| Abstract: | The polycon method includes three-stage densation reaction, with low urea/formaldegyde molar ratio to decrease the content of the free formaldehyde and improve propertie of the product. The polyvingalcohol and melamine are added to improve the water-resistance and heat-resistance of the urea-formaldehyde resin adhesive. |
