Silane is not a wetting agent, silane is not a coating!
Silane is a coupling agent used to promote adhesion. |
Silane acts on the surface of minerals (such as glass or ceramic) and also on the surface of organic polymers (such as epoxy, polyester or metacrylate resins) causing a chemical reaction. This reaction is a condensation reaction in the case of mineral groups or, in the case of polymers, it is an addition reaction and/or copolymerization by reaction with terminal groups and grafting with free-radical sites.

• Silanation improves adhesion. |
|
• Silanation improves hydrolysis resistance. |
|
• Silanation increases toughness. |
|
|
• The organo-silane used must be chosen to react with the proper polymer of the post. |
|
• Silane solutions have a limited lifetime. |
|
• The silanation procedure is precise and must be respected: factory silanation with accurate industrial control is the answer. |
|
Q How long is silanation active? |
|
A Silanation is a permanent chemical reaction always active when done. |
|
Q If a post is taken with bare fingers, does it remove the silanation? |
|
A No, but the fingers make a greasy deposit (finger prints). Wipe the post with a tissue and alcohol to clean it. |
|
Q Does sterilisation destroy silanation? |
|
A No, silanation effects remain even after posts have been sterilized. |
