In part 1, we discussed a few of the industrial paints; In this article, let’s discuss some more industrial paints:
Polyurethane Coatings
These coatings are mainly used as topcoats in epoxy paint systems. These coatings fill a vital niche for high-performance applications over metal, concrete, wood, and plastic.
Benefits
- Weather resistance
- Excellent gloss durability
- Good chemical resistance
- Good solvent resistance
Limitations
- Two-component coating
- May cause skin irritation
Polyester Coatings
These are quick curing, glass flake reinforced, and high build coatings. Polyester coatings provide long term corrosion protection. It has very good resistance to water and moisture. The polyester coatings are dry to handle and can be applied in a film thickness of 300-1500 microns per coat.
Benefits
- Quick curing
- Easy application with airless spray
- Great mechanical strength
- Great water resistance properties
- Very good chemical resistance
Limitations
- Temperature-dependent
- Recoating interval of 2-12 hours
Vinyl Ester Coatings
These coatings are known for their good solvent and chemical resistance. These offer very good adhesion to both cleaned steel and concrete. The vinyl ester is effective against a wide range of chemicals. Its temperature resistance is also higher in comparison to other traditional paints.
Benefits
- Very good adhesion
- Good abrasion resistance
- Good chemical resistance
- Good solvent resistance
- Can be applied with normal airless spray
Limitations
- Its overcoating interval is min. 2 hours and max. 24 hours
- Limited shelf life
- Dependent on temperature during application
Inorganic Zinc Coatings
Inorganic zinc coatings are very resistant to different chemicals and especially solvents. They are used as primers and have the ability to provide cathodic protection. It acts as a protecting steel substrate and reduces the risk of having undercutting corrosion. Its multiple topcoats are used for offshore structures, ships, industrial plants, refineries, tanks, bridges, etc.
Benefits
- Very good solvent resistance
- Very high heat resistance
- High mechanical strength
- Good adhesion to cleaned steel
- Good re-coat ability
Limitations
- Requires humidity for curing
Organic Zinc Coatings
Zinc epoxy is used as a holding primer both at industrial plants and within shipping. It has quick-drying properties and the overcoating interval is relatively short. It also enables cathodic protection. It offers very good airless spray application properties.
Benefits
- Good corrosion protection Good adhesion
- Good mechanical strength
- Short overcoating time
Limitations
- Temperature-dependent
- Two-component material
- Dry heat resistance up to 120 degree Celsius
- Not acid and alkaline resistant
These are the different types of industrial paints. Now, as you are aware of the benefits and limitations of all the industrial paints, you can buy the one as per your requirement. You can get some of the best paints and coatings from our website moglix.com at an affordable price.
