Belzona’s Interactive Solutions Map navigates you through a sample waste water treatment plant showing the areas and equipment that are typical for most types of water treatment plants.
The Map provides description of each area and equipment at the plant, highlights typical problems and offers potential solutions by Belzona. With this map you will be able to learn what problems waste water treatment plants may experience and how to mitigate and solve them utilizing polymeric technology.
Wastewater Solutions MapNanoPrep
Rust Primer & Anticorrosive Industrial Coating
NanoPrep’s surface preparation technology allows industrial coating application in areas where it is difficult, cost prohibitive or impossible to perform surface preparation by abrasive grit blasting.
NanoPrep is a one component, waterborne, acrylic co-polymer composition that reacts and cross-links with rusted steel surfaces, clean steel, painted steel, aluminium, and/or galvanised steel surfaces creating superior anticorrosive properties.
Outcomes and Benefits
- No blasting
- No heavy protective gear
- Chemically reacts for perfect adhesion & top performance
- Quick drying saves time
- No VOC’s
- Safe and simple to use
- Non flammable
- Long shelf life
- Primer for many top coats
