Adhesives are used almost everywhere in the manufacturing industry to keep things together. Having a reliable adhesive will make a difference when attempting to bond surfaces. Each type of adhesive has its unique characteristics, which may make one adhesive more suitable for your current application than others.
Water based adhesive
Commercial water-based adhesive, also known as white adhesive, has a wide range of uses. Although the emergence of water-based adhesives may initially remind you of art and handicrafts, this industrial strength adhesive holds a place in modern industrial manufacturing.
Advantages of using water-based adhesive
Environmental Protection
Compared to other adhesives, water-based adhesives have; The VOC (volatile organic compound) content is lower, making it safer and more environmentally friendly to use. Additional benefits: Water based adhesive is easy to clean and has minimal odor!
Easy to apply
Modern water-based adhesives are both fast and easy to use – without the need for heating or mixing! Unlike solvent based adhesives, water-based adhesives do not clog when dried, which means they are suitable for rollers, spray guns, and immersion adhesives.
Cost effectiveness
The production cost of water-based adhesives is lower and requires less safety equipment, such as additional ventilation to remove them; VOC Steam.
Widely used
Water based adhesives can be used on almost any porous or semi porous surface, including paper, cardboard, plastic, wood, metal films, as well as natural and synthetic materials. The popular uses of white glue include packaging, binding, hard box manufacturing, wood bonding, lamination, graphic art, food and beverage packaging, general assembly applications, and box and carton sealing.
Challenge of using water-based adhesives
Drying time slower than hot melt adhesive or solvent based adhesive
Lower water resistance than solvent based adhesives
The possibility of freezing at low temperatures
EVA hot melt adhesive
Hot melt adhesive is a polymer adhesive that does not contain solvents or water. Their fast drying time and extremely high adhesive strength make them one of the most versatile industrial adhesives.
Advantages of using EVA hot melt adhesive
Quick drying
EVA hot melt adhesive dries very quickly. According to your application, you can use wax, plasticizers, and diluents to change the opening time, fluidity, and viscosity of the glue.
Strong Key
Known for forming strong bonds, certain types of hot adhesives, such as PUR (polyurethane reactive adhesive), can produce up to; 1,000 The adhesive strength of the pound. After the glue solidifies, hot melt adhesive will produce permanent fixation. Hot melt adhesive is usually very flexible and very suitable for heavy-duty applications.
Widely used
Hot melt adhesive can adhere well to various surfaces, including non porous substrates that are difficult to bond. If you find it difficult to stick things together, it may be time to remove the industrial hot glue! Due to its versatility, hot melt adhesive is used for various manufacturing purposes, including binding, packaging, woodworking, and construction.
Easy to apply
Hot melt adhesive is usually applied with an applicator, so there is no need to mix it! Depending on your application, the glue can also be used at higher or lower temperatures, allowing it to work both indoors and outdoors.
Challenge of using EVA hot melt adhesive
Disposable use
The glue will not penetrate the substrate and can form a bonding line
The shorter opening time makes it less tolerant than other adhesives
For most terminal packaging operations, adhesive carbonization is usually the main cause of most downtime events. Once EVA hot melt adhesive carbonization occurs, it will be difficult to clean thoroughly without taking extreme measures. Even after flushing, charcoal may still stick to narrow corners and continue to cause issues that affect normal operating time and […]
The role and key elements of bookbinding adhesive in binding are the key to the quality of bookbinding! Hot melt adhesive becomes brittle when cooled, the back adhesive layer is not smooth, and insufficient penetration of the adhesive liquid leads to non stick properties. These are the issues that most books and publications face when […]
Why does pearl cotton hot melt adhesive have wire drawing? During the process of gluing pearl cotton with a drum hot melt glue machine, some customers may find that the hot melt glue has a wire drawing phenomenon. The wire drawing of the hot melt glue not only affects the construction efficiency, but also affects […]
Direct answer:Hot melt adhesive granulesAfter absorbing water, the machine may experience bubbling of the melt adhesive, white spots on the adhesive layer, and decreased adhesion. In severe cases, the entire pot of adhesive may be scrapped Hot melt adhesive particles are hydrophobic but porous particles that will slowly absorb moisture after prolonged exposure after opening. […]
