. Using a vacuum chamber during or after pouring can remove trapped air.

Cloudy or discolored finish

Ensure components were stored properly and are within their expiry date. Avoid contamination during mixing and pouring. Check for moisture in the mixing environment or on the substrate.

Poor adhesion to substrate

Ensure the substrate is clean, dry, and free from dust, grease, or other contaminants. Lightly abrading the surface may improve adhesion on certain materials. Perform a test patch first.

Pros and Cons

Pros

  • Excellent clarity for visual applications
  • High resistance to environmental factors (UV, water, chemicals)
  • Easy 1:1 mix ratio simplifies application
  • Durable, semi-rigid finish protects components
  • Low hazard formulation enhances safety
  • Resistant to mould growth

Cons

  • Requires precise mixing for optimal performance
  • Curing times can vary based on ambient conditions
  • Low viscosity may require containment for intricate designs
  • Not suitable for applications requiring extreme flexibility
  • Two-part systems necessitate careful handling and storage

Setup, Compatibility & Care

Setup:

  1. Ensure both Part A and Part B are stored at room temperature.
  2. Accurately measure equal volumes of Part A and Part B.
  3. Thoroughly mix the two parts using a clean mixing stick, ensuring to scrape the sides and bottom of the container.
  4. Allow the mixed resin to degas if necessary, especially for bubble-free finishes.
  5. Pour the mixed resin into the prepared mold or onto the surface to be coated.
  6. Allow the resin to cure fully according to the manufacturer's recommended time and temperature.

Compatibility:

This resin is generally compatible with most common substrates including plastics, metals, and ceramics. It is recommended to perform a small compatibility test on a non-critical area if unsure.

Care:

To maintain the clarity and integrity of the cured resin, clean surfaces with a soft, damp cloth. Avoid abrasive cleaners or solvents that could potentially damage the surface.
