CYD Dendritic Polymers-Wastewater Treatment Materials
Demulsifiers
Product Description
Dendritic polymers as "the fourth class of new polymer materials", are attractive to the scientific world and industrial circles. The novelty of these materials includes highly branched molecular structure, a large number of surface functional groups, void space in molecules, monodisperse molecular weight distribution and nanoscale dimensions. The structural characteristics of dendritic polymers lead to unique properties such as excellent solubility and dispersion properties, low melt viscosity and solution viscosity, difficult to crystallize and easy to form film, showing unparalleled nano features.

Dendritic polymers have good solubility and carry positive charges in aqueous solution; they neutralize the droplets with negative charges in oily water, and are more stably adsorbed on the oil droplets due to its lipophilic carbon chains of organic polymer, thereby achieving the purpose of demulsification; dendritic polymers also can lower the viscosity of the system.
Excellent properties of dendritic polymers as demulsifiers
· Good water solubility and oil solubility;
• High efficiency of demulsification;
• Neat oil-water interface;
• Good universality;
• Less dosage and secondary pollution free.

Dendritic polymers can be used in many ways: dendritic polymers’s high functionality of end groups, such as hydroxyl, carboxyl and carboxylate salt, have strong adsorption capacity of pigment, showing good stability and dispersibility; what’s more, dendritic polymers being partially modified with long-chain fatty provide steric hindrance to prevent pigment molecules aggregating. Dendritic polymers can be used as novel dispersants by using the special viscosity behavior to prepare high solid coatings.
Excellent properties of dendritic polymers as pigment dispersants
· A large number of anchoring groups to increase the pigment dispersion and adhesion; steric effects make pigment stably dispersed;
· Good dispersion properties for organic and inorganic pigments; can prevent sedimentation and solve the problem of inorganic pigments floating;
· Modified dendritic polymers have certain extinction performance and no need to add matting agent, it can be well applied to semi-gloss top coatings and floating coatings of the car, and shows very good performance to prevent sagging. It can be used for industrial marine coatings, container coatings, outdoor steel thick film coatings;
· Good control of the pigments is favorable to control chromatic aberration among different batches and construction conditions.
