SYNTECH POLIUREA SPRAY - FC

Polyurea elastomeric system for contact with food and drinking water

Code: SYN.0307

Components: 2

Appearance: Liquid

SYNTECH POLIUREA SPRAY - FC is a pure aromatic polyurea specifically designed for contact with food substances and drinking water. 100% solid does not contain VOC and can only be applied by spraying using suitable bimixer machines. It is aromatic and is characterized by a high degree of elongation. It is a coating elastomer obtained from the reaction of an aromatic type isocyanate with an amine. PURE POLYUREA SUITABLE FOR FOOD CONTACT

- Possibility to create high performance, very thin layers, with low specific weight.
- Possibility to perform maintenance and/or repairs easy and efficiently.

Consumption

From 2,00 to 2,50 kg of SYNTYECH POLIUREA SPRAY - FC for each square metre of surface to be covered.

Use fields

SYNTECH POLIUREA SPRAY - FC is particularly used as waterproofing on concrete or as a protective coating for water containment tanks, primary containment, driveways and parking lots, purification plants, EPS coating, coating and protection of sheet metal, roofs, balconies and canopies in wood, tanks and pools, seamlessly without interruptions.

Preparation of supports

The support on which the polyurea system must be laid must be suitable for withstanding the stresses resulting from the intended use, such as static or dynamic loads, impacts, thermo-hygrometric dilations, vibrations, etc. As regards the characteristics of the substrate (maximum humidity, cohesion, strength class, flatness, etc.) and the preparation of the surface that will accommodate the resin system, we recommend the requirements set out in chapter 5 of the UNI 10966 standard ("RESIN SYSTEMS FOR SURFACES HORIZONTAL AND VERTICAL - INSTRUCTIONS FOR DESIGN AND APPLICATION "). In any case, carefully clean and degrease the surfaces, removing any kind of dirt, paint residues or incoherent parts. The humidity of the support must be <= 3%. Evaluate the most convenient type of mechanical preparation (shot peening, sandblasting, hydro-washing, etc.). The surfaces must also be free from discontinuity, and possibly leveled and regularized with products from the FLOOR line or the REPAR line. In case of presence (even suspected) of humidity deriving from capillary rising from the substrate, it is recommended to apply in advance the epoxy resin for "wet substrates" SYNTECH PAVIDAMP. Tiled floors, or floors covered with pre-existing resin, must be subjected to mechanical roughening carried out with shot blasting, milling, bush hammering, etc., until the total elimination of the waterproof crust and the opacification of the surfaces. Remove dust after abrasion.
It is recommended to use Primer from the SYNTECH POLIUREA PRIMER range. On particularly absorbent substrates, to avoid the formation of craters / blowholes on the surface of the freshly sprayed product, it is recommended to use primers from the SYNTECH POLIUREA PRIMER range, always contacting the Azichem technical staff for clarification on the most suitable type to use. Apply several layers of primer until the porosity is saturated and providing a light dusting with clean and dry quartz sand (0.4-0.7 mm). Never dust off the primer. Provide suitable elastic sealing systems to cover joints, fittings, cracks or fissures subject to significant movements.

Use method

Pure polyurea SYNTECH POLIUREA SPRAY - FC requires a bimixer system capable of producing pressure above 180 bar and temperatures above 65°C. Contact Azichem technical staff for clarification on the best gun to use and details of the system air.
