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.

Starlike dendritic polymers modified acrylate resin coatings have good performances.
Water-based acrylate resin coatings use water as medium, itís 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 hasnít 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.

Excellent properties of organic light emitting device with dendrimer.
Advantages of OLED:(1)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-MD2 524/CYD-MK5654 etc.) in the production, driven voltage is 1V less than the compared samples and lighting efficiency increased by 46%.
