Evonik (formerly Degussa AG) F8815, organic silane coupling agent Dynasylan F8815, improved water-based fluoroalkyl siloxane Overview:

Dynasylan ® F8815 improved water-based fluoroalkyl siloxane is developed and produced by Evonik Degussa AG, and is a water-based, fluorinated functionalized oligomeric siloxane, It can be used as a surface modifier to treat substrates containing oxygen, carboxyl, and hydroxyl groups, including ceramics, natural fiber fabrics, such as cotton and leather products.
 
 Dynasylan ® F8815 modified waterborne fluoroalkyl siloxane is a slightly yellow and slightly suspended liquid. The product can be miscible with water in any proportion.
 
 Dynasylan ® F8815 Improved Water Based Fluoroalkyl Siloxanes Functionality:

 Dynasylan ® F8815 modified waterborne fluoroalkyl siloxane is a three functional organic compound: active silanol groups can form chemical bonds with inorganic substrates. The substituent functionalized with amino alkyl provides good water solubility. Siloxanes with fluoroalkyl functional groups, once uniformly treated on the substrate surface, will introduce very low surface energy.
 
 By using commercially available fluorocarbon compounds for coating, a similar water oil dual hydrophobic treatment effect can be achieved. And Dynasylan ®F8815 The advantage is that it can form chemical bonds with the substrate. Simultaneously, cross-linking occurs horizontally to form 2 Peacekeeping 3 The network structure of dimensions.
 
 Therefore, even at very low concentrations of Dynasylan ® F8815 improved water-based fluoroalkyl siloxane can also form stable coatings that are resistant to chemical corrosion, heat, and mechanical friction.

Evonik (formerly Degussa AG) F8815, organic silane coupling agent Dynasylan F8815, improved water-based fluoroalkyl siloxane application:

 The application of Dynasylan ® F8815 modified water-based fluoroalkyl siloxane is very extensive. For example:
         · Sol gel/ Additives in Hybrid Systems
         · Modifiers for paints and varnishes
         · Leather hydrophobic treatment
         · The water oil dual hydrophobicity of fabrics, also known as "easy to clean" treatment
 
 Dynasylan ® F8815 Improved Water based Fluoroalkyl Siloxanes Process:

 Using Dynasylan ® Before treating F8815 modified water-based fluoroalkyl siloxane, the surface of the substrate must be thoroughly cleaned and degreased!
 
 Dynasylan ® F8815 modified waterborne fluoroalkyl siloxane can be miscible with water in any ratio. The product should be thoroughly mixed before use to ensure uniformity. The specific usage concentration varies depending on the expected application effect. The diluted standby solution can generally be stored for a few days.
 
 For some fabrics such as cotton products, 5-15 wt.% can be used Dynasylan's ® Soaking or spraying of F8815 modified water-based fluoroalkyl siloxane in aqueous solution. The soaking time, which is the general reaction time, is 0.5-10 Wait for minutes.
 
 You can also use Dynasylan ® F8815 improved water-based fluoroalkyl siloxane is polished onto leather products to achieve excellent hydrophobic effect.
 
 A thin layer of polysiloxane coating and its unique water repellent properties form within a few hours at room temperature. Crosslinking can be achieved through a certain degree of heating (80~150 Accelerated formation at ℃. The properties of water oil dual hydrophobicity can be evaluated by measuring the static contact angle.
