ISOTERMIA

Bossong injected anchors with sock and Presstec grout with GBOS bars. Stainless steel bars fully threated. Stainless steel smooth bars. Couplers, turnbuckers, nuts, standard end and architectural end plates.

Bossong plastic sleeves with thread ends for continuous protection system; nylon insulation washer; metallic pipe fittings drilling machine/BOS TP plastic sleeves.

Highadhesion epoxy resin for heavyduty fastenings for use in different base materials as concrete, solid masonry and wood. This Bossong resin can be used also with wet concrete and flooded hole including underwater fixing (reduction of the recommended loads of 20%). Suitable for electrically insulated fastening. It has longterm resistance to hydrolysis. Excellent for applications with reinforced bars. Thixotropic consistency. The resin, due to its strong adhesion value and the ease with which it penetrates holes and hollow areas, permits secure fixing without expansion and so without stresses in the base material. It does not need premixing, the resin and hardener are only mixed during extrusion in the special mixer. It can also be used for repair and refilling. SERVICE TEMPERATURE RANGE Between 40°C /+ 40°C with T°max long period of 24°C and 40°C/+80°C with T°max long period of 50°C (ambient temperature after installation).

There are certainly technical and theoretical reasons determining whether an anchorage should be realized with resin or grout. However, in the practical application it is not so easy to define such limit, because of many factors, such as the compatibility with the original materials or simply feasibility problems during the execution. Significant parameters for choosing the type of anchors are type of substrate anchorage length hole diameter setting time and fixing mode waiting times for the loading of the anchorage The thixotropic consistency of the resin, that is useful to prevent from excessive spreading in the interstices of historical buildings, complicates the deep extrusion stage and limits the anchorage length in comparison with the application where the injection is realized with grouts.
