Chemical Resistant Coatings
Chemical Resistant Coatings with Chris Mathson and Wayne Jobling from Resimac.
Protective systems for the energy and Oil and gas sectors
Wayne and Chris are product and technical managers. The default coating that they usually talk about is 511 UCEN.
511 UCEN:
Suitable for permanent immersion; chemical storage, and secondary containment: chemical bunds
Key Properties:
- Brush and roller application
- Plural feed airless spray
- High build, 2-coat application
Chemical Resistance:
- Hydrochloric acid (HCI) up to 38% concentration
- Sulfuric acid (H₂SO₄) up to 98% Concentration
- Sodium hydroxide/Caustic (NaOH) up to 50% concentration
- Alcohols, amines, fuels and solvents
Ensuring the correct system is selected
Ask Key Questions:
- What is the issue I am trying to solve? What are the substrates I need to coat?
- Steel, concrete, GRP, etc., a mixture of substrates?
- Are there inherent structural issues that require resolving prior to coating?
What are my operating conditions?
- Chemicals and concentrations
- Operating temperatures and pressures
What are my constraints?
- Time limitations to carry out the work/return to service
- Weather issues, i.e., ambient temp, moisture
- Limited ability to correctly clean and prepare the area
- How long do I need it to last for?
Once we have the proper recommendation and specification, all items need to reviewed and talked about. All the different Resimac coatings have specification sheets for you to follow. There are a range of solutions. What is the problem, and what are you trying to fix? There are solutions.
When it comes to chemical resistance, the Resimac coatings can be applied to other areas that have a chemical exposure. (Short-term exposure)
Questions:
- What are some different factors that might change a surface preparation requirement?
- Can these coatings be spray applied, or are they all roller applied?
