What is the reason why EVA hot melt adhesive does not stick? Some time ago, a customer asked us why we couldn’t stick books firmly when bonding. Through this small case, we will answer the question: What is the reason why hot melt adhesive does not stick?
1、 Insufficient use of hot melt adhesive causes delamination or non adhesion: Some manufacturers use less material to save construction costs, and the materials to be bonded are too heavy, resulting in insufficient bonding strength. At this point, simply increasing the amount of glue is sufficient to solve the problem.
2、 Degumming or non sticking caused by incompatibility between hot melt adhesive and materials: Check if the debonding or non sticking is due to incompatibility between the type of hot melt adhesive used and the composite material. Some materials, especially those containing plasticizers, can undergo chemical reactions with hot melt adhesive, affecting its viscosity. If it is caused by material compatibility, simply choose a hot melt adhesive that is compatible with the material. For manufacturers, sampling and testing before mass production are very important!
3. The purchased EVA hot melt adhesive may have quality issues: If it is a quality issue, such as insufficient penetration of the hot melt adhesive, or the hot melt adhesive supplier should be held responsible. When purchasing again, choose a hot melt adhesive manufacturer with strong strength and guaranteed quality
Polyamide is a synthetic product with high tensile strength, which is very suitable for hot melt adhesives. The chemical process generates a highly effective ultra tight bond. Polyamide hot melt adhesive can be used for various applications and adheres to many surfaces; Some people even insist on using challenging PVC. Polyamide hot melt adhesive is […]
Hot melt adhesive particles are solid adhesives that are heated above their melting point before being applied to a substrate. According to the desired application, hot melt adhesive has various appearances and textures. They do not require a curing or drying period as they quickly solidify when cooled to the freezing point. Therefore, hot melt […]
The packaging industry is rapidly changing with fluctuations in demand from various industries. However, nearly 80 years after the invention of the first adhesive product designed to address temperature and humidity challenges, a fact still exists – all types of industries rely on hot melt adhesives. At the time of its invention, this multifunctional adhesive […]
What are the applications of industrial hot melt adhesive? Although most of us may not have come into contact with hot melt adhesive during the manufacturing process, it is one of the most commonly used adhesives in industrial manufacturing. Industrial hot melt adhesive is one of the most widely used adhesives in the market, and […]
