Adhésifs à chaud
Hot melt adhesives (also known as HMAs) are thermoplastic formulations that become malleable when heated and harden on cooling. They are used in a variety of applications, including bag sealing, carton sealing, and as a base layer for tapes. They are also commonly found as the main adhesive in book binding because of their versatility, durability and range of tack levels. Other uses include mirror mounting, cabinet fabrication and office paneling. Unlike water-based glues, they are non-toxic and environmentally friendly.
HMAs can be produced to meet specific performance needs, such as heat resistance and a low charring tendency. They can also be formulated to resist solvents and plasticizers and to have a narrow molecular weight distribution. They also have an excellent wetting ability that makes it easy to adhere to substrates of a wide variety of materials and to fill gaps.
Glue Adhesive factory produces several different types of hot melt adhesives. These can be modified to specific performance requirements by adding additives to the polymer mixture. Some of these are tackifiers, plasticizers and colorants. These additives can also alter the softening point, failure temperature and other properties of the product.
Other factors that influence a HMA’s effectiveness include its molten color, peel strength, and failure temperature. In addition, it is important to know how much time the glue can remain melted in the application tank before degradation occurs and charring begins. This is referred to as its pot life.
The most popular type of HMA is based on aliphatic copoly(amide). It has been optimized by adjusting the ratio of monomers and the number of diamines. This allows a greater variation in the desired melting temperature and opens up many new possibilities for manufacturing products that require an adhesive with a lower tack value.
The most common packaging materials for hot melts are tubes, sticks or cartridges suited to the application equipment. Larger hot-melt drum pumps are also available for high-volume applications. Compared to other forms of adhesives, HMAs have a very long shelf-life and can be stored safely at room temperature. They are easy to dispense, clean up and handle. Unlike other glues, they do not taint substrates and can be used across a wide temperature range. They also allow for higher line speeds and reduce maintenance and inventory costs.
Water-Resistant Adhesives
Wet glues, also known as traditional or cellulose adhesives, are a popular choice for paper labelling, woodworking and automotive industries. They provide a strong, reliable bond with many different types of materials and substrates. They are also an environmentally friendly and economical alternative to more traditional bonding technologies such as hot melt and cyanoacrylate. Wet glues are solvent-free and require minimal maintenance and handling, making them suitable for non-ventilated areas. They are also easy to clean off equipment, reducing downtime and improving productivity.
They are available in a variety of formulations and chemistries, including synthetic and natural-based options. Polymers are the backbone of each type of wet glue, providing both strength and chemical resistance. Plasticisers soften and improve flexibility, whilst stabilisers prevent degradation over time. Other ingredients help to modify the processing and bonding properties of the glue, such as thickeners and preservatives.
In the past, animal-based glues were commonplace – but these are now being replaced by more environmentally friendly alternatives. For example, protein-based wet glues are made from waste animal by-products like collagen – which is washed and soaked before being cooked to form raw glue. The glue is then treated with chemicals and heated again until it reaches a specific viscosity.
The resulting liquid glue is then moved to a tank for further treatment, with filtering used to eliminate impurities and stabilisers added to preserve the glue over time. Once the wet glue has been treated, it can then be pumped into bottles ready for use.
Unlike the molten hot melt glues, these wet glues cure as they react with moisture in the air or on the surface of the substrate. This curing process produces a tough and durable bond that is resistant to water, oil, grease and many chemicals. They are also formulated to be cold and condensation water resistant, with the ability to withstand freezing temperatures – making them ideal for glass bottle labelling in the beverage industry. The adhesives can be applied as a spray, foam, contact, or pressure sensitive, and are available in a wide range of sizes and styles to suit many applications.
Fast Drying Adhesives
Glues, adhesives, and sealants are essential materials for bonding and joining surfaces together. They come in a variety of forms, each with their own properties and applications. Understanding how these materials are made can help you select the best one for your needs. The manufacturing process of glues and adhesives is complex, involving several procedures and raw materials. These can be natural or synthetic and may include preservatives and thickeners. The final product should also be able to resist corrosion and moisture.
Some of the most common adhesives are cyanoacrylate, epoxy, and silicone. These glues are used in many different applications, from woodworking to jewelry making and electronics. These adhesives are very quick to dry and are very strong. They are available in both liquid and gel form, and some types can even be used on metals.
The first step in the production of glue is to remove water from the liquid material. This can be done through a number of methods, including infrared drying or a circulating air oven. Once the glue is dry, it can be poured into a container and packaged for sale. It should be stored properly to avoid spoilage.
There are several companies that produce glues in the US. These include Henkel Ag & Co Kgaa, 3m Company, Fuller H B Co, and Franklin International. The IBIS World industry profile provides a snapshot of these and other companies in the US Adhesive Manufacturing industry. It includes a comprehensive list of industry trends, market size, segmentation by product, revenue and profit, as well as key statistics such as company address, years of establishment, and employee size.
In addition to industrial adhesives, some manufacturers offer specialized products for specific applications. For example, Cotronics Corporation manufactures high-temperature and ceramic adhesives. The company also produces a range of potting and coating materials. Another company, Panacol-Elosol USA, makes UV and visible light curing acrylic adhesives for electronic assembly. The company also offers custom and thermal solutions for a wide variety of applications. All of the company’s products are produced through a rigorous quality assurance process.
Versatile Adhesives
The glue industry has seen a number of innovations and improvements in recent years. Many manufacturers have begun to use adhesives that are stronger, more flexible, or biodegradable. Many of these new products can also be applied at room temperature, so they are safer for both manufacturing employees and the environment. Some of these new adhesives can even replace more traditional fastening methods such as sewing and mechanical fasteners.
These newer glues are often designed to bond different materials together, and they can also be used to seal cracks and holes. These adhesives are usually formulated to be resistant to moisture, heat, and chemicals, making them ideal for a wide range of applications. They are also easy to apply, and they can be dispensed precisely where needed by using a machine or by hand.
Glues are typically categorized by their method of adhesion, followed by whether they are reactive or non-reactive. Reactive adhesives contain polymers that chemically react with other substances to harden. These types of glues can be used on a variety of surfaces, including metals, plastics, and wood. Some examples include cyanoacrylates, epoxy glues, and urethane adhesives.
On a more basic level, most glues consist of water and polymers. Water is added to glues during the manufacturing process to prevent them from drying out too quickly. This water is then evaporated, leaving behind the polymers to form a strong bond with other substances. Some of these glues are also formulated with preservatives and solvents to protect them from bacteria and to make them easier to work with.
Adhesives are a valuable tool in many industries, from food processing to furniture manufacturing. In addition to providing a strong bond, these adhesives can help reduce costs and improve productivity. For example, they can be used to replace mechanical joints in transportation vehicles such as cars, buses, and truck trailers, resulting in lighter weight and a more efficient use of fuel. They can also reduce noise and vibration in passenger vehicles, making for a more comfortable commute or secure cargo transport. The use of these versatile industrial adhesives can also reduce the amount of material used in products, allowing for a smaller environmental footprint.
