A new INDEX range manufactured in-house 30 March 2021

INDEX® A Perfect Fixing has started the year with a new catalogue featuring an extensive offering of new products, such as its new range of TH/TF metal anchors for large loads  – manufactured in-house.

The new range consists of nine models with different heads in a wide selection of metrics, diameters and lengths. The anchors are available with two types of coatings – zinc plated and Atlantis C3-H, which is a special coating offering the best protection against corrosion in category C3 atmospheres in accordance with the ISO 9223.

The anchors can be installed with reduced distances between anchors and at the edge of the concrete element, because they use mechanical interference between the thread and the base material to generate a smaller load on the concrete. The anchors can also be installed with just a drill and an impact driver, significantly reducing and simplifying installation time. INDEX® points out it is also not necessary to clean the holes in vertical installations and in roofs and/or floors.

Once installed the anchors are easily removable, making a good solution for temporary installations. They can also be unscrewed for correct adjustment and have up to three approved screw-in depths. The anchors also have optimised threads to guarantee maximum loads, as well as being available in a complete range of diameters.

The new range has also achieved multiple European Technical Assessments, such as in option 1 (ETA – 20/0046) for installation in cracked and non-cracked concrete (C20/25-C50/60); for non-structural redundant systems (ETA 20/0494) in concrete (C20/25) and hollow-core slabs (≥ C30/37); as well as being approved for fire resistance R30 – R120 in concrete.

When can you handle a chemical anchor?

INDEX has also recently incorporated an innovative handling signal system into its MO-PS+ (Styrene-Free Polyester PLUS) chemical anchor, a unique new technology that provides a visual indication of when the product can or cannot be handled.

Thanks to the new formulation, which INDEX mentions is unique on the market, the resin changes colour from blue to grey as the curing process starts. While it is still a shade of blue, the applied stud or rod can be adjusted. Once it turns grey, the adjustment time is over and the curing starts.

INDEX has released an explanatory video on its YouTube channel offering a clear demonstration of the colour change, and the main steps to follow when using this product.

These steps include:

Application: Once the material has been drilled and any debris cleaned away, insert the chemical anchor. If the material is hollow (e.g a hollow brick), it must be installed with a screen.

Adjustment time: While the MO-PS+ is still blue, the rod can be adjusted to be correctly set in place. The adjustment and curing times are detailed on the product label.

Wait for the curing time: When the colour is completely grey, the adjustment time is over, and the curing starts. The time will vary depending on the ambient temperature, so it is advisable to follow the curing times printed on the product label.

Apply the load: After the curing time, the load can be applied.

The MO-PS+ chemical anchor, with EOTA approval for all types of non-cracked concrete, masonry and all concrete applications, as well as A+ environmental certification and LEED tested, guarantees maximum performance for medium high loads – withstanding maximum loads of 6,600kg in concrete and 115kg in hollow brick. It is particularly suitable for fixing stone cladding, restoring façades and fixing supports for air conditioning, signs, boilers, shelves, etc.

The new MO-PS+ is part of the wide range of chemical anchors offered by INDEX.
