Adhesives are involved with almost anyone and anything. Adhesives in my country started in the 1950s. After entering the 1990s, the adhesive industry has developed
Hot melt adhesive is a plastic adhesive. Its physical state changes with temperature changes within a fixed temperature range, and its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product. Hot melt adhesives are easy to pack, transport, and store. The product is solvent-free, pollution-free, non-toxic and environmentally
1. Instant bonding The instant adhesive does not need heating and pressure when used, and has the characteristics of fast curing and high bonding strength. A 6.45 square centimeter adhesive surface can withstand enough tension to lift a small car. Such adhesives have greatly promoted the continuous production line. 2. Bonding of structural parts Structural
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
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
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
Precautions for Hot Melt Edge Banding Edge banding hot melt adhesive is a kind of thermoplastic glue specially used for edge banding of furniture panels. It has a wide range of uses in edge banding and is suitable for bonding various materials. What should I pay attention to when using edge banding adhesive? #1
Characteristics of EVA Hot Melt Adhesives EVA hot melt adhesive is a solid meltable polymer that does not require solvents and does not contain 100% moisture. It is a solid at room temperature, and it becomes a fluid and viscous liquid when heated to a certain temperature. The melted EVA hot melt adhesive is light
4 Simple Methods to Check The Quality of Book Binding Adhesive Glue How to distinguish the quality of book binding adhesive glue? As a manufacturer with 24 years of experience in R&D and manufacturing of hot melt adhesives, WINLONG will teach you how to distinguish its quality from several aspects. #1 First, you can use
10 common problems and analysis of edgebanding hot melt adhesive #1 Loosen after bonding a. The unqualified melamine seal at the bottom releases substances that cause degumming b. Unqualified PVC edge-sealing bottom coating (medium) is not compatible with hot melt adhesive c. The oily veneer edge is bonded with incompatible hot melt adhesive d.
