silicone coatings on plastic

Hey guys,

I am looking all over for some info on silicone spray coatings for plastic. Like the kind you find on iPhone cases. Usually its a silicone spray applied to an injection molded part.

basically i am just looking to learn about the process and the capabilities, but cant find much. anyone have any good resources for this?


If it is sprayed on, its typically referred to as soft touch paint and is a post process.

If it is actually a TPE its called over molding and is part of a two stage molding process.

TPE is thermoplastic elastomer, and you can get a good sense of the overmolding process hereā€¦
