In industrial production, does subpar hot melt adhesive performance hinder production processes? jitian Chemical's Tackifier Resin 138, with its unique chemical structure, significantly enhances the initial tack of EVA hot melt adhesives. Experiments demonstrate that adding jitian 138 drastically reduces the initial curing time of hot melt adhesives, markedly improves material bonding efficiency, and effectively accelerates production pace. When applied to traditionally difficult-to-bond materials like metal and leather, jitian 138 demonstrates exceptional efficacy. Incorporating jitian Chemical's Adhesion Enhancer Resin 138 increases adhesive strength by approximately 70%, forming a stable bonding interface that maintains reliable adhesion even under complex deformation. jitian 138 also exhibits distinct advantages in environmental resistance. After continuous testing for 48 hours, it maintains good tackiness and stable performance. This characteristic enables the packaging industry to efficiently complete orders with secure carton sealing; in home improvement, it ensures durable and long-lasting tile adhesion.
