Product description

DESCRIPTION: FK-450 FoodGrade is a high-performance, two-component, water dilutable modified epoxy FoodGrade paint with high solid content, low voc, low odour and EC marking. FK-450 FoodGrade is the first FoodGrade epoxy water soluble paint that ensures limitation of migrations, generates a high-gloss impermeable film that is easy to clean and disinfect with water at temperatures of up to 90ºC. Its excellent covering and vapour barrier effect qualities ensure its function as an excellent waterproofing agent and long term anticorrosion treatment when is applied on metals in combination with a correct anticorrosion primer system. Compatible with most of primed surfaces, the duly primed metallic surfaces, lacquer-finish sandwich panels and compatible previous paints and/or primers with good adherence and resistant to cross-cut test Class 0-1 UNE-DIN EN ISO 2409:2007. FK-450 FoodGrade is highly resistant to abrasion UNE EN ISO 5470-1:1999 and highly resistant to aggressive chemical attacks UNE EN 1504-2:2005 (chemicals compatible for epoxy), with UNE Shore hardness of 80±5 units, Shore D EN ISO 868:2003 (23±2ºC; 50±5%Hr), covering Class 1 (300 µm dry film) and damp rubbing Class 1, DIN EN 13300. Paint resistant to the most disinfectant cleaners according to Tests DIN EN ISO 4628-2: 2004-01 by TÜV SÜD Germany and/or Fakolith R&D+i (For more security, before use, ask your case to our Tech. Department).

FOODGRADE PAINT CERTIFIED AS APT FOR DIRECT CONTACT: FK-450 FoodGrade epoxy paint duly complies with all current European regulations regarding materials that come into contact with foods, (EC) Regulation 852/2004, (EC) Regulation 1935/2004, (EC) HACCP Regulation 1895/2005, and (EC) GMP Regulation 2023/2006, as well as Spanish RD 847/2011 and (EU) Commission Regulation No.10/2011, and lasts amendments EU 2018/213 (BPA Compliant), regarding plastic objects and materials designed to come into contact with foods. To this end FK-450 FoodGrade has been tested with simulants A, B, C (OM2-40ºC) and D2 (OM2, 20ºC), as shown in the trials run by Fakolith, through independent certificating entities such as Tecnalia and the CNTA (Spanish National Food Technology Centre), among others, insofar as there is compliance in all of the tested cases with the overall and specific migration limits imposed by the Regulation for the above-mentioned simulants, which are equivalent to all of the simulants and, as a result are apt for direct contact with all foods and drinks (with the exception of vinegar, which damages epoxy resin. Not suitable for foods intended for infants or young children according definitions at regulation (EU) No. 609/2013.). FK-450 FoodGrade will have Declaration of Compliance – Health Register FAKOLITH RGSEAA ES-39.005259/T. Available in transparent and the most standard industrial colours for the food industry and the health sector.

AQUA-FOODGRADE TECHNOLOGY: FAKOLITH FK-450 FoodGrade is the first high-solids 2-component epoxy food paint that does not contain or require solvents or additional alcohols for its application. Mix A + B incorporates water in emulsion as solvent. This is a milestone that will facilitate drying at a suitable or forced temperature, since water is much easier and safer to evaporate. Especially in confined spaces, as there are no flammable or volatile materials during application and curing, it represents a great novelty and advantage.

RECOMMENDED USE: FK-450 FoodGrade epoxy paint is specifically formulated for the protection and finishing of surfaces that come into direct contact with all manner of foods and drinks, in line with current European regulations, and is for application to the interiors of food tanks and silos, pipes, food transport elements, skirting boards, floors, walls, ceilings, objects, machinery, installations, structures, etc. located in interiors. Generally, for use in the food industry, the health sector, the pharmaceuticals and cosmetics industry, construction and civil engineering.

HOW TO APPLY: Following adequate preparation of the surface and having confirmed the suitability of the environment, FK-450 FoodGrade paint can be applied by brush or roller, or for finishes and optimum applications using AirMix or Airless with heated hose type spraying equipment. Slowly pour component A into component B (never the other way round), mix together gently using an electric mixer, for at least 2 minutes or until the components have blended completely together, and then leave to rest for 1 minute before starting to apply. When mixing always use complete batches of component A and component B, to avoid errors in the mixing ratio. Plan carefully its application, bearing in mind its short pot-life of the mix. It can be applied over fibreglass netting systems, in tanks and on floors, mixed with non-slip quartz sand. Should it be necessary adjust the viscosity of the paint by thinning with 5-10% potable water.

ATTENTION TO THE CONDITIONS OF APPLICATION AND CURING: Drying time and the waiting time for the second coat depend on layer thickness, temperature, relative humidity and ventilation. The environment and base temperature should never be lower than + 10ºC and higher than 35ºC, and the relative humidity should not be higher than 70-75%. The surface temperature of the base to be painted should always be at least 3 ° C above the dew point to avoid condensation. It is estimated that the ideal application temperature is around 20ºC and 60% relative humidity. In the event that environmental conditions are not appropriate for its application and curing, these should be adapted with extraction and ventilation of air, either at room temperature, with cold or heat, with dehumidifiers, etc., until the environmental conditions are adequate and stable during the application and curing, and always avoiding the generation of moisture condensation, since this would prevent the proper curing of the paint, especially made to monitor in tanks and confined spaces. Epoxy paint should not be in contact with water or surface condensation during the first 72 hours of curing, or the paint may not cure properly, appearing "Amine Blush" wash spots.

DEPOSITS OF FOOD LIQUIDS: In general, the film will present its complete curing, from 10 to 21 days for contact with food and drinks (cured at 23ºC, 50% relative humidity, layer> 300 microns dry). At a lower temperature and / or higher humidity and layer, the curing time can be significantly increased. On the other hand, if the temperature conditions are higher, the humidity is lower and / or there is less coating, the curing time can be significantly reduced. It is necessary to maintain suitable environmental conditions during application and curing, for which it is necessary to use ventilation systems with air extraction and forced hot air, preferably dehydrated, avoiding condensation, to maximize the curing conditions. Before filling a tank that has been coated with FK-45 FoodGrade paints range, the complete curing of the film should be checked, as well as at least an initial cleaning on the entire surface, with clear water, or preferably with neutral soap and later rinse.

FORCED DRYING: In general, applications with forced drying with hot air dehydrated can greatly reduce the drying, curing and commissioning time. An example of this can be the application in interior of pipes, where specialist companies after the application with systems and special equipment, artificially circulate a current of hot dehydrated air, and after checking the correct curing, make a later washing with water, before of the definitive commissioning. The contribution of heat at a higher temperature shortens the programming of the curing cycle. For more details, consult technical data sheet and / or application guides, and safety data sheet.

OTHER GENERAL APPLICATIONS: This paint offers good general resistance, at least after 72 hours of curing, although we recommend not exposing the paint film to severe chemical-physical aggressions until it has been cured for at least 1 week (walls, floors, ceilings, indirect contact).
