Product Introduction

◆ Special Properties

DMBA is a multifunctional compound containing two primary hydroxyl groups and one carboxyl group, which makes the molecule have both alcohol and acid properties . The lipophilic carbon skeleton and hydrophilic functional group structure make it have unique solubility characteristics, and become an excellent extender and hydrophilic agent, which can be used as a synthetic water-based polymer system. DMBA has better solubility than DMPA in different solvents, and has better comprehensive properties.
