NOTE: Flammable and exploision products should be kept away during the application. Protective gloves and masks should be used for hands and eyes during application. The product should be used in well ventilated environments.If the material comes into contact with eyes, it should be washed immediately with su¬cient water. Childrens should kept away from the product. For more detailed information, ask for the Safety Data Sheet (MSDS).
Karıştırma
The product is two-component. It is recommended to prepare only the amount that can be consumed within the pot life. Excess material prepared beyond the pot life cannot be used. To obtain a homogeneous mixture, ensure that the product temperature is at least +15°C. Component A should be mixed in its original container using a mechanical mixer at approximately 300 rpm for about 2–3 minutes. Then, the hardener (Component B) should be added to Component A. Components A and B must be mixed until a homogeneous consistency is achieved.
Uygulama
The prepared primer mixture should be applied by brush, roller, or airless spray, ensuring that all surface pores are fully sealed. The prepared mixture must be consumed quickly, taking the pot life into consideration. The waiting times between coats are critical for the durability and performance of the final coating system. Full curing, including mechanical and chemical resistance, is achieved after 7 days. All tools and equipment should be cleaned as soon as possible using BYK TN 100. Rollers are disposable and are not suitable for reuse.
Surface Preparation
For Metal Surfaces: In order to achieve top level performance, sandblasting should be done at Sa 2 ½ level.The sandblasted surface should be primed with a dust rich epoxy primer or phosphate rich epoxy primer to form the required dry film before recording product identification information.
For Concrete Surfaces: The concrete surface must be clean, solid and have sufficient compressive strength (>25N/mm2), and tensile strength must be >1.5N/mm2. The concrete floor to be insulated must be solid and there must be no movement on the surface. The grout layer on the surface must be removed. The concrete to be insulated must be at least C25 and preferably C30 – C35 standard.
Concrete Standards: The surface should be cleaned with pressurized water and freed from oil, grease, dirt, mortar particles and dust. Concrete surfaces should be prepared to obtain an open porous surface by removing cement grout using abrasive equipment.It should also be completely cleaned from mold release agents, cement residues, shavings, loose particles and uncured membranes. The grout layer on the surface must be removed. (Shot-Blast, Rota Tiger etc.) If the surface is too shiny, it should be roughened with milling or sandblasting. Concrete cracks should be cut in a V shape, cleaned and false joints should be cleaned.
| Surface Temperature | Min + 10 °C / Max + 30 °C |
| Ambient Temperature | Min + 10 °C / Max + 30 °C |
| Material Temperature | Must be between + 10 °C and + 30 °C. |
| Surface Moisture Content | The moisture content in the concrete must be max. 4%. |
| Relative Humidity | Must be max. 80% |
| Dew Point | The ground temperature must be at least 3 oC above the dew point during application. |
