The most universal anti-graffiti coating.
Through scientific research supported by numerous tests, we have developed a high-tech anti-graffiti paint marked KTX 07.
Principal characteristics and qualities of KTX 07 coating:
- a durable synthetic system allows repetitive removal of graffiti (up to 100 cycles);
- single-component preparation – does not require component mixing, does not generate losses caused by the curing of coating that was not used in a specific time – easy application;
- creates a transparent coating which facilitates graffiti removal;
- quick-drying, hardened by the air humidity;
- vapour permeable;
- removal of graffiti using only normal water or antigraffiti removers;
- anti-adhesive, creates an anti-poster effect – poster tapes and adhesives are more difficult to stick to the protected surface;
- UV-resistant, does not turn yellow;
- 20-year durability;
- high chemical resistance;
- very good application parameters: from -5 to +30°C;
- finishing variants: matt, gloss, RAL colour;
- environmentally friendly – does not require any aggressive preparations based on solvents or anti-graffiti acids;
- safe when removing graffiti paints – does not require any solvents harmful to the respiratory system, skin or eyes;
- applied using a roller, paintbrush, air spray or airless spray;
- may be applied on different substrates;
- Technical Approval No. AT/2016-02-3286 by the Road and Bridge Research Institute;
- certified – construction mark B.
The KTX 07 anti-graffiti coating has the Technical Approval by the Road and Bridge Research Institute – it is an official state document authorising to use KTX 07 e.g. on engineering structures and in metro tubes.
Description of the preparation
KTX 07 is a unique, single-component anti-graffiti coating which dries up creating a transparent surface and is based on synthetic organosilicone compounds, used to protect surfaces against graffiti and posters, with high anti-adhesive properties, which makes the application of posters, stickers and self-adhesive tapes difficult or even impossible. The anti-graffiti preparation is quick-drying, hardened by the air humidity, and shows a very high level of adhesion. The coating protects very well against aerosol-based graffiti paints, most commercially available markers, ink, bird droppings, dirt, acid rain, moisture, chewing gum, as well as posters, stickers and glue. Once applied, KTX 07 forms a separation layer which prevents penetration into the substrate and reduces the adhesion of paints/pigments/glues, causing them to accumulate on the surface in groups that are easy to remove. KTX 07 is diffusion open, has preserving properties and UV filters, which help to preserve the colours of the protected surfaces. It prevents the penetration of water and harmful substances. The surface texture is maintained. The preparation is available in three variants: gloss, mat/semi-matt and RAL colour.
KTX 07 has the Technical Approval No. AT/2016-02-3286 of the Road and Bridge Research Institute.
Technical data after application
Coating durability: up to 20 years. Graffiti removal: up to 100 cycles (first degree of removability). Dry film thickness: up to 180 µm. Full anti-graffiti protection: after 7 h. Hydrophobic product. No significant reduction of steam diffusion. Full hardness: after four days. The coating has a function of an elastomer exhibiting a high level of deformability with resistance to time and adverse environmental conditions, e.g. UV radiation, alkalines, salt compounds, corrosion, thermal, biological and chemical factors. KTX 07 is a durable system which allows repetitive removal of graffiti paints.
Appearance on the substrate
On the substrate, the anti-graffiti coating creates the effect of matt/semi-matt or gloss (depending on the version), which may be more or less visible based on the type of substrate, sunlight and light incidence angle. Certain absorptive substrates (such as concrete) may become darker – in this case we recommend the PX 07 primer, which prevents/minimises the surface darkening effect.
Fields of application
KTX 07 can be applied on absorptive surfaces, both smooth and porous, made of construction materials such as cement-lime blocks, fibre-concrete panels, brick, clinker brick, plaster, concrete, natural stone (e.g. sandstone), granite, travertine, most paints, as well as on sculptures, monuments, wood and in insulation systems. It is also suitable for non-absorptive surfaces such as ceramics, some plastics, laminates or steel. Due to the diversity of the protected substrates, before application we recommend preliminary tests to check the preparation’s reaction with the substrate, determine the adhesion, surface colour deepening, etc.
Compatibility with other painting systems
KTX 07 is compatible with most primers and surface paints, including paints based on polyurethane, epoxides, 2K acrylic systems, 2K polyurethane systems, anti-corrosion and solvent-based coatings, paints and enamels based on solvents, alkyds, oil, chlorinated rubbers, nitrocellulose, as well as paints based on vinyl, acrylate, silicate and silicone dispersion.
After opening the container, thoroughly mix the anti-graffiti preparation at its entire volume for approx. 1 minute using a slow-speed stirrer, and then you can start the application.
The mixing process is particularly important for matt coatings due to the matting agent, which must be carefully mixed at the entire container volume. After pouring an appropriate amount of material, close the container (the coating will harden if the container remains open). Move any unused material to other, smaller and clean containers, which should be entirely filled with the coating; any air penetration will cause a slow hardening and subsequent cross-linking of the coating.
In case of prolonged application, mix the coating every 1 hour. Depending on the weather conditions, the average period of using the coating is approx. 2 hours at 20°C, but in less favourable conditions the period can extend even to 6 hours.
Application of KTX 07 anti-graffiti coating: –5 to +30 °C.
Application of PX 07 primer: +5 to +30 °C.
The range of temperatures must remain constant throughout the coating curing period.
The coating should be applied carefully to cover all irregularities and cavities in the material structure; failure to follow this rule may cause problems in graffiti removal.
Apply one or two layers of the preparation. In case of highly absorptive materials, we recommend using two layers of PX 07 primer. The primer will reduce the coating wear and prevent/minimise darkening of the protected surface. The interval between applying the primer and the first layer of anti-graffiti coating should be approx. 24 hours. After approx. 4 hours, at a curing temperature of 20°C, the surface of the anti-graffiti coating becomes hard and you can apply the next layer. The coating becomes fully dry after 6 to 7 hours at +20°C. There are no time limitations for the application of the second layer or filling up the coating. In case of long intervals between applying the layers, wash the surface with water to remove dust or other contaminants. When applying the coating on fresh painted substrates, wait for a couple of days for the paint to get seasoned. If the coating does not attach well to the substrate, use a primer suitable for the type of substrate. Make sure that you do not apply too much coating on smooth surfaces; in case of sagging, use a roller to distribute the coating on the substrate before it dries up. The preparation may be applied using pneumatic or hydrodynamic spraying, with a 12-17 nozzle, or using rollers for solvent-based paints. It can be used in ventilated rooms.
As a rule, 1 to 2 layers should be applied.
Theoretical efficiency: 3 m²/L (333 ml/m²) to 10 m²/L (100 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.
Smooth low-absorptive and smooth surfaces:
7 m²/L (143 ml/m²) to 8 m²/L (125 ml/m²), in total per two layers, e.g. paints, brick.
Highly absorptive low-porous surfaces:
3 m²/L (333 ml/m²) to 6 m²/L (167 ml/m²), in total per two layers, e.g. sandstone, limestone, concrete. The consumption may be higher on absorptive substrates.
Non-absorptive smooth surfaces:
till 9 m²/L (111 ml/m²); jointly for two layers,
till 10 m²/L (100 ml/m²) one layer, only for anti-poster protection e.g.: steel, ceramics, granite, surfaces coated with powder paint coatings.
Practical efficiency: depending on individual cases and applications, including: conditions during application, method of application, shape and roughness of the surface to be protected, substrate absorption and losses during application.
We recommend using a primer to increase the efficiency on absorptive surfaces:
PX 07: 8.3 m²/L (120 ml/m²), in total per two layers.
