TECNOCOAT P-2049 EX

- HIGHLY EXPANDABLE

PURE POLYUREA MEMBRANE FOR

WATERPROOFING, WITH THERMAL INSULATION

PROPERTIES

Two- component, hot-spray expandable pure polyurea membrane for waterproofing, protection and sealing. It is

made up of two highly reactive liquid components, isocyanates and amines, mixed together using our specific

spray equipment TC2049 or similar, to form a solid pure and aromatic pure polyurea membrane, completely

adhered to the substrate, without joints or overlaps, elongable, watertight and waterproof. This polyurea once

applied, expands between 5 and 7 times its volume.

USES

For application in the following situations:

Asbestos /metal roofs.

Non-walkable sloped/flat roofs

Concrete decks, retaining walls, and foundations.

GENERAL SPECIFICATIONS

Two-component, 100% solids content, aromatic highly expandable pure polyurea that once applied, forms a

continuous, seamless, waterproofing, and solid membrane that offers a waterproofing, and watertight behavior to

be applied in irregular substratas as concrete, metal roofs or asbestos

Once applied offers also a thermal isolation behavior

The application and training is done by our spray equipment TC2049 () or

similar

Thanks to its versatility and its drying time approx. 10 seconds allows the adherence to any surface, making it

the ideal product for application on uneven surfaces and in areas of any shape, whether curved or squared.

Joints and any type of union are saved since the finish is uniform and in one piece, providing a surface with

optimal maintenance and cleaning.

His properties allow it to adhere to any surface such as concrete, ceramic tiles, metals, plywood(OSB),

asphalt/bituminous sheets.

In any case or material, the surface must be consistent, firm, clean, and dry when the products are applied.

Recommended applying directly on the concrete deck.

Free from harmful VOC compounds, therefore, it does not hurt the ozone layer (VOC's zero). It's 100%

recyclable by mechanical means friendly to the environment; no gas collection for recycling and/or destruction is

required; it doesn´t emit substance to the environment once installed..

It should be applied in dry conditions avoiding the presence of humidity or coming from the surface to be coated

or the substrate, whether at the time of application or subsequently (pressure from phreatic water level). In the

event there is humidity in the substrate at the time of application.

It is an aromatic membrane and, even though it is stable against solar radiation it requires solar radiation

protection (UV rays) to do not lose its physical and mechanical properties. Therefore, this system needs a

protective polyurethane colored aliphatic resin, Tecnotop 2C, for use in the absence of other physical protection

elements. You can apply Tecnotop S-3000, Tecnotop 2CP or Tecnotop 1C also.

YIELD

The recommended minimum thickness is 10 mm. (400 mils DFT), total yiedl is 2 kg/sqm, applied in various coats. The

total thickness may vary according to support or climatological conditions.

PACKAGING

Metal drums of 225 kg each component (B side: amines and A side: isocyanates).

SHELF LIFE

12 months at temperatures between 5° C and 35° C (41 ºF to 95 ºF), provided it is stored in a dry place. Once the tin

has been opened, the product must be used. B side must be agitated mechanically before inserting the transfer pumps

and use.

APPLICATION METHOD

The following factors prior to application should be checked:

Previous preparations of the substrate through physical processes (substrate preparation (sanding, polishing,

shot blasting, or milling) for laitance and reliease agents as well as for the opening of the surface pore, achieving

a suitable anchorage profile. (CSP 3 -4-5, according to the ICRI)

Existing holes or areas with a lack of material must be repaired using some or our epoxy resins: Primer EP-

1020/Primer EP-1010

Joint fillings with Mastic PU
