The methoxy groups of the silane hydrolyze and form strong covalent bonds with the native oxide layers present on ceramics (SiO2) or free (OH) groups on silicon carbide or boron carbide. To improve adhesion at the interface, introducing controlled roughening of the surface is advisable. A solution concentration in the range of 1–5% should provide sufficient effectiveness.

General description
Le (3-glycidyloxypropyl)triméthoxysilane (GPTMS) est un organosilane bifonctionnel comportant trois groupements méthoxy d'un côté et un cycle époxy de l'autre. Les groupements méthoxy se lient bien aux substrats de verre, créant une matrice en 3D. Les groupements époxy réagissent quant à eux avec les amides, les alcools, les thiols et les acides. Le GPTMS est très réactif dans l'eau et il peut être utilisé comme agent de liaison entre la surface de la silice et la matrice polymère.
Application
Prétraiter un acier au carbone avec du 3-(glycidoxypropyl)triméthoxysilane améliore l'adhérence en milieux sec et humide et réduit le taux de décollement cathodique d'un revêtement époxy.

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

I connected GPTMS synthetically to my lipid(APTES), now my lipid cannot be dissolved in chloroform, ethanol and methanol solutions, which was previously dissolved, what solvent should I use?
1 answer-
The solubility of the GPTMS/APTES sample has not been tested, however decreasing the concentration in chloroform may be useful. Other solvents such as oils (see C8267) or a strong base, such as sodium hydroxide, may also be an option. See the link below to a publication that may be of interest:
