Factors that must be considered in selecting hot melt adhesive products.
With the increasingly stringent environmental regulations, environmental-friendly adhesives are gradually becoming the mainstream of synthetic adhesive products, countries in the world are vigorously developing water-based and hot-melt solvent-free adhesives.
Hot melt adhesive is a kind of solvent-free plasticity adhesive. Its physical state changes with temperature in a certain temperature range, and its chemical properties remain unchanged. It has the advantages of pollution-free, rapid curing and wide bonding surface. It is also a kind of environmental friendly chemical product and has been developed rapidly in recent years. The hot melt adhesive is melted by thermodynamics, and the glue after melting becomes a liquid, which is sent to the surface of the adhesive through the hot melt glue pipe and the hot melt glue gun of the hot melt glue machine.
Factors that must be considered in selecting hot-melt adhesive products
1.Temperature resistance.
Different systems of hot melt adhesive have different temperature range. Mokang hot melt adhesive products can withstand high temperatures up to 150 degrees Celsius.
2.Bonding different substrates
Hot melt adhesives of different systems have different adhesion to polar or non-polar substrates and are suitable for bonding different substrates, such as plastics, metal wood and paper.
3.Chemical resistant medium
Different systems of hot melt adhesive have different chemical resistance. Mokang environmental spray glue can provide different types of hot-melt adhesive products.
4.Strength
Thermoplastic hot melt adhesive can obtain the ultimate strength immediately after cooling. When temperatures rise, they soften again. Moisture curing polyurethane hot melt adhesive exists in the form of thermosetting after moisture absorption and crosslinking, and the cured polyurethane hot melt adhesive can not be remelted.
5.Substrate surface treatment
The surface of the substrate must be clean to ensure no contamination. Corona or plasma treatment can improve the bonding performance of plastic interface, and metal substrate can enhance the bonding effect by pre-heating.
Bigger environmental protection hot melt adhesive spraying is synthesized by imported rubber, environmental protection heat-resistant resin, environmental protection solvent, high-quality flame retardant materials and special additives and other major raw materials, so that the product has the characteristics of environmental protection, non-toxic, small odor, strong adhesive performance, good flame retardant performance, high temperature resistance, not easy to powder, easy to spray, easy to operate and so on.
