In addition, organic systems often have a greatly reduced stability when exposed to strong sunlight or otherwise elevated temperatures, which reduces their mechanical performance in the chemical fastening of anchoring elements. In addition, problems can arise in the chemical fastening of galvanized anchoring elements, which can be traced back to zinc corrosion or contact corrosion caused by the chemical fastening means. In the long term, these anchoring elements cannot have sufficiently high loads due to the chemical fastening.
