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

• 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

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.

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. From " Development of
