Coalescent additives are not a particularly large variety in the coatings industry, but they are indispensable. "Mobei Vision" selected dodecyl ester, the leading product of film-forming aids, for research, and made a brief market analysis. I hope it can help readers to have some understanding of the film-forming aid dodecyl ester. This unpopular and important product still has a certain investment space.
Film-forming aid is a volatile temporary plasticizer, which can promote the plastic flow and elastic deformation of latex particles, improve their coalescence, and can form films in a wide range of construction temperatures. The ideal film-forming aid should have the following characteristics: as a good solvent for polymer emulsions, it can reduce the minimum film-forming temperature of emulsion polymers; it has low solubility in water; it has certain volatility, and can stay in the coating film during the film-forming process. It plays a role in the film formation, and it all volatilizes after film formation, which does not affect the performance of the paint film; it does not affect the stability of the emulsion.
Taken together, dodecyl alcohol esters have very good volatilization rates for all flat and most semi-gloss architectural coatings. And dodecyl alcohol ester is water-insoluble and has good hydrolytic stability. In almost all emulsion systems, dodecyl alcohol esters showed excellent film-forming efficiency. Therefore, dodecyl alcohol ester is the most commonly used high-efficiency film-forming auxiliary in the architectural latex paint industry, especially for water-based architectural coatings, with a wide range of applications, good film-forming performance, and high environmental protection.
