OUKAMU's high-quality resin products provide excellent value for money, offering long-lasting performance and reduced maintenance requirements.

How to Apply Resin Compound in Wiring Projects?

Proper application of resin compounds is crucial to ensure their effectiveness and longevity. Here's a step-by-step guide to applying resin compounds in electrical wiring projects:

Preparation

Before applying the resin compound, proper preparation is essential:

- Clean the cable ends thoroughly, removing any dirt, grease, or moisture.

- Strip the cable insulation as required, ensuring clean and even cuts.

- If using a mold or casing, ensure it's clean and properly positioned.

- Gather all necessary tools and materials, including the resin compound, mixing equipment, and personal protective gear.

OUKAMU provides comprehensive guidelines and support to ensure proper preparation for their resin-based products, maximizing the effectiveness of the application process.

Mixing the Resin Compound

Most resin compounds come in two parts that need to be mixed before application:

- Follow the manufacturer's instructions for the correct mixing ratio.

- Use clean mixing tools and containers to avoid contamination.

- Mix thoroughly but avoid introducing air bubbles into the mixture.

- Be aware of the pot life (working time) of the mixed resin and plan accordingly.

OUKAMU's resin compounds are formulated for optimal mixing and application, with clear instructions provided to ensure consistent results.

Application Techniques

The application method may vary depending on the specific product and application:

- For pourable resins, slowly pour the mixture into the mold or casing, ensuring even distribution and complete coverage.

- For thicker compounds, use a spatula or specialized tool to apply the resin evenly.

- In confined spaces, consider using injection methods to ensure complete filling.

- Remove any air bubbles by gently tapping or using a vibration technique if recommended.

OUKAMU's innovative branch cable technology often incorporates user-friendly application methods, simplifying the process for installers.

Curing and Finishing

After application, the resin compound needs time to cure:

- Follow the manufacturer's recommendations for curing time and conditions.

- Protect the curing resin from dust, moisture, and extreme temperatures.

- Once cured, inspect the joint for any imperfections or voids.

- If necessary, apply additional resin or perform finishing touches as per the product guidelines.

OUKAMU's resin compounds are engineered for optimal curing, ensuring reliable and long-lasting connections in various environmental conditions.

Safety Considerations
