The different types of elastomers have been discussed in section 1.1. Siloxane-based sealants can be organised into two main groups: • One-component RTV silicones mainly used in the construction industry for sealants around windows and doors, in bathrooms, expansion joints between dissimilar materials, etc. • Two-components RTV silicones mainly used for sealing of electronic components and sealed glazing units. Besides the pure silicone sealants, a number of different hybrid sealants in which the siloxanes are blended with other polymers like polyurethanes, acrylics and isobutylene exist. In some of the sealants the siloxanes only account for a small part of the product. Typical one-component RTV silicone sealants consist of the following components (Krogh 1999): • 60-80 % siloxane; • 5-7% cross-linking agent • 20-30 % CaCO 2 filler; • 1-6% silica filler; • 5-20 % drying agents (siccatives); • 0.05-0.1% organotin catalyst. The cross-linking agents are tri- or tetrafunctional silanes containing hydrolysable Si-O or Si-N bonds. Most of the cross-linking agents react either spontaneously with the SiOH groups of the siloxane or with water. Curing of one-component RTV silicones starts when the compounds are exposed to atmospheric moisture during application. Depending on the used crosslinking agent different compounds are formed as cleavage product and will be released during the curing process (see section 1.1). 29
