For panel factories or furniture factories that use splicing adhesive, if white glue lines appear at the bonded joints after workers use the splicing adhesive, and paint cannot cover them, this will prevent subsequent processes from proceeding normally for the factory. So as a splicing adhesive manufacturer, below are the causes and solutions for white glue lines appearing after splicing:

First, from the perspective of the splicing process, the main possible causes of white glue lines on spliced products are as follows: 1. The processing precision of the panels to be spliced has defects (such as obvious saw marks, uneven ends, etc.), which can cause the adhesive to fill the defective areas and result in white glue lines. 2. Everyone should know that after applying the adhesive, to allow the adhesive to better penetrate into the wood, the splicing adhesive needs to be properly pressurized. When many factories apply insufficient or uneven pressure, the splicing adhesive also fails to squeeze out glue particles or glue lines. 3. The open time after applying the adhesive is too long, causing a film to form on the adhesive surface, and the resulting false adhesion phenomenon can also cause white glue lines.

The above relates to the splicing technique. It is also possible that the problem is caused by the wood itself. For some woods with looser grain (such as elm, willow, and some types of oak), white glue lines may appear due to penetration. Generally speaking, if white glue lines appear during production, the process should be improved. If the substrate itself is the problem, a small amount of pigment can be added to the splicing adhesive before bonding. Please consult your splicing adhesive supplier for the specific ratio. The above are the causes and some solutions for white glue lines appearing after splicing with splicing adhesive. We hope this is helpful to everyone.
