Colorless FoodGrade varnish suitable for direct and indirect food contact, wood, food displays, utensils, 3D printing parts and others surfaces of the food industry.

Description of the problem

There are many surfaces in the food industry that must be painted to be suitable for direct or indirect contact with food. The surfaces can be very varied such as barrels, casks and cooperage for wine and beverages in general, displays, shelves, trays, wooden elements and other materials for serving food, parts from 3D printers, utensils, open surfaces of ceilings and walls, etc. Fakolith offers various varnish solutions certified for compliance with the European Regulation EU 10/2011 and its subsequent amendments, and also for the American Regulation FDA 21 CFR 175.300. All Fakolith FoodGrade coatings are treated with food contact antimicrobial technology BioFilmStop Green, which helps to inhibit the nesting of bacteria, biofilm and viruses that cause foodborne toxiinfections, thus increasing food and health safety.

Summary of the most common basic solution and procedure

Due to the diversity of existing surfaces, there is no single food contact varnish that can cover all applications, so we recommend that you check the following options to find the one that best suits your case. Starting from clean and dust-free bases, and especially on wood, where the usual sanding and dust extraction processes must also be followed, the following options are currently available:

· Option A - VARNIPACK FOODGRADE: It is an innovative water-based varnish and overprint varnish, fast drying and thin layer, suitable for direct and indirect contact with food, which is presented as the most avant-garde option, both for the packaging industry of MDF, cardboard and similar, as in other multiple wood surfaces or derivatives. For surfaces that require good hardness, medium physical-chemical stress, with easy renovation and maintenance. It has double certification EU 10/2011 and FDA 21 CFR 175.300, which broadens its field of use.

· Option B - FAKOLITH FK-100 FOODGRADE Varnish: When maximum physicochemical performance is required, and the highest direct food contact compatibility in accordance with EU 10/2011 FDA 21 and/or CFR 175.300, the amber varnish version of FK-100 FoodGrade (BPA Compliant) food epoxy may be the most suitable choice.
