Polyurethane glue is a glue containing urethane groups and isocyanate groups in the molecular chain. The main chain of polyurethane is very flexible. Its biggest feature is the resistance to shock vibration and bending fatigue, high peel strength, especially excellent low temperature resistance. Existing glue comes out on top. Polyurethane glue has a simple process,
In order to avoid binding quality problems caused by adhesives, the adhesives for bookbinding should have good aging resistance, high and low temperature resistance, and stretchability. (1) Types of hot melt adhesives for bookbinding There are many kinds of adhesives used for bookbinding, of which the most used is hot melt adhesive. Synthetic resin type
60940 hot melt adhesive is a kind of polyurethane reactive hot melt adhesive. It needs suitable melting equipment and has high melt viscosity. It is suitable for high temperature working environment. 60940 Hot Melt Adhesive Product Parameter Details Product: Polyurethane reactive hot melt adhesive Physical state: solid Color: natural color Viscosity: 80000±20000cps at 150℃ Softening
Wood splicing, furniture, wooden doors, wooden utensils production, assembly, bonding, etc. need to use wood glue. At present, there are a lot of fake and inferior wood glue on the market. The inferior wood glue is cheap and often misused by some manufacturers. Once the inferior wood glue is used, it often causes heavy losses

⒈ Water-based glue is classified by material: Polyvinyl alcohol water-based adhesive, vinyl acetate water-based adhesive, acrylic water-based adhesive, polyurethane water-based adhesive, epoxy water-based adhesive, phenolic water-based adhesive, silicone water-based adhesive Adhesive, rubber water-based adhesive. ⒉ Water-based glue is classified by application: Construction water-based adhesives, packaging water-based adhesives, automotive water-based adhesives, shoe-making water-based adhesives, daily water-based
1. The water-based glue must be stored in a ventilated indoor environment at 5-40°C away from light. 2. The water-based adhesive is odorless, non-flammable, and has a yellowing resistance level of 4.5 or higher. It is suitable for light-colored materials and materials with high requirements for yellowing resistance. The glue brush can be cleaned with
The use of hot melt adhesive is very extensive, and the effect is also good. And does hot melt adhesive have formaldehyde, let's take a look now Does hot melt adhesive have formaldehyde? Formaldehyde-free. The hot melt adhesive is made of EVA resin as the main raw material. The material itself has no formaldehyde, so
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
Many people who use hot melt adhesives or want to know more about hot melt adhesives will have a question, that is, whether hot melt adhesives are resistant to high temperature, and how many degrees of high temperature can they withstand. Some irresponsible manufacturers or companies on the Internet will say that hot melt adhesives
