Experimental Tests of Adhesion of Silicone Sealants within Extreme Weather Conditions

Experimental Tests of Adhesion of Silicone Sealants within Extreme Weather Conditions

Paper in proceedings (conference paper)

This contribution concerns tests carried out to investigate the tensile properties of silicone sealants for use with facade cladding materials. The experimental part of the research is aimed at ascertaining the technical properties of sealants via the cyclic alternation of extension and shrinking, or rather compression, of test specimens in test moulds. For the tests, industrially manufactured neutral and universal silicones were chosen from three different manufacturers. The aim of the research was to discover any differences that might appear in their resistance against alternating maintained extension and compression of the specimens under different temperature conditions, i.e. a high temperature of (70 +/- 2) C and a temperature simulating freezing, i.e. (-20 +/- 2) C. The cladding material used was composite plastic panels (i.e. HPL panels), large-scale ceramic tiles, metal plates (i.e. Corten) and aluminium tiles (i.e. Alubond). The result of the measurements taken is a summary in which effective and unsuitable combinations of sealants and test substrates are outlined, as well as a related proposal for a suitable application technique.
