Title: USE OF DEFINED SYNTHETIC RESINS FOR FASTENING SCREWS AND SIMILAR ANCHORING MEANS, ASSOCIATED METHODS AND SYNTHETIC RESINS
Abstract:
Use of liquid to pasty multiple-component synthetic resin systems which cure during use for fixing fastening elements in a substrate, wherein a multiple-component synthetic resin system which is liquid to pasty at ambient temperature is introduced into at least one hole after or during mixing of its components. After waiting until it is sufficiently cured, at least one fastening element is driven into the resulting synthetic resin mass. The invention also relates to methods comprising said use and multiple-component synthetic resin systems. The systems comprise certain parameters, like a displaceable volume of 0.1 to 40 Vol.-%, a gel time of 5 to 65 seconds and a mean viscosity of 1000 Pa-s or lower before hardening, wherein one of the components of the multiple component synthetic resin system has a viscosity of at least 30 Pa* s, and a thixotropic index in the range of 4 to 10, and in the cured final state a cross-linking density based on a cross-linking index of 2.3 or higher and the associated multiple component plastic system and associated methods.
