Dendritic polymers exhibit a high surface activity, at very low concentrations – critical aggregation concentration (CACs), they have the ability to aggregate in the water itself. With PAMAM generation increases, CACs reduces, molecular weight and structure has important impacts for the control of surface activity and CAC. Dendritic polymers are effective adhesion promoter for urea formaldehyde (UF) resin, it may increase the surface wettability due to its large number of surface group. End reactive groups at dendritic polymer chain can form large aggregation through its function when at very low concentrations. Formation of the polymer significantly decreases the surface tension of the aqueous solution. They form their surface activity in the air – water interface. Adding G3-NH3Cl in the urea-formaldehyde resin can significantly improve the adhesion of wood adhesives. Weihai CY Dendrimer Technology Co.
