In December 2025, industry research showed that BCS (Ethylene Glycol Monobutyl Ether) has become a common solvent in both aqueous and oil-based coating systems due to its unique properties, but its application positioning varies significantly depending on the system. In oil-based coatings, although there are many types of solvents, most of which are cheaper and have stronger dissolving power, BCS is still indispensable. It can effectively solve the problem of film whitening in high-humidity environments and alleviate the biting of plastic paint substrates by strong solvents, making it a key component in oil-opening formulations and regarded as a "high-end luxury solvent". In the aqueous coating system, BCS is widely used with the advantage of "high cost-effectiveness". As a film-forming additive, it has both hydrophilic and lipophilic properties, strong dissolving power, moderate drying speed and good constructability. Compared with the slow drying of alcohol ester 12 and the high cost of DPM, BCS has strong demand in the mid-to-low-end industrial paint field. Although BCS has shortcomings such as strong odor and being prohibited in high environmental protection systems, its versatility has made it a stable position in the coating industry.
