WRAS drinking-water reservoirs

Notas de ingeniería. No un blog. The WRAS drinking water membrana in Catalogue 2024 is Polyurea Rayston (pure poliurea). The sheet prints WRAS according to BS6920. It also prints CE EN-1504-2, ETA ETAG005 16/0148 and BBA 18/5582. Therefore a roof 1K coat is not a reservoir lining.
Where the WRAS drinking water membrana is written
Polyurea Rayston is listed for drinking water tanks as well as wastewater treatment plants. It is a proyectado en caliente 100% pure poliurea. A protective acabado is required if the coating is exposed to UV. Impermax Aqua 2K is a different water-retaining poliuretano. It is not the WRAS name.
However, do not move WRAS onto Impermax (monocomponente moisture-cured poliuretano, 1K PU). Do not move it onto Impermax Polyurea H. Also, do not invent a litre or kilogram rate.
Reservoirs, drinking-water tanks and related hydraulic work sit on the applications page. Imprimación choice stays on the current TDS for the soporte that is there. Then use the calculadora for area.
How to cite the lining
First, write Polyurea Rayston (pure poliurea). Then write WRAS. After that, send the reader to documents. See drinking-water reservoirs, Polyurea Rayston, documents and the calculadora.
Outbound reference: WRAS Approvals.
A roof coat is not potable. Write Polyurea Rayston and WRAS only where Catalogue 2024 prints them.
Therefore the current TDS remains the source for mix ratio, overcoat and consumo. Then the calculadora sizes the area. However, a number invented here would be a specification error. In addition, the application page is the schedule. First name the exposición. Next name the commercial product and the chemical type in the same sentence. After that, open documents. Also keep the finish on the same clause as the body. A sample, a colour or a photograph does not replace that sentence.
These notes do not replace the current TDS, SDS or a written specification. For pack sizes, mix ratio and kg/m², read the ficha vigente, then the calculadora.
