KTX 30 is an isomorphic, single-component, transparent anti-graffiti coating which creates a permanent and invisible protection against graffiti paints. The resulting film is fully transparent and does not cause any loss or optical distortion of the surfaces coated. The preparation is quick drying and shows a very high adhesion and durability. The surface protects against aerosol-based graffiti paints, most commercially available markers, dirt, acid rain and alkalines.
When applied, KTX 30 forms a highly transparent separation layer which prevents penetration into the substrate and reduces the pigment adhesion, often causing the so-called “pearling” of fluids. The surfaces protected with KTX 30, thanks to its anti-static properties, remain clean for a long time, which considerably reduces the costs of cleaning and treatment, thus extending the surface maintenance intervals.
The protected glass linings, which are in contact with weather conditions, facilitate the downflow of water and snow, thus increasing the visibility in adverse conditions.
KTX 30 has preserving properties and UV filters, which preserve the colours of the protected substrates, and in the case of damaged, fogged or oxidised surfaces the coating restores their natural appearance. The preparation is offered in two versions: matt or gloss.
KTX 30 has the Technical Approval No. AT/2014-02-3069 of the Road and Bridge Research Institute.
Technical data after application:
Coating durability: minimum 5 years.
Graffiti removal: repetitive.
Dry film thickness: approx. 4 to 8 µm.
Full anti-graffiti protection: after 24 h.
Fields of application:
KTX 30 is used on smooth non-absorptive surfaces such as coatings based on varnish, powder, polyurethane or epoxide, industrial paints, plastics, polycarbonates, glass, zinc, aluminium, as well as natural stones such as polished granite. May be used on inside and outside surfaces of trams, buses, trains as well as on ticket machines and parking meters. Due to its unique transparency, the coating is especially suitable to protect sound barriers made of polycarbonates, polymethyl methacrylate or similar materials.
The preparation is ready for use upon opening the container. Do not mix or shake before use, as it may cause an explosive pressure.
After pouring an appropriate amount of material, close the container to prevent the access of moisture and avoid solvent evaporation. Dose small amounts for application. Do not return any unused preparation to the original container.
Apply a single thin layer of preparation.
Application of anti-graffiti coating: +5 to +28°C. Optimum application temperature: +10 to +20°C.
Due to the evaporation rate, the average time of using the coating after application should be max. 5 min at 20°C, so any corrections should be made immediately.
The anti-graffiti coating becomes touch dry after approx. 1 hour at 20°C; during that time, make sure that no contaminants or water gets in contact with the coating. After approx. 8 to 12 hours, depending on the drying temperature (5 to 20°C), the anti-graffiti coating becomes hard. Full mechanical and chemical resistance is obtained after 7 days at 20°C; during that period, the coating should not be rubbed or scrubbed. The coating obtains the initial protective properties after approx. 24 hours. Maintain an appropriate range of temperature for the entire curing period, avoid direct sunlight and moisture. Moisture causes accelerated cross-linking of the coating and affects its quality and tightness. Once the coating becomes hard, do not cover it with another coating layer or any other preparation or paint. It is important that you thoroughly cover the entire surface with a liquid layer. Failure to do that may cause problems with graffiti removal. Do not apply too much coating, the average consumption is 15 ml/m² and should not be exceeded.
The coating is suitable for outdoor use and for indoors with appropriate ventilation systems.
Pay a particular attention to cigarettes, sparking, and keep away from any possible sources of fire. Wind can convey fumes at long distances.
Methods of application: Spraying: the preparation is applied using HVLP spraying with a 0.7-1.3 mm nozzle, at a pressure of 2 to 3 bar; Manual application: using microfibre, rollers made of microfibre, window washing pads or absorptive lint-free fabrics. Microfibres should be attached to window washing scraper. Apply the coating directly on the microfibre, not on the substrate to be protected. When the microfibre becomes dirty, replace it.
Use as a concentrate. Do not mix with any other liquids.
As a rule, 1 full layer should be applied.
The film thickness (approx. 4 µm) ensures an effective protection.
The preparation is very economical in use. Theoretical efficiency: 66 m²/1 L (15 ml/m²) to 100 m²/1 L (10 ml/m²)
The theoretical efficiency is given in approximate values which specify the extreme amounts used, which differ depending on the type of substrate to be protected. Practical efficiency: depended on the conditions during application, method of application and losses of material.
