Greetings,
Currently, I am trying to develop a new paint formulation. I already have in mind on what type of pigment and additive that I want to use. The problem is, I do not have a good idea on the type of binder to select. I have seen quite a lot of paint been commercialized, but I am worried that if the paint I buy on market will already have their own pigment and additive. If yes, then the uncertainty of what type of pigment they used will not give me a clear understanding on its formulation.
So, can anyone give me specific suggestion on the type of paint binder to buy? Probably the key words to find them will also be useful.
dear Wan Mohamad Ikhmal ;
what about using asphalt oil cut distillate with low sulfur content.
Dear Dr. Wan Mohamad Ikhmal,
you already have in mind on what type of pigment and additive that you want to use….and I think you also know the type of substrate and sspecific application.
Binders are what holds the pigments in place and binds all the ingredients of the coating together. All of these ingredients are what makes up a coating's protective attributes. Getting the correct ratio of binders in your coatings makes a big difference in it's appearance and durability.
Three main binders or resins which are most frequently used include: acrilic poilymers, alkyd polimers and epoxy polymers. There are other types of binders but those mentioned have a low VOC rating.
For more details regarding binder general characteristics and pros and cons, please see the useful notes by J. Parker at:

As usually at your disposal.... good work !!!

Thank you very much Dr. Pierluigi Traverso for giving such a helpful answer !! I am very much always eager to see your answer every time I ask a question ^^
Special thanks also to Dr. Mahmood H. M. for the suggestion !! :D
The best binder are epoksy resins with suitable hardner(s). But I found new paints that are based on e.g. polyaspargine resins.
