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
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
Question 1: After the PUR hot-melt adhesive is emptied, it is found that there are bubbles in the adhesive after continuous use for a period of time or after a period of inactivity, which affects the uniformity of scraping. Are there any bubbles in the hot-melt adhesive? 1. Replace the sealing ring of the rubber
1. Introduction of urea-formaldehyde resin powder (UF) It is a polycondensation of urea and formaldehyde under the action of a catalyst to form a urea-formaldehyde resin, and then under the action of a curing agent or an auxiliary agent, an infusible and insoluble resin adhesive - urea-formaldehyde glue is formed. Urea-formaldehyde resin can be processed
Furniture production involves the bonding of wood and wood, wood and plastic and other materials. Woodworking glue is used for the combination of wood and wood in furniture production. Finger joint, tenon joint, pressing, etc. are all inseparable from wood glue. In terms of form, there are liquid adhesives (water-based adhesives) and solid adhesives
