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 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.

Excellent properties of organic light emitting device with dendrimer.
Advantages of OLED1)light weight (2) easy operation with simple elements (3) good imagine quality, high color purity and dynamic image(4) low power consumption. The most important fault of OLED is the short life span, but life span increased by 100% if use dendrimer (CYD-MD1384/CYD-MK4514/CYD-MD2524/CYD-MK5654 etc.) in the production, driven voltage is 1V less than the compared samples and lighting efficiency increased by 46%.

Starlike dendritic polymers modified acrylate resin coatings have good performances.
Water-based acrylate resin coatings use water as medium, it’s an environment friendly coatings as VOC is little. The disadvantage is the high surface tension of water, it results in poor leveling property, slow drying, sagging, craterring,low gloss etc. Because of bad water resistance,
it hasn’t been used in automatic coatings. Dendrimers (CYD-CR111/CYD-CR236/CYD-CR486/CYD-CV11etc.) can offer more active crosslinking point to lower viscosity of coatings and increase leveling property and crosslinking density, thus getting curing film with better over-all properties.Weihai CY Dendrimer Technology Co. Ltd.-Professional Manufacturer for low cost dendritic polymers.

UV curable film performance of branched polyurethane acrylate
Dendrimers (CYD-CR111/CYD-CR236/CYD-CR486/CYD-CV11 etc.)have low viscosity and good adhesion, used in light curable acrylic polyurethane coatings formulations, their performance is complementary , thereby making coating performance more excellent. System with dendrimer has high functionality, cured film network has large crosslinking density and the film has high hardness, compared to unmodified polyurethane system, it has better coordination of the hardness and flexibility, therefore have better wear resistance, hardness increased 0.8 times, wear resistance increases 1.7 times. In addition, the dendrimer modified acrylic polyurethane UV coating, can be blended with a variety of active monomer to improve overall performance, while not affect its own flexibility and adhesion.
