- What silane coupling agent/adhesion promoter should I use?
- Silanes contain dual functions, an organo reactive group for polymers and hydrolyzable groups for inorganics or metal oxide substrates. Therefore, silanes can provide covalent bonds at the interface between polymers and substrates, ultimately enhancing adhesion.

- I have a non-siliceous surface, does that effect what silane I should use?
- The optimum performance of silanes is associated with siliceous substrates which provide hydrolytically stable oxides; however, the use of silanes has been extended to metal substrates or plastics. Therefore, the effectiveness and strategies for bonding to these less favorable substrates vary. The link contains detailed information.

- How do I apply a silane on my surface?
- Silanes can be applied with various methods such as solution treatment or bulk deposition for particulates, or chemical vapor deposition when a monolayer deposition is desirable. For detailed information please see the link.

- Should I clean/prepare the substrate before I apply the silane? If so, how?
- Surface contaminations such as dirt or oils can be removed with organic solvents or special washing solutions. The key for surface preparation is to generate as many hydroxyl groups as possible to improve bonding.

- What are the differences among the various hydrolysable groups, i.e. Alkoxys, Halogens, and Amines?
- In selecting hydrolyzable groups you should consider reactivity, by-products, safety, and your method of treatment. For example, alkoxy functional silanes are an environmentally friendly product because the by-product is alcohol; however, the reactivity is relatively slow.

- What are dipodal silanes and why should I use them?
- Dipodal silanes contain hydrolyzable groups at the terminal positions of the molecule. Functional dipodal silanes and combinations of non-functional dipodal silanes with functional silanes have significant impact on substrate bonding, hydrolytic stability and mechanical strength of many composites systems.

- How do I make a surface hydrophobic, hydrophilic, or oleophobic?
- Silanes can form covalent bonds on inorganic and metal substrates and leave organic groups on the surface. Organic groups can be hydrophilic moiety, i.e. PEG modified or OH modified silanes or hydrophobic moiety, i.e. alkyl silanes or oleophobic moiety, i.e. fluorinated alkyl silanes.

- What is the mechanism of silane – surface modification reaction?
- What is the hydrolytic stability of a silane solution?
- Hydrolytic stability can be viewed two ways. First, hydrolytic stability of the silanes themselves. The concepts can be directly related to the reactivity, hydrolysis rate and condensation rate. Second, hydrolytic stability of covalently bonded silanes on substrates. Dipodal silanes can improve the stability on substrates.

- What is the thermal stability of a silane coupling agent?
- You currently don’t manufacture the material that I need, can you custom synthesize the material for me?
- Go to “Contact Us” on the main menu and select “Custom Synthesis”. Enter the name, C.A.S. number, or draw the desired molecule, then enter all of the required information and submit.
