  • Adhesive Bonding of Wood Materials

    Credits: 4 PDH

    PDH Course Description:

    Adhesive bonding of wood plays an increasing role in the forest products industry and is a key factor for efficiently utilizing our timber resources. The main use of adhesives is in the manufacture of building materials, including plywood, oriented strandboard, particleboard, fiberboard, structural composite lumber, doors, windows and frames, and factory-laminated wood products.

    Adhesives are also used in the assembly of furniture and cabinets, manufacture of engineered wood products, and construction of residential and commercial structures.Adhesives transfer and distribute loads between components, thereby increasing the strength and stiffness of wood products.
