Does poor performance of hot melt adhesive hinder the production process in industrial production? Jitian Chemical Adhesive Resin 138, with its unique chemical structure, can significantly enhance the initial adhesion of EVA hot melt adhesive. Experiments have shown that the addition of Jitian 138 significantly shortens the initial curing time of hot melt adhesive, improves material bonding efficiency, and effectively accelerates production pace. Faced with traditional difficult to stick materials such as metal and leather, Jitian138 exhibits excellent performance. Adding Jitian Chemical Adhesive Resin 138 can increase the adhesive strength by about 70%, form a stable bonding interface, and maintain reliable bonding performance even under complex deformations. In terms of environmental resistance, Jitian 138 has obvious advantages. Continuous testing for 48 hours, with good adhesion and stable performance. This feature enables the packaging industry to efficiently complete orders, and the carton packaging is firm; Ceramic tiles in the field of home decoration are firmly and durable to be pasted.
