In the Organic Coating industry, there are two groups of materials. One group is the water loving (Hydrophilic) group of substances. The other is the Oil loving (Lyophilic) substances. These two separate group of substances arise due to their polar or non-polar nature.
Usually a water loving or polar substances contain oxygen. They contain a shorter hydrocarbon entity in them and oxygen carrying groups like Acids, Alcohols, Aldehydes, Ketones, Esters and so on. Their molecules need not be smaller and they could even be polymers like Starch, Carbohydrates, Carboxy Methyl Cellulose. (Examples of Polar Substances : Acetic Acid, Methyl Ethyl Ketone, Acetaldehyde, Ethyl Alcohol, Oxalic Acid, Formaldehyde, Starch, Glucose, Sucrose etc).
In wide contrast, the Non-Polar substances may or may not contain oxygen and have larger Hydrocarbon chains. The examples are petrol (n-Octanes), Kerosene, Diesel, Coconut oil, Palm Oil etc.)
