Edge-gluing adhesive product series offer strong adaptability for various integrated wood processing equipment: high-frequency machines, ambient-temperature cold-press wheel-type panel gluers, main panel gluing lines for fragrant materials, manual fixtures, etc.

Edge-gluing adhesive products are specifically differentiated and applied for various solid wood species: oily hardwoods, hardwoods, and medium-hardwoods, such as: teak, rosewood, wengé, hard maple, ash, Chinese oak, white ash, white oak, red oak, rubberwood, poplar, pine, China fir, etc., to meet the strength requirements of different materials.

All edge-gluing adhesive series products meet E0/F★★★★ environmental standards and are manufactured with no added formaldehyde. Bonding strength is tested according to the Japanese JAS cold water immersion delamination and boiling water immersion delamination test standards. When paired with specialized adhesive application equipment, they meet the refined production processes and high-efficiency capacity needs of factories — safe, stable, and efficient!

Common Problem Analysis

Glue-line cracking at the ends of glued panels after storage for a period or shipment to different regions

Problem Causes  

• Moisture content related. If the moisture content during panel gluing is high, 14-16%, over time or when placed in a drier area, significant internal stress changes occur as the moisture content changes, leading to wood cracking or cracking at the glue line;

• The gluing surface is not smooth enough, with saw marks or planer skip marks. After pressing, the recommended surface bonding strength cannot be achieved. The internal stress changes in the solid wood then cause cracking due to insufficient bond strength;

• The proportion of hardener (cross-linker) in the edge-gluing adhesive is too low or insufficient, resulting in inadequate bond strength at the joint. The joint strength is less than the internal stress strength of the solid wood itself, making it prone to cracking at the glue line;

• The adhesive strength does not match the wood species; the correct adhesive with the corresponding strength requirements was not selected.

Solutions  

• Control the moisture content of the solid wood during gluing to 10-12%. It is recommended to control it to 8–10% to avoid significant stress changes later that could lead to cracking. Before further processing, wrap the glued panels with film to prevent moisture absorption and regain.;

• Ensure the gluing surfaces are smooth and flat during panel gluing, free from any saw marks or planer skip marks, ensuring the gluing surfaces are clean and even;

• Regularly check the ratio of the main edge-gluing adhesive component to the hardener daily, using precise measuring tools for proportioning;

• Before applying adhesive to different wood species, first conduct strength tests; only proceed with large-scale application once the strength requirements for that wood species are met.
