TINUVIN CarboProtect
Applications
TINUVIN® Carboprotect® was developed to stabilize carbon-fiber-reinforced plastics, making it possible to visibly display the embedded carbon fibers. Carbon-fiber-reinforced plastics are used as building elements, for example, in aerospace or automotive applications. TINUVIN® Carboprotect® blocks the destructive radiation from UV and near-UV visible light and keeps the matrix intact. This allows customers, besides benefiting from the excellent mechanical properties, to also utilize the high aesthetical value of carbon-fiber-reinforced plastics for design purposes.
TINUVIN® CarboProtect® is recommended in applications such as:
- Coatings over carbon fiber-reinforced plastics (CFRP) or glass fiber-reinforced plastics (GFRP) embedded in an epoxy matrix
- General coatings or substrates needing protection up to 420 nm
- General coatings over substrates very sensitive to UV-A energy
For outdoor applications, TINUVIN® CarboProtect® needs to be combined with a hindered amine light stabilizer (HALS) such as TINUVIN® 123 (for acid catalyzed systems) or TINUVIN® 292 (for 2K PUR).
TINUVIN® CarboProtect® is recommended in binder systems such as:
- 1K and 2K PUR (acrylic/NCO, PES/NCO, …)
- Thermosetting (acrylic/melamine, PES/melamine, …)
- Thermoplastic (acrylic, vinylic, …)
