Purpose 

DMBA is a group with both hydroxyl and carboxyl groups, a unique multifunctional hindered diol molecule, which has better solubility than DMPA in different solvents,
As a chain extender and hydrophilic agent, DMBA has been widely used in the production of waterborne coatings, waterborne adhesives and waterborne leather finishing agents for waterborne polyurethane systems.

Package

25kg aluminum foil bag with carton or according to user requirements.

 storage 

Require airtight storage in a cool, dry place. When stacking, place a 10cm thick wooden board under it, 50cm away from the wall.
