Polyurea Coating For Power Plant ,Refineries
Polyurea Coating For Power Plant ,Refineries
Polyurea Coatings and linings are increasingly being used to protect steel pipes from corrosion. Polyurea has demonstrated its ability to last longer than paint and maintenance services and costs are reduced. Polyurea is a great protective coating system for pipes that are insulated with polyurethane foam. Polyureas are also being used to line the inside of water and sewer pipes for infrastructure rehabilitation work.

When you think about chemical ,coatings,polyurea,spray, what do you think of first? Which aspects of chemical ,coatings,polyurea,spray are important, which are essential, and which ones can you take or leave? You be the judge.
You may not consider everything you just read to be crucial information about chemical ,coatings,polyurea,spray. But don't be surprised if you find yourself recalling and using this very information in the next few days.
Polyurea is a coating, lining and joint sealant technology. It is being used successfully for any different applications today. Polyurea coatings and linings are more commonly applied over concrete and steel for corrosion protection and abrasion resistance. They also have tremendous advantages over conventional materials for joint fill and caulk applications due to their fast set nature, high elongation and durability/abrasion characteristics. Polyurea can be molded and shaped by spraying it into molds. Similarly, polyurea is also used as hard coat protective shell over expanded polystyrene (EPS) for architectural molded fascia applications. The markets and applications are endless and on the rise.
Ultimate Linings UL KG 8012 is a fast setting, rapid curing, 100% solids, flexible, aliphatic, color stable, two component spray polyurea ,that can be applied to suitably prepared interior or exterior concrete and metal surfaces. Its extremely fast gel time makes it suitable for applications down to -20°F. It may be applied in single or multiple applications without appreciable sagging and is relatively insensitive to moisture and temperature allowing application in most temperatures.

SURFACE PREPARATION
In general, coating performance and adhesion are directly proportional to surface preparation. Most failures in the
performance of surface coatings can be attributed to poor surface preparation. Polyurea coatings rely on the structural
strength of the substrate to which they are applied. All surfaces must be free of dust, dirt, oil, grease, rust, corrosion and
other contaminants. When coating substrates previously used, it is important to consider the possibility of substrate
absorption, which may affect the adhesion of the coating system, regardless of the surface preparation. Ultimate Linings
recognizes the potential for unique substrates from one project to another.
Wood:
All wood should be clean, dry and free of any knots, splinters, oil, grease or other contaminants. Splintered or rough areas should be sanded. Knots should be repaired using UL BC 371 with sand. Upon full cure of the repair agent, prime the entire surface intended for coating.
Steel (Atmospheric and Immersion Exposure):
Remove all oil, grease, weld spatters and round off any sharp edges from surface. Minimum surface preparation is Near White Metal Blast Cleaning per SSPC-SP10/NACE 2. Optimum surface profile is 2-3 mils. Prime and shoot UL on to any bare metal the same day as it is cleaned to minimize any potential flash rusting.
Aluminum:
Aluminum should be blasted with aluminum oxide or sand, and not with steel or metal grit. Excessive blasting may result in a warped or deformed surface. After blasting, wash aluminum with a commercially available aluminum cleaner. Allow to dry, then prime.
Brass and Copper:
Brass and copper should be blasted with sand, and not with steel or metal grit. Remove all dust and grease prior to applying primer.
Galvanized Surfaces:
Clean and degrease any contaminated surfaces before priming. Do not blast galvanized surfaces with an abrasive grit. An adhesion test is recommended prior to starting the project.
Fiberglass Reinforced Plastic:
The gel coat should be lightly blasted or sanded with 80 grit sandpaper and cleaned.
Plastic Foams:
Enhanced adhesion is obtained when the foam is mechanically abraded. When coating polystyrene, do not use a solvent-based primer.
Textiles, Canvas, Fabrics:
Adhesion to most fabrics, geothermal membranes and textiles does
not require a primer.
Stainless Steel:
Stainless steel may be grit blasted and degreased before priming. Some stainless steel alloys are so inert that it is not possible to achieve a satisfactory bond. An adhesion test is recommended prior to starting the project.
New and Old Cast Iron:
Blast with a steel grit and degrease before priming. Old cast iron is difficult to prepare for a satisfactory bond. It can absorb oil and water soluble contaminants that will keep returning to the surface after the coating system has been applied and affect the coating system adhesion. An adhesion test is recommended prior to starting the project.
All Other Surfaces:
An adhesion test is recommended prior to starting the project.
