Phila-Atoxatria for Drinking Water Tanks 

Overview

High thickness coating, approved for drinking water and food solutions. Atoxatria is a double-component, non toxic, epoxy-polyamide resins based coating, without solvents, with stable pigments and waterproof braking effect, providing the product with high chemical resistance to eatable oil, drinking water, and various liquids (oil, vegetables, beer, etc…) or solid foodstuffs (wheat, Indian corn, fodder, etc.). Excellent mechanical resistance, glossy aspect, the product does not adulterate foodstuffs’ taste or odor. It is suitable for sterile and hospital environments. 

Purpose

Suitable for reservoirs or tanks composed of: iron, concrete, galvanized sheet, or prefabricated cement.

Coating Specification

It is recommended for: Constant immersion in drinking water, wine, beer, vegetable oils, solid substances, cereals, corn, starchy food, fodder. It is not recommended for: Immersion in alcohol, concentrated acids and alkali, ammonia, solvents. 

Recommended primers and finishes: Plastofond As, Mioxide, Miox, Idrosem wp. 

Safety precautions: The product is inflammable. Respect the safety norms in force for transport, storage and application. In case of application in closed places, provide a proper ventilation or forced exhaust. . Do not waste the empty tins in the environment, let them dry and dispose them of as special waste. For any further information, see the technical data.  Tender Item: Application of Atoxatria, , non toxic, epoxy-polyamide resins based topcoat, with braking effect pigmentation over internal surfaces of iron reservoirs and concrete tanks, containing liquid or solid foodstuffs, with a consumption of 0,250 l/Sq.m., excluded practical operating loss

Surface Preparation

New iron: sand-blast until the iron is exposed, with degree 2 ½ of Svensk scale - Standard SIS 1967 (SPCC SP 5) and apply, Plastofond AS, Miox primer, or directly Atoxatria over the metal. Painted iron: remove mechanically the old paintwork. Sandpaper to obtain a good adhesive power (Mioxide), putty any imperfections with epoxy putty (Epostucc) and apply two or more coats of Atoxatria, until a minimum thickness of 250 dry micron is reached.  New concrete, masonry and cement mixtures: Check that the surface is dry and has seasoned for at least 28 days. Remove any peeling or chalking parts, by staking or sanding the surface. Apply one coat of strengthening, double-component, water based primer (Idrosem wp). Putty any imperfections with Epostucc (cracks and holes), sand, if necessary and apply Atoxatria with a minimum thickness of 210 micron dry film, and a consumption of 0,400 kg/Sq.m.. Coated and partially deteriorated concrete, masonry and cement mixtures: value each time the coating’s adhesive power over the surface. If the chalking parts are below 10%, it’s possible to remake the surface, otherwise it is highly recommended to remove the old coating by sandblasting or staking or by any other proper system. Anyway, a double-component, strengthening, hydro-dilutable primer (Idrosem) is to apply. Even out any imperfections (cracks and holes) with an epoxy putty, sand, apply the insulating primer over puttied and uncoated areas. After drying, apply Atoxatria with a minimum thickness of 210 micron dry film, with a consumption of 0,400 kg/Sq.m. Application notes: Atoxatria, as any other epoxy product, chalks if exposed to UV rays. Do not apply at temperatures below + 10 °C and above + 35 °C, with air relative humidity below 65%,, with higher humidity and lower temperatures. The applied film tends to whiten on the surface, but this phenomenon does not reduce the product’s chemical and mechanical resistance. Atoxatria is not to be applied over surfaces with salt efflorescence or osmotic rising damp, otherwise it won’t adhere to the surface. Before applying Atoxatria, mix properly the base and the hardener. Eventually pour the mixture  in a clean tin and go on blending. This operation is necessary to avoid having non mixed product in the tin.  WARNING: the product without the proper hardener ratio does not harden and does not reach the proper chemical resistance features. Atoxatria is to apply within 1 hour from preparation. 

Storage

Circa 24 months. Protect from frost and direct sunlight. Do not use near fire or flammable materials.

Health and Safety

Prior to use, obtain, consult and follow the Material Safety Data Sheet for this product concerning health and safety information. Read carefully and conform to precautions on MSDS and packing vessels. To avoid eye and skin contact, tools such as gloves, goggles and face mask etc. should be used during work with product (proper safety measures should be taken according to construction methods and circumstances). All work with the product must be carried out according to all relevant national health, safety and environment standards and codes. This product is for professional use only.

Limitation of liability

All information is given for guidance only and is subject to regional variation depending upon local climate and environmental condition. An excessive film thickness delays the final curing and creates sagging. Over coating interval will increase with the number of paint layers and the thickness of the paint film. For recommended paints at special circumstances, please consult with our Philadelphia Coatings LLC. Apply in good weather. The relative humidity must not exceed 80% temperature of the surface to be coated must be at least 3°C above the dew point. All data from the tests is obtained under lab conditions, so Philadelphia Coatings LLC won’t bear any liabilities from the condition whether the data could reflect the objective status of the actual application circumstance or not.
