At the moment, the best alternative available for edgebanding in terms of quality is reactive PUR hot melt adhesives. When strong adhesives that can make a bond without showing a visible line and have exceptional resistance to heat, cold, water, and chemicals are required, PUR hot melts are the best choice.
In the furniture business, edgebanding wood-based panels with various edgebands has long been a standard procedure. Adhesive technology has particular problems because of the large range of materials it works with, high standards for appearance, and technological developments in engineering. In the creation of contemporary furniture, the edgebanding quality is becoming increasingly significant in determining the furniture piece's overall quality. The end user anticipates a faultless, almost undetectable glueline.
Modern thermoplastic adhesives that respond to moisture ensure excellent adherence and a professional finish when edgebanding projects. Just as important as rapid adhesive curing for instantaneous downstream processing and superior heat resistance and lifespan is a broad range of adhesion to a variety of edgeband materials. In kitchen and bathroom applications, PUR hot melt adhesives are renowned for their capacity to satisfy the most exacting standards for a seamless bondline appearance and durability against heat, moisture, and chemicals.
● Adhesives that melt quickly react with the moisture in the substance they are joining.
● For automotive industry, furniture production and paper processing
● There is a wide variety of bonding techniques available, ranging from edgebanding to profile wrapping.
● Works wonders with wood, HPL, PVC, veneer, extruded/calandered, Duroplastic, and thermoplastic edges.
● Heatmelt that reacts and forms an invisible adhesive bond.
PUR hot melt adhesives may be applied to roller and nozzle applicators, as well as throughfeed lines at different rates. To prevent any possible chemical reactions brought on by contact with metal, every part of the melting and application units that comes into contact with the adhesive must be covered with a non-stick substance. Additionally, a non-stick coating will greatly simplify cleaning.
In order to prevent overheating and undesirable secondary reactions, proper temperature control is required in the melting and application units. Overheating the adhesive temperature above the allowed range usually causes the melt's viscosity to rise quickly due to a thermal crosslinking process called the allophanate reaction, which is heat-induced and moisture-independent.
Finding the ideal hotmelt adhesives for edgebanding and joining various materials to wood-based panels has received a lot of attention in recent years. Although EVA is generally regarded as the most user-friendly alternative, there is a risk that the finished product may come into contact with steam, heat, or moisture. Adhesives made of polyolefins function better and provide better stability during melting. Nevertheless, there isn't a product on the market right now that can perform better than a polyurethane-based solution if you want a strong bond that is heat-and water-resistant.
