What is multilayer lamination with hot melt adhesives
Multilayer lamination hot melt adhesive is a thermoplastic adhesive that can smoothly bond the surfaces of multiple materials together. The most commonly used adhesive type is PUR hot melt adhesive (also known as PUR hot melt adhesive for flat lamination). Multilayer lamination with hot melt adhesives is mostly used in wood processing, furniture, decorative materials, RV manufacturing, and other industries. It is specifically used to cover different types of materials on the surface of large panels to provide protection, sound insulation, moisture resistance, fire resistance, and other functions.
What materials can be bonded using multilayer lamination with hot melt adhesives
The materials that can be bonded by multilayer hot melt adhesive are divided into bonding substrates and surface materials. The bonding substrates are: MDF board, solid wood board, WPC board, multi-layer board, wood plastic board, aluminum board, glass magnesium board, etc. The surface materials are: PVC film, PET film, PP film, paper, acrylic, fireproof paper, etc. Because the substrates of multi-layer lamination are large-area materials, the performance requirements for adhesives will be higher.
How to choose multilayer lamination with hot melt adhesives
When manufacturers or traders choose multilayer lamination hot melt adhesive, the most important thing is to understand what the substrate is to be bonded, followed by understanding the equipment parameters of the multilayer lamination, and finally understanding the temperature and humidity of the bonding environment. Of course, after selecting the hot melt adhesive, a small batch test must be carried out before normal production can be carried out.
Since different adhesive substrates have different permeability and bonding strength to adhesives, it is necessary to consider the differences in the substrates to select the appropriate adhesive. The parameters of multilayer lamination equipment are mainly related to the amount of glue applied, open time, glue viscosity, production efficiency, etc. The temperature and humidity of the environment mostly come from seasonal changes (manufacturers will divide them into regular versions, summer versions, and winter versions), which will affect the initial adhesion, open time, offline strength, curing time, etc. of the hot melt adhesive.
What is the application temperature of multilayer lamination with hot melt adhesives
The operating temperature of multilayer lamination with hot melt adhesives is 130-160°C. Too high a temperature will cause the hot melt adhesive to carbonize and the viscosity to decrease, affecting the adhesive bonding performance. Too low a temperature will cause the hot melt adhesive not to melt completely and the viscosity to increase, resulting in poor penetration of the hot melt adhesive.
How to choose a multilayer lamination with hot melt adhesive supplier
As a new type of adhesive product, multilayer laminating hot melt adhesive needs to be considered from the following perspectives when factories and traders choose suppliers:
R&D Capabilities
Due to the high technical content of PUR hot melt adhesive, only suppliers with independent research and development capabilities can continuously adjust the glue formula based on the actual on-site conditions of the factory.
Application experience
Different substrates are often used for multilayer lamination at the factory site. If the adhesive supplier lacks sufficient application experience, it will be unable to recommend the appropriate glue model for the manufacturing plant.
Production Capacity
The production capacity of adhesive suppliers is related to product delivery time, cost control, product quality, and supply chain stability.
Service capabilities
For buyers, the service capability of adhesive suppliers is not just one aspect of product delivery, but also covers multiple aspects such as after-sales processing, customization requirements, and communication efficiency.
price
Under the premise of not affecting the stability and performance of adhesive products, low price is one of the key factors that buyers consider.
How to Buy multilayer lamination with hot melt adhesives
If the amount of glue used is not large, you can choose to buy it directly from nearby traders or B2B online shopping platforms. However, if the amount of glue used is relatively large, factories or local buyers will generally choose to buy directly from hot melt adhesive manufacturers, which can not only get the lowest price, but also get product quality and technical service guarantees.
