By the way, which brand of woodworking glue is good and environmentally friendly?

Honey, I'm glad to answer it for you. To buy woodworking glue, I recommend white latex. Its main brands are Nippon Nippon, Dulux, China Resources, Carpoly, Sanshu Sanshu, Yijiang, Malone, Panda, Baita, Hangang, Jinshui, Venter and Sanjin Sanwei. White latex is a water-soluble adhesive, which is a thermoplastic adhesive polymerized by vinyl acetate monomer under the action of initiator. Usually referred to as white latex or PVAC emulsion for short, the chemical name of polyvinyl acetate glue is a milky white viscous liquid synthesized by acetic acid and ethylene and added with titanium dioxide (low-grade powder such as light calcium carbonate and talcum powder). ) and then by emulsion polymerization. I hope my answer can help you.
