POLYUREA CASE STUDY- WATER
DESALINIZATION PLANT, ISRAEL
Polyurea applications for a variety of requirements are growing each day. One of the key markets for Polyurea is the Potable water industry. Recent fi gures quoted on National Public Radio state there are close to 1 billion people worldwide without access to clean drinking water. Much of the existing infrastructure for potable water is also in need of repair or replacement. These facts combine to provide a major problem that can use Polyurea as part of the solution.
The Desalinization Plant in Israel is one of the first to use the newest designs for conversion of large quantities of seawater. The complex geometry of the structures required a system that could be applied in a uniform thickness. Fast curing Polyurea provided the answer and allowed the thickness to be controlled within specifi cations. Depending on the substrate and exposure anticipated, the material thickness was 40-60 mils. The variety of substrates and shapes provided no diffi culties for uniform product application.
The coating system a so needed the elastomeric properties of Polyurea to address any movement or cracking of the substrates. Unlike other coating choices, polyurea can be formulated to meet these needs. At 40-60 mil thickness, the system has been designed for a 25 year service life and is expected to out-perform other portions of the project that utilize other coatings.
