product description

structural formula:

empirical formula: c8h20o4si

molecular weight: 208.33

cas no.: 78-10-4

chemical name: tetraethylsilane, tetraethyl orthosilicate

properties

good penetration, due to small molecular size.

inorganic binder, uv stable.

used for sol-gel processes in combination with other alkylsilanes such as d-150 silane.

reactivity

tetraethyl orthosilicate (teos) will react with moisture to form a silica-gel like binder and ethanol byproduct which evaporates.

technical data

application and performance

d-130（si28）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.

for the manufacture of sealant materials rtv-2, d-130（si28）can be used as a cross-linking agent.

on glass and plastic lens materials, d-130（si28）silane provides a scratch-resistant, hard-coat to the finish.

product safety, handling and storage

customers considering the use of this product should review the latest material safety data sheet and label for product safety information, handling instructions, personal protective equipment if necessary, and any special storage condition required. the “best use before end” date of each batch is shown on the

product label. storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. in this case however, the properties required for the intended use must be checked for quality assurance reasons.
