[0002] Water-soluble phenolic resin adhesive is the most important type of insoluble phenolic resin glue. The free phenol content in its components is low (generally <2.5%), which is less harmful to the human body. At the same time, the use of water-soluble phenolic resin can save a lot of organic solvents and is easy to clean during the gluing operation. Therefore, it is widely used in the wood processing industry. This adhesive is mainly used for gluing wood. In the water-based phenolic resin metering structure, a metering structure is required to better fill it into the container.
