Effective application of dendritic polyurethane coating in top coating.
Background.
Coating for automobile,ship,airsapce, due to expose in the environment, such as water,high temperature,dust,smoke, moisture, dust, chemical corrosion and acid precipitation,coating surface will be destroyed.
Automobile industry use protective transparent coating in the coating surface to reduce the impact of exposure in the environment.,mostly transparent coating is acrylic resin,such as thermosetting acrylic resins based onpolyacrylic acid / melamine resin,gel coating epoxy resin or single or double component polyurethane coating in liquid or powder form.
Disadvantages of traditional coating:
Easily scratching, chipping or damaged due to cleaning and maintenance, easily being effected by weathering, environmental conditions, production and distribution process.
Improved performance:
(1)long-term weather resistance(2) self-cleaning and easy removal of dust(3) high scratch resistance (up to 6H pencil hardness)(4) high chemical resistance (more than 1500 times friction of methyl ketone B on surface without damage (5) hydrophobic (close to or more than 90 degrees to 100 degrees of the water contact angle (6) high gloss (92.2)(7) excellent gloss retention(8) long-term UV-protection performance (9) the sag resistance (presence of nanoparticles)(10) higher scratch resistance compared to the Ceramiclear (PPG, Pittsburgh, PA).Weihai CY Dendrimer Technology Co.

Dendrimer-based intaglio ink has excellent performances.
Background:
Common connect ingredients of Gravure inks: soybean oil, linseed oil-modified alkyd resins, etc.
Conventional problems: a high content of volatile organic solvents, which plays an important role in the ink transfer and delivery, graphic representation, ink curing and printability.
Improvement Objective: Reduce volatile organic solvent content in gravure inks.
Methods: Use appropriately modified dendrimer as adhesive for intaglio ink.
Improved performance: Reduce the volatile organic solvent in the ink, promote paper and ink fastness, have good storage stability,light color, and moderate curing time. Meet the drying performance, physical and chemical resistance properties and resistance to machine washing, at the same time, can effectively reduce the VOC content, reduced by 50%, and resistance to machine washing performance increased by 33%, drying time reduced by 9%, cleaning time decreased by 40%.Weihai CY Dendrimer Technology Co.

Dendrimer-based storage devices have good performances.
Existing non-volatile memory based on standard silicon processing have problems to achieve large-capacity, because their complex structure lead to the large size of storage unit. And also the processing costs, and the chip can not be miniaturized due to technical limitations. Dendrimer-based storage devices have the following advantages:(1) non-volatile property (2)high integration density allows the implementation of large capacity (3) manufactured at low cost by a simple manner(4) driven at low voltage and low current, which reduces power consumption.Weihai CY Dendrimer Technology Co.
