TALULOCK® is a next-generation, DNV-approved, epoxy-based resin socketing system for wire rope.

Introduction

TALULOCK® is a new and improved resin for socketing of wire ropes (and various synthetic ropes*), with a better adherence to the wires which gives a stronger grip where needed. Like other resins, it is to be poured into sockets, or end stops where the wire rope has been broomed and cleaned.

The resin fulfills the performance criteria of EN 13411-4 and ISO 17558. Furthermore, it is fully approved by DNV to meet the requirements of DNV-OS-E304 and DNV-CP-0095. This means that the resin is approved for usage on steel wire ropes for offshore mooring. With better sub-surface properties compared to present alternatives on the market, the TALULOCK® resin is well suited for usage in the most demanding conditions.

This high performing resin contains at least 10% renewable material which fully hardens without affecting the resin’s durability. Any leftover cured material should be treated as combustible waste.

Furthermore, TALULOCK® is free of solvents that are hazardous for the operators to the extent that we do not need to recommend using a mask or mixing/pouring in a ventilated area, simply use appropriate clothing, gloves and eye protection. Always follow the recommendations in our Safety Data Sheet.

Without the self-hardening properties that today’s solutions have, TALULOCK® can be stored for up to 2.5 years (30 months) in up to 30 degrees Celsius. Minimizing the number of out-of-date kits that has to be thrown away. Our solution can also be transported without restrictions due to its content. Without any flammable content it is possible to ship via air freight, and with its low requirements for storing it can easily be shipped on slower vessels without cooling and the risk of expiring the products.

BENEFITS:

• No solvents affecting operators and the NO cancerogenic content!
• Superior performance in small end stops applications with less shrinkage and better grip to the individual wires.
• Longer and less demanding storage enables customers to keep TALULOCK® in stock to be able to get orders on short notice. TALULOCK® has a shelf life of 30 months from the date of manufacture, ensuring extended usability and reliability throughout this period.
• TALULOCK® is NOT flammable, which means it can be express transported, without having to maintain a specific temperature during the transport.

Instructions

1    Prepare the wire rope and socket for termination. Follow the general practices outlined in EN 13411, or use your company’s internal procedures applicable to the resin being used.

2    Make sure you are wearing appropriate gloves and eye protection, that you have suitable protective clothing on, and that an eye-wash station is accessible before starting to mix the TALULOCK®.

3    Mix TALULOCK® part A and part B by pouring all of the content from part B into the tin can. Start mixing using a flat item without rounded edges to allow for proper mixing. Mix the contents for 2 to 4.5 minutes. The solution should become easier to stir over time as the two components are mixed.

4    Pour the contents of the tin can slowly into the socket. Aim for the side wall to allow the resin to enter the bottom of the socket on one end to avoid trapping air in the bottom. Fill the socket/end stop all the way up to the edge or marking (if there is a mark), top up as needed if the resin sinks down after pouring (indication that air has been trapped).

5   Allow the resin to gel and harden. The time needed for this depends on the surrounding temperature, the volume of resin in the socket and the amount of metal (socket and wire rope) and its ability to transfer heat and cool down the reaction. Normally the resin gels in about 20 to 40 minutes; the time to a successful scratch test is temperature-dependent (for example, around 110 minutes at 20 °C).

6    The curing process will continue for several hours thereafter but with a diminishing effect on the properties. After a successful scratch test, allow the resin to cure for a further period at least equal to the time that elapsed before the test was performed. Only then may the rope be put into service.
