Initially, three manufacturing methods for multilayer boards were disclosed: the Clearance Hole Method, the Build Up Method, and the Plating Through Method (PTH).

Wood Glue Powder is formulated from powdered cheek aldehyde resin, reinforcing agent and curing agent.

Our company mainly produces urea-formaldehyde resin glue powder (pure raw powder), which is used in wood, carton, molded door panels, particle board, multi-layer board, MDF, laminate flooring and so on.

Melamine modified resin powder is mainly used for impregnating paper and producing decorative boards, but the shelf life of impregnating glue is shorter, usually only about one week, and the storage period of powdered products is longer, which is convenient for long-distance transportation.
