Novacel 9343 protective film: features, applications, and performance
The Novacel 9343 protective film is a reliable reference for protecting sensitive surfaces during transport, storage, or processing.
Its acrylic adhesive guarantees stable adhesion without leaving residue upon removal, ideal for aluminum, lacquered steel, or plastic.
Available at Dagobert Industrie, it meets the requirements of professionals who cannot afford to deliver a scratched or soiled surface.
What is the Novacel 9343 protective film?
The Novacel 9343 is a temporary protective film manufactured by Novacel, the French specialist in adhesive films. It protects sensitive surfaces during manufacturing, transport, and storage phases.
It is primarily aimed at industrial manufacturers working with metallic, plastic, or painted surfaces who require reliable protection without leaving residue upon removal.
Composition and structure of the Novacel 9343 film
The 9343 is based on a two-layer structure: a polyethylene (PE) backing and a water-based adhesive layer. This type of formulation ensures controlled adhesion and clean removal.
The adhesive is non-migrating: it does not transfer residue to the protected surface, even after several weeks of application. This is an essential criterion for high-value-added parts.
The film is distinguished by:
- A flexible PE backing, easy to apply by hand or machine
- Light to medium adhesion, suitable for smooth and semi-smooth surfaces
- Good UV resistance for short-term outdoor use
- High transparency allowing for visual inspection of the surface without removing the film
| Product | Backing | Adhesion level | UV resistance | Typical application |
|---|---|---|---|---|
| Novacel 9343 | Flexible PE | Light to medium | Short term | Metals, plastics, painted surfaces |
| Novacel 4956 | Flexible PE | High | Limited | Aluminum profiles, rough surfaces |
| Novacel 9200 | Flexible PE | Very light | Low | Glazing, very smooth surfaces |
| Tesa 4848 | PVC | Medium | Good | Metallic surfaces, prolonged outdoor use |
Technical properties and performance of the Novacel 9343
The Novacel 9343 is a polyethylene (PE) protective film with an opaque black backing. It is designed to protect sensitive surfaces during manufacturing, transport, and storage phases.
Its adhesive is a low-residue acrylic: it sticks without leaving marks or glue on the protected surface. This is a critical point for applications where surface cleanliness is required after removal.
The film features controlled and time-stable adhesion. Adhesion does not increase even after prolonged exposure to heat or UV, which facilitates removal at the end of the process.
Key technical characteristics:
- Backing: opaque black polyethylene
- Adhesive: solvent-free acrylic
- Total thickness: approx. 70 µm
- Thermal resistance: up to 80 °C for short-term use
- High elongation at break: good conformability on complex shapes
- Guaranteed clean removal on smooth and painted surfaces
The opaque film offers a dual advantage: it mechanically protects the surface against scratches and minor impacts while visually masking the part during intermediate operations.
At Dagobert Industrie, we offer this film for applications on aluminum, lacquered steel, rigid plastics, and painted surfaces. It is particularly suited for the aluminum joinery, bodywork, and household appliance industries.
Applications and surfaces compatible with the Novacel 9343 film
The Novacel 9343 is a temporary protective film designed to protect smooth and semi-smooth surfaces during manufacturing, transport, and storage phases.
Its repositionable acrylic adhesive allows it to stick without leaving residue. It peels off cleanly, even after several weeks of application.
At Dagobert Industrie, we particularly recommend it for industries that work with high-end or finished materials.
Compatible surfaces:
- Anodized or lacquered aluminum
- Polished or brushed stainless steel
- Aluminum composite panels and profiles
- Rigid plastics: PVC, polycarbonate, PMMA (plexiglass)
- Flat glass and treated glazing
- Painted or varnished surfaces
Typical application sectors:
- Aluminum joinery and facades
- Construction industry: protection of glazing and cladding
- Furniture and signage manufacturing
- Automotive industry: protection of finished parts before assembly
- Electronics and equipment: protection of housings and front panels
The 9343 is not suitable for porous, rough, or non-degreased surfaces. A clean and dry surface ensures optimal adhesion and residue-free removal.
