KIMITECH K40 NF RESINS
Two-component colored epoxy resin, solvent-free, for protective painting of reinforced concrete works
Kimitech K40 NF is a two-component, solvent-free, highly adhesive water-based epoxy resin, resistant to hydraulic thrust, with excellent resistance to chemical agents, available in both colored and neutral colors that can be colored with compatible universal pastes.
For concrete structures, it constitutes a protective system, able to improve the impermeability of reinforced concrete products, increasing their durability (also against aggressions due to sulphates and chlorides)

USES
- Protective painting of concrete works subject to chemical or physical aggression (channels, pipes and collectors for sewers, tunnels, purification plants).
- Resin floors and coatings (Kimitech K40 NF must always be protected with suitable transparent polyurethane finishes to obtain more easily washable surfaces, with greater resistance to color changes, scratches and wear).
- Continuous wall coverings, especially in the case of industrial activities, including food (being odor-less), without interrupting production cycles.
- Colored tricomponent painting self-leveling epoxyresin (Kimitech ECA) or trowable (Kimitech ECF) resin systems. In this case the interventions must be completed with the final application in a double coat of Kimifloor ECO-FINITURA single-component polyurethane resin
- Painting of floors with a vapor barrier (after priming with Kimicover FIX and providing a final transpa-rent polyurethane protection)
- Kimitech K40 NF can be used for floors and coatings in compliance with the HACCP system and with the require-ments of EC Regulation no. 852/2004 related to the hygie-ne of food products.
APPLICATION AREAS
Kimitech K40 NF is supplied in two pre-dosed containers (A + B), of which the "B" part is oversized to allow an easy mixing. To prepare the material, pour component "A" into component "B", mix thoroughly with a low-speed drill (200- 300 per minute) until you get a perfect mixture; the mixture must be diluted with about 15-20% of clean water. Mix a quantity of product not exceeding that which can be applied within the frost time.
In case of fractionated mixing, respect the ratios by weight (not by volume) indicated in the packages. In case of protective painting of concrete works, sand the surface in order to make it compact and free from oils, greases, old paints, release agents and any other material that could affect the good anchoring of the further resin coating; apply a coat of primer Kimicover FIX; Kimitech K40 NF must be applied in min. two coats by brush, roller or sprayed with an airless pump . In case of continuous non-toxic coatings of walls in industries, the substrate must be compact, free from oils, greases, old varnishes and any other material that may affect the good anchoring of the resin coating.
Any leveling must be carried out with Betonfix RS or Betonfix R30, rounding the corners between wall-floor and wall-wall. If you intend to make a colored paint, it is feasible to get a non-slip surface by freshly dusting the surface of the first coat of the transparent polyurethane finish, applied with Kimifill 01-03 and vacuuming the encapsulated quartz the next day before finishing the work with the last coat of protective polyurethane. In case of applications in more than one coat, if there is a time exceeding 24 hours between one coat and the next, it is necessary to sand and carefully aspirate the substrate before reapplying the product.
