How to Choose Wardrobe Edge Banding Adhesive: Key Tips
Customized wardrobe furniture edge banding adhesive is a type of adhesive specifically used for edge banding of artificial boards. It is a solvent-free thermoplastic adhesive. Furniture edge sealing hot melt adhesive belongs to industry-specific hot melt adhesive film products. According to its name, this is a type of hot melt adhesive film suitable for edge sealing of furniture and building materials products.
Types of Furniture Edge Adhesive
Furniture edge banding adhesive can be divided into three categories based on the different base materials
EVA (ethylene vinyl acetate copolymer resin) based hot melt adhesive can be divided into two types: with fillers and without fillers. The use of EVA as the base material is the most common production technology for furniture edge banding adhesive, but its main limitation is poor heat resistance. The environmental temperature for using EVA hot melt adhesive to seal the edges of panel furniture should not exceed 120 ° C;
POL YAMIDE (polyamide) based hot melt adhesive is a type of hot melt adhesive that has excellent heat resistance and fast curing characteristics, but its main disadvantage is that it is expensive.
HMPU (polyurethane) based hot melt adhesive is the best performing type of hot melt adhesive, ensuring high-quality board edge sealing. It is expensive and requires special usage methods.
Factors affecting the performance of furniture edge banding adhesive
The viscosity of furniture edge banding adhesive does not directly reflect the performance of the adhesive. In general, the higher the viscosity of furniture edge banding adhesive, the better its initial adhesive strength, but the worse its coating performance. Low viscosity hot melt adhesive has a smaller coating amount and better wetting performance. Some hot melt adhesives with low viscosity and fast curing speed may also have high initial adhesive strength.
The density of furniture edge banding adhesive is generally between 0.95-1.6g/cm3, and its density depends on the amount of filler.
The softening point and usage temperature of furniture edge sealant are indicators of its heat resistance. The higher the softening point, the less likely the furniture edge sealant is to melt. The softening point is also an important aspect of measuring the temperature resistance of panel furniture.
The opening time of furniture edge banding adhesive and the feeding speed of the edge banding machine
Characteristics of Furniture Edge Sealing Hot Melt Adhesive
When the furniture edge sealing hot melt adhesive is heated to a certain temperature, it transforms from a solid state to a molten state. When applied to the surface of the artificial board substrate or edge sealing material, it cools down and becomes a solid state, bonding the material to the substrate.
Furniture edge sealing hot melt adhesive has the following characteristics:
The solid content is 100% with void filling properties, avoiding edge curling, bubbles, and cracking, which can cause deformation, misalignment, and shrinkage of the adhered parts. Due to the absence of solvents, the moisture content of the wood remains unchanged, and there is no risk of fire or poisoning.
The fast adhesive coating and bonding interval are only a few seconds, and the saw head and cutting edge can be completed within 24 seconds without drying time. It can be used in continuous and automated wood bonding production lines, greatly improving production efficiency and saving factory costs.
Hot melt adhesive can be applied to wood for several times of bonding. If it does not meet the requirements due to cooling and solidification, it can be reheated for secondary bonding.
There are various options for furniture edge sealing hot melt adhesive, including high temperature, medium temperature, and low temperature.
Widely applicable for bonding various materials.
Precautions for using edge sealing hot melt adhesive
When the edge banding machine is not in operation, the temperature of the glue can should be lowered to around 150 ° C. On the one hand, this can avoid the carbonization phenomenon of hot melt adhesive under long-term use temperature, keep the glue can clean, and prevent blockage of the glue supply system and reduced heating performance; On the other hand, when resuming work, the rubber can be quickly heated up to the operating temperature.
In addition, more than 2/3 of the glue must be kept in the glue can, otherwise it will cause black carbonization around the glue can.
Regularly clean the glue tank and glue roller. Excessive carbonization around the glue tank and residue on the glue roller will reduce the performance of the heating system and glue supply system.
If you want to remove the residual glue from the glue can, before the edge banding machine stops working, when the glue is still in a melted state, place a T-shaped object into the glue, wait for the glue to completely cool down, and then reheat it. Since the glue at the bottom and around the can is melted by heat first, most of the residual glue can be removed with the T-shaped object. Then clean the residual adhesive with a 1:1 mixture of toluene and methylene chloride
Conclusion
Selecting the right edge banding glue is vital for achieving a professional finish and ensuring the longevity of your furniture. Whether you opt for no glue line options, temperature-resistant adhesives, strong bonding solutions, or PUR products, each type has its unique advantages tailored to specific applications.
