Effective application of hyperbranched polyester resin in the coatings.

• (1) hyperbranched polyester application in high-solids content coating.

• Compact molecular structure, three-dimensional spherical structure, not easy to tangle between moleculars, compared with same molecular weight linear polymers, its solution has low viscosity at a higher solids content. (2) hyperbranched polyester application in the UV curable coating. Introducing hyperbranched polymer into the UV curing system, can overcome some of the disadvantages of linear oligomers, such as severe shrinkage of film, diluent volatilizing, toxicity, etc.

• Thermosetting hyperbranched polyester with hydroxyl end groups, can control the crosslink density through the introduction of non-active/reactive end group. Light-curing coatings with acrylated polyesters, without adding photoinitiator, at a low intensity of UV irradiation, can cure film, and the film hardness, resistance to acetone, scratch resistance is good.

Hyperbranched polyester is widely used in the field of coatings.

• Hyperbranched polyesters can be widely used in coatings, either as direct additives, curing agent or as a coating material, have shown superior property compared with conventional additives . Hyperbranched polyester with double bonds nidified in the UV-curable coatings has outstanding performance. Such as for flexible material, showing excellent resistance to oxygen permeability, the PET and PP were increased resistance to oxygen permeability of 2.3 times and 15 times, in addition, it conglutinates well with the PET and PP packaging substrate. It has promising applications prospects.Weihai CY Dendrimer Technology Co.

• Polyamidoamine (PAMAM) dendrimer application in Coatings

• Characteristics of dendritic PAMAM:

• (1) Good hydrodynamics performance

• (2) Unique viscosity behavior, has promising application prospects in coatings.

• (3) Easy to forming-film, has promising application prospects in coatings.

• (4) Having a large number of active surface group, so functionalized and modified end group is more convenient.

• (5) A highly branched molecular structure determines its less prone to crystallization

• (6) Having a good thermal stability






Films made from PAMAM are a novel and efficient cell anode catalyst for methanol fuel.

• PAMAM-based film has good uniformity and the catalytic activity increases as the film generation enhanced. The catalytic ability of the film has been greatly improved compared to pure platinum catalysts, anti-drug capabilities have a greater enhancement, it’s a novel and efficient cell anode catalyst for methanol fuel. From "A direct catalyst for methanol fuel cell anode composite film and its preparation methods" Lin Shen, Luo Minghong, Zhang Xiaofeng, Fujian Normal University, Fuzhou, Fujian Normal University Technology Office Qishan campus, Application No. 200910112350.6. Weihai CY Dendrimer Technology Co. Ltd.-Professional Manufacturer for low cost dendritic polymers.






Hyperbranched polyester can significantly improve the many performance of PET processing.

• (1) hyperbranched polymer has greater impact on rheological performance of PET, when HBPE-OH addition level is 0.5%, the torsion decreases by 60%, in 10% of the added amount can decrease by 77%; (2) HBPE/PET mixing system has good thermal stability to meet the general using conditions and under the high temperature processing, PET will not degrade though with hydroxyl terminal groups; (3) Through SEM, it proves that HBPE-OH can bring brittle-ductile transition to PET material. From "Research on PET blending modification by hyperbranched polyester " Ji Lianqin, Beijing Institute of Technology 2010 Master Thesis. Weihai CY Dendrimer Technology Co. Ltd.-Professional Manufacturer for low cost dendritic polymers.






Effective application of hyperbranched polymers in the dyeing and finishing industry.

• Hyperbranched polymer characteristics: (1) the precise molecular structure; (2) a high degree of geometric symmetry; (3) a large number of functional groups; (4) cavity in the molecule; (5) relative molecular mass controllable; (6) nanometer size molecule. These characteristics determine the physical and chemical properties of hyperbranched polymers: (1) excellent rheology; (2) the unique viscosity property; (3) good solubility; (4) low surface tension; (5) glass temperature drops; (6) easy film forming; (7) not crystallization; (8) unique density and density distribution; (9) the unique refractive index increment. Hyperbranched polymers has been widely used in the dyeing and finishing industries due to its characteristics and physical properties. (A) cationic modification of cellulose fibers; (2) inkjet printing ink; (3) dyeing carrier in polypropylene fiber body (4) coating agent; (5) efficient anti-staining agents and leveling agents; (6) dispersion of "microcapsule" dye; (7) carpet scale inhibitor; (8) dyeing wastewater treatment agent; (9) fabric water repellent finish; (10) antimicrobial finishing of cotton.
