Physical data

ZINCA can be applied using most conventional application methods such as brush , roller , airspray – gun and airless spray.

Other application methods using aerosols or by dipping are possible.

 

Surface condition

The best cathodic protection with ZINCA will be obtained when blasting to a standard Sa 2.5 with a roughness Rz of approx. 50 µm. (ISO 8501-1 : 1998).

In some cases a hand cleaning to a standard St 2 can be sufficient.

All surfaces must be prepared to the ISO 8501 -1standard .

Application temperature must be above 5 º C and the difference between surface temperature and dew point greater than 3 º C .
