Why are shoes easy to degum when changing soles? Some people who can make leather shoes talk about the skills of sticking the bottom and give a compliment!

There are many questions about the reasons for the degumming of shoes. First of all, you should consider the materials of soles and uppers, and then use corresponding materials with chemical treatment agents, including rubber or smooth EVA Modo and leather materials. Adhesive parts must be roughened, and the surface of adhesive parts must be roughened first, and then treated with chemical treatment agents of different materials. Then wipe it with PU glue. All materials must be wiped in place in all aspects. Generally, the glue must be applied for a second time. After wiping the glue, it must be dried in a high-temperature oven, and then pressed by a powerful press until the weight reaches 50KG, and the time shall not be less than 10 second. This will ensure that the shoes are not sticky.
