Why SILISKIN?
SILISKIN is a silicone post-treatment technology developed by COP to improve the functionality of silicone parts.
Main objective: to optimize the surface condition to meet real-world uses, particularly in medical and technical applications.
What SILISKIN does:
- adheres to LSR, RTV and HTV silicone surfaces,
- reduces the coefficient of friction,
- improves comfort on contact with the skin,
- limits fouling,
- increases the durability of surfaces.
When post-processing of silicone parts becomes essential
Frequently asked question: Why post-process a silicone part printed in COPSIL 3D ?
Even with silicones suitable for 3D printing, the extrusion process generates:
- deposit streaks,
- a naturally sticky surface.
These characteristics can limit:
- user comfort,
- ease of insertion/removal,
- functional life.
Post-processing is functional before it is aesthetic.
What is SILISKIN?
This is a three-component silicone coating specifically formulated to adhere to silicone surfaces.
How it works:
- applied in a very thin layer,
- thermal cross-linking,
- formation of a flexible, uniform, and durable film.
SILISKIN has many advantages:
- it follows the elasticity of the silicone,
- does not stiffen the part,
- is compatible with silicone 3D printing.

FAQ
Is it compatible with medical applications?
SILISKIN cotaing is designed for applications in contact with the skin in accordance with ISO 10990-5.
Does SILISKIN alter the flexibility of the part?
No. The film is flexible and follows the elasticity of the silicone.
Is it an aesthetic finish?
Coating is primarily a functional treatment geared toward use. However, it also provides a matte finish.
Can only certain areas be treated?
Yes, depending on the application method chosen.
