Hot melt adhesives exist in solid form and are classified by different types of raw materials. Polyurethane (Polyurethane Hot Melt Adhesive) is a reactive type of hot melt adhesive for the base material. After cooling, there will be a chemical cross-linking reaction. Rubber-based pressure-sensitive hot melt adhesives are mainly used in packaging, labels ,metal back stickers and so on.
Reactive types of hot melt adhesives can bond a variety of substrates, including some difficult-to-bond plastics. These adhesives can handle all walks of life's toughest bonding applications. The hot melt adhesives is the best choose of high-speed processing, bonding diversity, large gap filling, rapid initial strength and less shrinkage.
DeepMaterial reactive types of hot melt adhesives have many advantages: the open time ranges from seconds to minutes, did't need the fixtures, long-term durability and excellent moisture resistance, chemical resistance, oil resistance and temperature resistance. DeepMaterial's reactive types of hot melt adhesive products are solvent-free.
Advantages of hot melt adhesive:
High production efficiency (shorter curing time)
Easy to realize the automate the process
Combines adhesive and sealant properties
Advantages of pressure sensitive hot melt adhesive
Long-lasting stickiness
It is a reactive hot melt adhesive based on polyurethane prepolymer. The adhesive is pressure sensitive and provides high initial strength after adding the part immediately. It has excellent reworkability, good bonding performance and is suitable for the opening time of automatic or manual assembly lines.
