Descripción general

El (3-glicidiloxipropil)trimetoxisilano (GPTMS) es un organosilano bifuncional con tres grupos metoxi en un lado y un anillo epoxi en el otro. Los grupos metoxi se unen bien con sustratos de vidrio creando una matriz tridimensional. El grupo epoxi es reactivo con amidas, alcoholes, tioles y ácidos. El GPTMS es muy reactivo en agua y puede utilizarse como reticulante entre la superficie del sílice y la matriz polimérica.[1][2][3]

Aplicación

El GPTMS se emplea mucho como precursor del sílice. El GPTMS solo con tetraetilortosilicato (TEOS) puede mezclarse con quitosano para utilizarse como relleno de armazones de polímeros para ingeniería de tejido óseo.[4] También puede recubrirse en la superficie de aleación de aluminio para proteger de la corrosión.[5] El GPTMS puede utilizarse para funcionalizar (envolver) natotubos de carbono de pared múltiple (MWCNT), que pueden utilizarse como un refuerzo en los nanocompuestos de matriz epoxi.[2]
El pretratamiento del acero de carbono con 3-(glicidoxipropil)trimetoxisilano potencia la adhesión seca y húmeda mientras que reduce la tasa de desvinculación catódica de un recubrimiento epoxi[6]

Questions

1–9 of 9 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. 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

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  4. 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

    1. 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:
