Which one among the following is commonly used as an 'anti-skinning agent' in paints?

Correct option is D

The Correct answer is (d) Polyhydroxy phenol. Polyhydroxy phenol is commonly used as an anti-skinning agent in paints. Anti-skinning agents are additives used in paints and coatings to prevent the formation of a skin or film on the surface of the paint when it is exposed to air. This skin forms due to the oxidation of certain components in the paint, which can hinder its application and affect the quality of the coating. Polyhydroxy phenol works by inhibiting the oxidative polymerization process, thus keeping the paint fluid and free from surface skin during storage. Information Booster: · Anti-skinning agents like polyhydroxy phenol help improve the shelf life and usability of paints, especially oil-based paints. · They are particularly important in preventing skin formation during the drying process in the presence of oxygen. · This ensures that the paint remains easy to apply and maintains its desired finish. · Other common anti-skinning agents include methyl ethyl ketoxime and butylated hydroxytoluene (BHT).
