- exceptional productivity of up to 111 m²/L,
- graffiti removal with chemical paint removers,
- anti-adhesive, easy removal of tape and posters,
- UV-resistant, no yellowing,
- 20-year durability,
- high chemical and mechanical resistance,
- has antistatic properties,
- finish version: glossy,
- renews damaged, dull and oxidised surfaces giving them a natural shine again,
- application with absorbent microfibre cloths or HVLP low pressure spraying,
- for use on all non-absorbent surfaces.
KTX 20 is a unique, single - component polymer product which is colourless after drying and is used for protecting surfaces against graffiti. KTX 20 has anti-poster, anti-adhesive and anti-static properties. The preparation dries fast and features very good adhesiveness and durability. Treated surfaces are ideally protected against aerosol graffiti paints and most commercially available markers, ink, bird droppings, dirt, acid rain, acid and base solutions, alkalis, oil. It hinders permanent sticking of posters, stickers, and adhesive tapes. On its application, KTX 20 constitutes a release liner that prevents substrate penetration and its anti-adhesive properties reduces adhesiveness, often spurring the so-called 'beading' effect in liquid substances/pigments. Surfaces protected with KTX 20, owing to its anti-static properties, remain clean for a long time, which positively limits the costs of cleaning and maintenance, and thus extending service intervals for such surfaces. Protected substrate exposed to atmospheric conditions facilitate rainwater and snow run-off, thus improving visibility in adverse conditions. KTX 20 features preservative properties and UV filters, thanks to which it preserves the colour of protected substrates, and in the case of old, damaged, dull and oxidized surfaces the coating restores their natural look. The preparation is available only in gloss variant.
Technical Data After Application
Appearance on surface: transparent coating with gloss.
Coating durability: at least 20 years. Graffiti removal: multiple cycles. Dry coating thickness: approx. 2 - 6 µm. Full anti-graffiti protection: after 24 hours. Full curing: after 7 days. The preparation also features anti-corrosive, water-repelling, anti-adhesive and anti-poster properties with high durability and resistance to adverse external factors: thermal, biological or chemical, UV radiation, alkali, corrosion, salt and ammonia solutions, and the majority of solvents. KTX 20 is a durable system facilitating multiple removals of graffiti paints, without the need for coating restoration after graffiti removal.
Areas of Application
KTX 20 is suitable for use on hard, non-absorptive surface, e.g.: varnish coatings, powder paint coatings, polyurethane coatings, epoxy coatings, industrial paint coatings; plastics, e.g., polystyrene, ABS, polycarbonates, acrylic glass (plexiglass, polymethyl methacrylate) glass, steel, zinc plated substrates, aluminium, as well as natural stone, such as polished granite. It is applicable on interior and exterior surfaces of trams, buses, train cars, as well as ticket vending machines, parking meters and lighting poles. Due to its unique chemical resistance it is especially recommended for protection elements of urban infrastructure.
After opening the container of preparation is ready for use. Before use, do not stir nor shaken the container due to a possibility of and excessive pressure build-up. After pouring the desired amount of the preparation (through a varnish strainer of approx. 125 μm) close the container to prevent impact of humidity and evaporation of the preparation. Apply small portions of the preparation at a time. Do not pour the unused preparation back to the original packaging.
KTX 20 coating application:
- relative air humidity: up to 70%,
- coating application: +5°C to +30°C,
- optimum application temperature: +15°C to +20°C,
- the temperature of the substrate should be at least 3°C above the dew point temperature at that ambient temperature and humidity.
Amount of coating layers:
- the preparation should be applied in one, thin layer.
After curing the coating, it cannot be permanently covered with a second layer. Technological breaks plan on the edges of the wall. If the layer is applied too thick, dried coating is susceptible to cracking.
Drying time KTX 20 at 22°C:
- after 15 minutes: touch-dry,
- after 12 hours: cured, resistance to weather conditions,
- after 7 days: complete curing (mechanical and chemical).
Initial anti-graffiti protection properties the coating features after 24 hours. During this period, the coating should not be forcibly wiped/scrubbed.
Mean coating correction time after application on a substrate is at temp 22°C:
- approx. 5 minutes.
Due to the quick drying of the preparation, correction should be done immediately. Anti-adhesive properties of the coating do not allow the application of another layer. During the coating curing time avoid any pollution, including water. The proper temperature range must be maintained throughout the coating curing time; avoid direct sunlight and humidity. Humidity accelerates cross-linking of the coating and affects its quality and tightness. The coating should be applied precisely, so that the treated surface is entirely covered with a film of liquid and a homogeneous layer is created. Failure to do apply the preparation precisely may limit the effectiveness of the anti-graffiti protection. Make sure that no excessive coating should be applied. If the anti-graffiti coating is applied on newly paint coated substrates, maintain sufficient break time for curing of the paint coating, following Technical Data Sheet of a paint coating system. The coating may be applied outdoors and indoors with proper ventilation. Pay special attention to potential sources of fire. Wind spreads vapours over significant distances.
Manual: microfibre cloth, varnish rollers, window-glass washing pads or lint-free, absorptive fabrics. Another way is to wrap the rubber part of a squeegee or the fabric part of a washing pad with a microfibre cloth. Select suitable application equipment to the size and shape of the treated surface. Apply the coating directly onto a microfibre cloth, not onto the treated substrate. Replace microfibre when it is dirty.
Spraying: the product is applied by means of a pneumatic low pressure (HVLP) spray gun with a 0.7 to 1.3 mm nozzle, under the pressure of 2 to 3 bar.
Use the preparation as a concentrate. Do not mix it with any other liquids.
The basic principle is to apply 1 layer of full/tight coating.
The coating thickness of approx. 2 μm provides for sufficient protection. A layer with thickness of 6 μm is applied to matte, absorbent and uneven surfaces.
Theoretical spread rate: 66 m²/L (15 ml/m²) up to 111 m²/L (9 ml/m²).
Theoretical spread rate is an approximate value defining the extreme consumption figures, which differ depending on the type of the protected substrate.
Practical spread rate: depends on conditions during application, methods of application and preparation application losses.
