Urea-formaldehyde resin glue overcomes the shortcomings of solvent-based phenolic resin, such as poor storage stability, easy discoloration, flammability, and high cost. It is mainly used for water-resistant plywood, fiberboard, etc..
Why use HB commercial hot melt adhesive glue pillows? Unlike the typical adhesives, these materials can be used on a wide variety of surfaces. These hot melts are usually formulated to be highly durable. A high-quality HB commercial adhesive can withstand the wear and tear of everyday life.
The composition of adhesives varies greatly depending on the source and use of the raw materials. The design of natural bonds is relatively simple, primarily one-component; Simultaneously, synthetic adhesives are more complex than the essential bonding substances.
Water-based adhesives (Water-based Adhesives) refer to the dissolving of water-soluble macromolecules into an aqueous solution of appropriate concentration or the dispersion of insoluble macromolecules in water by the action of surfactants into microparticles (emulsion).
Although both hot melt adhesive films and hot melt mesh films are used as thermal adhesives for lamination, what are the differences between these two types of films? Why is hot melt mesh film more popular than hot melt adhesive film? Here is a specific introduction for you!
Making hot melt adhesives is simple and easy. The raw materials can be found in your kitchen. Most people already have a variety of polymers at home. Some are synthetic, but others are made from natural materials. The base of hot melts is EVA, which is water-soluble and has a wide range of open time
