Properties & Reactivity
In many sol-gel applications D-25 is partially hydrolyzed to form a preproduct that can be further crosslinked using temperature. This pre-hydrolysis is often made in conjunction with methyltrimethoxysilane or other organofunctional silanes, silicic acid esters, or even an aqueous silica sol.
D-25 reacts faster with water than phenyltriethoxysilane.
Application and performance
D-25 is used to modify the suface of inorganic fillers such as wollastonite and aluminum trihydroxide. It makes the surface of these inorganic fillers more hydrophobic and thus increases their dispersability in mineral-filled polymers. D-25 is especially suited for polymers that are processed at elevated temperatures. D-25 reduces the viscosity of the polymer melt.
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.
