Usage: DMBA is a new Amyl carboxylic acid with two active hydroxyl methyl groups, so it can be used as synthesis of water-based polymer system which can be widely served in soluble polyurethane,polyester and epoxy resin and other aspect.  

   It is regarded as a new kind of environment-friendly chain extender and inner emulsifying agent.When producing waterborne polyurethane adhesive, there is no need to add any organic solvent and the organic residue is zero. Then it will solve a series of  trouble of using DMPA, such as high melting point, slow dissolving, long reaction time, high energy Consumption, poor properties of products, using organic solvent and big organic residue. It also can be used in producing water borne epoxy resin ,polyester and other polyester.

    At present, DMBA is the best and multi-purpose functioning additive (hydrophilic chain-extender)in waterborne polyurethanewater-dilutable resinwater based coatingswater-based paint and other water based products.

As a monomer, in the modifying process, there is no need to add any other organic  solvents (instead of water). The performance will be even simpleprocess, stabler performance and  best effect. (National Patent Product,  Patent Number: 201210333925)
