一般描述

甲氧基三甲基硅烷(MTMS)作为一种甲硅烷基化剂,主要用于提供高水接触角和低表面能量的疏水表面涂层。[1][2]

应用

已经研究了甲基三甲氧基硅烷(MTMS)对二缩水甘油基双酚A型环氧树脂的化学修饰效果。1它被用于在处理HF/吡啶时用MTMS淬灭实验室器皿。{90}
超疏水再生聚乙烯对苯二甲酸酯(rPET)气凝胶可使用rPET纤维和聚乙烯醇(PVA)制成并可涂覆在MTMS上。[3]双酚A型环氧树脂(环氧树脂)上的MTMS还通过将变色效果降低45%显示其耐紫外线老化性能。[4]

Questions

1–2 of 2 Questions  
  1. 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

  2. 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
