To understand the process of curing and bonding, it's necessary to understand the physical and chemical makeup of both the silicone rubber and the metal substrate during the application and curing process.
How does mechanical adhesion work?
Mechanical adhesion works best when the metal substrate is clean and smooth, but not polished, since large irregularities and impurities such as oil and dust inhibit the connection between metal and sealant.
Is silicone rubber a polymer?
Silicone rubber is a polymer, or repeating chain of molecules. Each link in the chain contains atoms that are free to bond with atoms on the surface of the metal substrate, making the polymer a strong connection that can bend and flex while still adhering to the metal beneath it; a valuable property when external temperatures ...
How to remove silicone from plastic?
You can use a silicone sealant remover to rub off the silicone from the plastic. You’ll also want to have a scraping tool to separate as much silicone as possible. Follow the steps below to remove silicone from plastic: 1 Remove as much silicone sealant as possible from the plastic using a scraping tool. 2 Apply a silicone sealant remover suitable for the plastic to the surface you want to clear using a tube or a sealant gun. 3 After applying the silicone remover, leave it for a couple of hours. 4 The silicone will swell, so when this happens, gently scrape it off the plastic. 5 Wipe the plastic surface clean.
