KBM-903, 3-aminopropyltrimethoxysilane, is one of the most versatile coupling agents, having a broad range of applications in composites, coatings, adhesives, sealants, and elastomers. Similar in structure and function to Shin-Etsu’s KBE-903, 3-aminopropyltriethoxysilane, the three hydrolyzable methoxy groups of KBM-903 are slightly more reactive than the three ethoxy groups of KBE-903. As such, this product may lead to improved interaction between the inorganic and organic components of some systems. If a longer shelf life or another aspect of increased hydrolytic stability is critical to a given application, KBE-903 may be more suitable. In most applications, this product is an appropriate replacement for KBE-903 and has the added benefit of lower weight loss upon hydrolysis.
Shin-Etsu Silicones produces silicones and silicone products for the Paints and Coating Industry. They provide first rate silicone compounds to develop and increase the reliability and all around performance of a product. One such product type, Silane Coupling Agents, are used as a mediator that helps improve and support bonds between inorganic and organic materials. This allows for surface modification and resin modification to take place. It also aids in the increased adhesion and the enhancement of the mechanical durability of composite materials.

Lists combine the ease of Bookmarks with the versatility of Tags. Instead of one collection of bookmarked items, create as many collections, called "Lists," as you need.
Find the link to your List page in the user menu.
All Tags have been converted to separate Lists, and your bookmarked items have been saved to a "Bookmarks" List.
When you click the Add to List button, a dropdown of your existing Lists appears. Click the List name to which you want to add this product or formula.
You can also create a new List. Simply click "Create a New List" and enter a name.
When you define a new List, the current item is automatically added to it. You can add a product or formula to as many Lists as you need.
Easily see which Lists this item appears in, and quickly go to that List from the links that appear on the page.
