XIAMETER OFS-6697 Silane

Description

Tetraethyl orthosilicate (TEOS) for the consolidation of construction materials such as stones in buildings or monuments

Tetraethyl orthosilicate (TEOS) will react with moisture to form a silica-gel like binder and ethanol byproduct which evaporates. The siloxane resin formed is a very resistant inorganic binder to acid rain. Due to the low viscosity it can reach up to 10-20cm penetration depth in very porous substrates.

Features

• Pure grade (>99%)

• Good penetration, due to small molecular size

• Inorganic binder, UV stable BENEFITS

• No aesthetical change to the substrate

• Water vapor permeability is maintained

• Can be used as crosslinker

• Used for sol-gel processes in combination with other alkylsilanes such as XIAMETER® OFS-6070 Silane

Applications

• XIAMETER OFS-6697 Silane pure silane that can be applied neat, diluted or as part of a formulated product. Applied to natural stones or other construction materials, it forms a silica-gel like binder (SiO2) that increases the substrate strength.

• Polymerization of silicone resins for use in paints and other surface modification applications

• Intermediate for sol-gel process
