Greetings,
I'm planning to formulate a coating using several components. However, I am currently stuck in selecting an appropriate binder such as epoxy resin, acrylic and etc.
If you have any suggestion on a strong paint with less harmful effects on environment. Kindly share it with me. Thank you !
Dear Dr. Wan Mohamad Ikhmal,
I recently dedicated myself to the study of low surface free energy coatings (biocide-free) for naval use. With regard to the hull, the most used coatings (in eutrophic environments) are the silicone ones for their high antifouling power. For use in less biologically active seawater and for very fast boats, the perfluorinated coatings are used for high adhesion power, durability and hardness against impact.
My best regards, Pierluigi Traverso
Hi
I would recommend a coal tar Epoxy.
Refer to th Link:(https://www.corrosionpedia.com/definition/2523/coal-tar-epoxy)
Dear Prof. Khaled J. Habib ,
Thank you very much for your excellent suggestion. I have check out the coal tar epoxy and I have found that it possess a great ability to resist corrosion as a polymer.
My concerns is however, I found several statement suggesting that coal tar is a carcinogenic substance to us human. Since I planned on developing a coating for marine application, I worried about its safety issue especially on both us and the aquatic life.
May I ask, what is your thought on this? Is the negative effects can be considered negligible or vice versa.
Thank you :)
Thank you very much dear Dr. Pierluigi Traverso :)
Those are some excellent suggestions. I ll be sure to put them in my notes :)
Hi
I would recommend a solution of epoxy resin filled carbon-based material with a pH value, and the pH could be keep to some extend for long-term. I recently dedicated myself to this study.
Thank you dear Dr. Wei Hongyu for your suggestion :) I ll be sure to note it down
Dear Wan
I have used the coal tar Epoxy to shield metallic surfaces from corrosive media,i.e., seawater, acid solutions and so on, in sudies of corrosion behaviors of metallic samples in those media. I normally coat all surfaces of a metallic sample , including the edges, by the coal tar Epoxy except one surface, in order to conduct the study on that surface. I found out that the coal tar Epoxy is very effective of protection the other surfaces of th sample. The corrosion, accelerated, test is usually last not more than one hour according to the ASTM standard test. This allows me to predict the corrosion behaviors of different metallic samples in diverse corrosive media.
You have rraised a good research point as far as the long term effect of the coal tar Epoxy on human & aquatic life. One must study,investigate, to be sure about the effect of the long term effect of the coal tar Epoxy on human & aquatic life.
Dear Wan Mohamad Ikhmal
In the marine environment, epoxy coatings work best. Mechanical properties and resistance to environmental conditions can be designed using different hardeners, eg aliphatic or aromatic, short-chain or more complex. Epoxy coatings also withstand cathodic protection conditions that are ubiquitous in marine conditions.
