Requirements for adhesives
The main characteristics that adhesives should possess are as follows:
Appropriate viscosity, good wetting property and fluidity, and ease of operation;
High bonding strength, with the cured adhesive layer having certain elasticity;
Good resistance to water, heat and aging;
Capable of curing within a short period of time under relatively mild conditions, without toxicity or strong irritation;
Low price and abundant raw material sources.
Adhesives commonly used in wood processing and furniture industry
Urea-formaldehyde resin adhesive
Simple to manufacture, easy to use, low in cost, with excellent performance, high bonding strength, good water resistance, heat resistance and corrosion resistance. It is often used in indoor-grade artificial boards.
Phenol aldehyde resin adhesive
Excellent bonding strength, water resistance, heat resistance, and weather resistance, suitable for outdoor-grade artificial boards
Melamine formaldehyde resin adhesive
High bonding strength, excellent water resistance, heat resistance, and aging resistance, and colorless and transparent.
Melamine-modified urea-formaldehyde resin adhesive
High bonding strength, excellent water resistance, heat resistance, aging resistance, and lower cost, mainly used for indoor-grade artificial boards and impregnated decorative paper.
Resorcinol formaldehyde resin adhesive
Water resistance, weather resistance, corrosion resistance and durability. Can be used for both heat curing and room temperature curing. Mainly used for building wooden structures, bonding curved components, finger-jointed boards or integrated materials.
