What is hot melt adhesive? Hot melt adhesive is a plastic adhesive. Hot melt adhesive is a type of glue, and the range of use of hot melt adhesive is also very wide, mainly for bonding after heating, and the bonding effect is very good. Poisonous and tasteless, it is an environmentally friendly chemical product.
1：PUR edge sealing products PUR edge sealing hot melt adhesive is called moisture curing reactive polyurethane hot melt adhesive. Adhesive Layer This is an inherent property of PUR adhesives. 2：PUR coated products The adhesion and toughness (elasticity) of PUR-coated hot melt adhesives can be adjusted, with excellent bond strength, temperature resistance, chemical resistance and aging
1：Two-component puzzle glue series Two-component splicing adhesive is a water-based polymer isocyanate adhesive (EPI adhesive for short), which is a two-component adhesive with a water-based polymer containing active hydrogen as the main agent and isocyanate as a bridging agent. 2：High frequency puzzle glue series Using the principle of electromagnetic induction, after being converted into a
What is Polyurethane PUR Hot Melt Adhesive？ PUR hot melt is different than traditional hot melt. It is dispensed in very much the same way, the adhesive is heated to a liquid state and applied to your materials and cools to 'stick' them together. But...this is where PUR hot melt is special. As it cools,
Carton sealing hot melt adhesive uses a hot-melt machine to melt the hot-melt adhesive into liquid, and then sends it to the surface of the carton through the throat and spray gun of the hot-melt machine, and the hot-melt adhesive is bonded after cooling. It can meet the requirements of carton sealing, and overcome the
The advantages of hot melt adhesives are mainly manifested in the following aspects: #1 Fast curing speed, good bonding strength and flexibility. Hot melt adhesives can cure and bond within a few tenths of a second to a few seconds, and have the characteristics of melting when heated, and bonding when cold. This enables packers
Adhesives Classification and Use Summary There are many types of adhesives, which can be divided into many types according to their ingredients and uses. Here, the classification and use of adhesives are sorted out from these two aspects. Classified by ingredients There are many types of adhesives. The more common ones are: urea-formaldehyde resin
PUR Hot Melt Adhesive Curing Principle PUR hot melt adhesive is divided into two levels: physical curing and chemical curing. First, make an introduction to PUR hot melt adhesive: PUR hot melt adhesive (Polyurethane Reactive) is called moisture curing reactive polyurethane hot melt adhesive. Commonly known as: PUR structural adhesive, PUR glue, reactive hot melt
What is Resin Glue Powder Used For Urea formaldehyde resin (UF) is a polycondensation of urea and formaldehyde into an initial urea formaldehyde resin under the action of a catalyst (alkaline or acid catalyst), and then forms an insoluble and insoluble final thermosetting resin under the action of a curing agent or auxiliary agent. The
Why does hot melt adhesive become carbonized in high temperature environment? After the hot melt glue machine is used for a long time, you will see a layer of black material around the glue tank. These are carbides. Many people do not know how these carbides are formed and what should we do to avoid
