Adhesive / Pressure-sensitive adhesive
The layer that bonds the film to a suitable substrate. Pressure-sensitive adhesive develops contact with the surface during fitting; it is distinct from the carrier and top coat.
PPF / Technical reference
The language of paint protection.

Materials & construction
Cap sheet
A removable protective sheet supplied on the top side of certain film products. It protects the finish during handling; the exact removal sequence is product-specific.
Film thickness
The measured thickness of a specified layer or layer combination. Values are only comparable when the included components and measurement basis are clear.
PPF / Paint Protection Film
An adhesive film designed to protect compatible painted surfaces. Automotive PPF can be clear, matte or coloured; the intended protective use distinguishes it from a purely decorative wrap.
PVC / Polyvinyl chloride
A polymer used in many film products, including conventional vehicle graphics. Its performance varies with formulation and construction. PVC and TPU are different material families.
Release liner
A temporary backing that protects the adhesive before installation. It is peeled away during fitting and does not remain as a protective layer on the vehicle.
Top coat
The exposed surface coating of a film. It influences appearance and interactions with dirt, cleaning and fine surface marks; its chemistry and behaviour vary by product.
TPU / Thermoplastic polyurethane
A family of thermoplastic polyurethane materials. Grades can be flexible and elastic; properties depend on formulation. TPU is commonly used as a carrier material in automotive PPF.
PPF / Reference
Surface & optics
Gloss
The visual impression of concentrated reflection from a surface. Glossy PPF is intended to retain or produce a reflective appearance over the underlying colour.
Hydrophobic surface
A surface that resists wetting by water, often visible as water beads. This describes an interaction at the surface rather than the film’s ability to resist an impact.
Matte finish
A low-gloss surface appearance. Matte PPF may suit a compatible matte-painted vehicle or change the sheen of glossy paint.
Optical clarity
How clearly the underlying colour and detail are seen through a transparent film. Haze, texture and colour influence can affect the result.
Orange peel
A description of fine visible surface texture, especially noticeable in reflected lines. The apparent texture can come from the paint, film construction or installed surface.
Satin finish
A finish described as between very matte and high gloss. Product names are not standardised measurements, so two "satin" films may look different.
Self-healing
The ability of certain film surfaces to recover from fine marks under specified conditions. The response belongs to the particular coating system and may be assisted by warmth.
PPF / Reference
Installation
Bulk installation
Fitting film from roll material with trimming as part of the process rather than using only a finished pre-cut outline. Methods differ by installer and panel.
Edge lifting
Loss of adhesion at a film edge. Paint preparation, contamination, tension, edge geometry and subsequent exposure can all need assessment.
Installation gel
A gel-form installation aid used in some approved film-fitting systems. It is an alternative process aid, not a universal ingredient required for all PPF.
Paint correction
A preparation process intended to reduce suitable surface defects in paint, often involving polishing. It is separate from applying a protective film.
Plotter cutting
Cutting film on a plotter from a digital pattern before it is installed. Pattern design and adjustment determine the covered outline.
Pre-cut kits
Sets of film pieces cut for particular areas or a vehicle model. The kit describes the supplied shapes, not a guarantee of easy installation.
Slip solution
An installation liquid used with suitable wet-applied films to assist positioning. Its ingredients, concentration and handling must match the film supplier’s instructions.
Stretching
Deforming the film during fitting so it follows a contour. The permissible amount and method depend on the product and shape.
Tack
A term for the immediate adhesive grab encountered during positioning. It is not identical to the final bond strength after the specified installation and settling process.
Wrapped edges
Film returned around a suitable panel edge so its boundary is less exposed on the visible face. Geometry and available access determine feasibility.
PPF / Reference
Coverage
Full body
Broad coverage across the vehicle’s painted exterior. It is still a scope description that needs a panel list and exclusions.
Full front
A package label commonly used for coverage of major front-facing panels. The exact list is not standardised and must be specified in the quote.
Partial front
A coverage approach that protects selected leading portions of front panels. The area and package composition vary.
PPF / Reference
Care & ageing
Contamination
Unwanted material on or under the film. Surface deposits such as insects differ from particles trapped during fitting.
Film removal
The controlled process of releasing the adhesive film from the substrate and dealing with residues. Suitability and technique depend on film and paint condition.
UV stability
The ability of a material or system to resist changes under ultraviolet exposure. It is not the same as a measurement of how much UV reaches the substrate.
Warranty versus service life
A warranty states contractual coverage and conditions. Service life describes how long the installed film remains suitable in its actual environment.
Yellowing
A shift toward a yellow tint in the film or its appearance. It should be distinguished from removable deposits or staining on the surface.
PPF / Reference
Protection methods
Ceramic coating
A surface treatment used to influence appearance and cleaning behaviour. It does not create the same replaceable physical film barrier as PPF.
Stone chips
Localised damage caused by debris striking a surface. PPF adds a physical barrier, but the outcome depends on the impact and the film system.
Vinyl wrap
A vehicle film primarily selected for decoration or colour change, commonly using a different construction from dedicated PPF. Some PPF products also offer colour changes.
