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

Introduction

TALULOCK® is a new and innovative two-component epoxy resin for socketing wire ropes, with stronger adherence to individual wires for a stronger grip where it is needed most. Like other resins, it is poured into sockets or end stops where the wire rope has been broomed and cleaned.

TALULOCK® meets the performance requirements of EN 13411-4 and ISO 17558 and is type-approved by DNV under certificate no. TAK00002SF, in compliance with DNV-CP-0095 and DNV-OS-E304. This means it is approved for use 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.

Applications

• Offshore mooring and subsea lifting
• Crane, hoist and heavy-lift rigging
• Industrial and construction wire rope terminations
• Small end-stops and precision assemblies
• Marine, aerospace and entertainment rigging

Operator safety

TALULOCK® contains no carcinogenic constituents and no solvents that require respiratory protection under normal use. Respiratory protection is not required for routine mixing and pouring in a well-ventilated area. Wear suitable gloves, eye protection and protective clothing, and make sure an eye-wash station is accessible. Always read the Safety Data Sheets in full before handling the product; they take precedence in all matters of safety. In many countries, operators of two-component resin systems must complete certified safety training, so check your local requirements.

Environment

At least 10% of the formulation comes from renewable raw materials, without compromising durability. Fully cured TALULOCK® can be disposed of as combustible waste; uncured product must be disposed of as hazardous waste in line with local regulations.

Storage and transport

TALULOCK® has a shelf life of up to 30 months at storage temperatures up to 30 °C, with no need for cold storage or temperature-controlled shipping. That means fewer expired kits and the flexibility to keep stock for short-notice orders. The resin component is non-flammable, making TALULOCK® better suited for air freight and express shipping.

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.
