ProGuard is a coating that
is a designed solution to a request for a new coating material to be
manufactured to fulfill new standards in safety in road tunnels. The
scope of this request is summarized below:
- Increased tunnel safety by
reducing pollution and easier, faster cleaning. A bright, stable and
clean tunnel was the primary aim.
- Reduction of maintenance
time. Simple, chemical free cleaning procedures. Cleaning with water
(low-medium pressure spray) and rotating brush.
- Increased resistance to
environmental influences (temperature, moisture, chemical attack from
salts, diesel soot, rubber abrasion etc.
- Protect the value of the investment – robust and durable coating (one coat to last 30 years).
- Minimisation of risk in application.
- Not critical to application conditions (temperature, moisture).
- Short tunnel closures.
ProGuard is a new
technology coating material produced for application on highly
stressed concrete surfaces. ProGuard is an organometallic coating,
that is, it has both organic and inorganic components. Compared with
traditional coatings that are inherently organic (polyurethane,
acrylic, styrene acrylic etc) these new hybrid coatings have some
exceptional properties. Some properties include:
