Application Guide Direction
Surface preparation :
Surface preparation should include sand blast, grate blast, shot blast… cleaning up to Sa2.5 grade and to a minimum of 50-70 microns anchor profile. Then remove dusts by blowing compressed dry and clean air. During blasting operation and coating application, the substrate temperature should be 3˚C more than dew point.
High relative humidity may affect adhesion negatively. So maximum allowed relative humidity would be 85%. In some cases pre heating of pipes may be needed. The substrate must be coated max in 4 hours after sand blasting, if not, the surface preparation process must be done again.
POLYPIPE HOMA-11 must not be diluted at all. Use polyurethane thinner T-900 for purge line and flushing of equipment.
Part A is thoroughly mixed with suitable mixer until a homogeneous mixture and color is obtained.
This material must be applied utilizing high-pressure, heated plural component spray proportioning equipment. Leave the cut backs (about 75 mm) uncoated. In other cases, such as couplings all the surface will be coated.
- Limitation :
Do not open the packages till application time. Should be stored in a sealed container after opening. Minimum immersing or burying time is 4-6 hours after application.
- Storage :
12 months in factory delivered, unopened drums. Keep away from extreme heat, freezing, and moisture. The use of drum heaters is encouraged to reduce material viscosity at low temperatures.
