Listed below are the main applications for coatings and adhesives. Each of them has their own advantages and disadvantages.

Common coatings

The composition of many common coatings adheres to surfaces to components. In the past, adhesives consisted of solid components suspended in a solvent, usually methyl chloroform. Today, adhesives are more complex formulations containing pigments or solids that are applied through a carrier solvent. Inks and coatings adhere to a variety of target surfaces. A general understanding of how these coatings adhere to surfaces is important for formulators.

There are three major types of adhesives. One-component adhesives cure with heat or moisture in the air. Two-component adhesives cure by mixing two types of liquids, or two-component. Compared to hot melt adhesives, two-component adhesives offer a higher level of adhesion strength. The three main types of adhesives are described below. A quick cure adhesive is a fast-curing formula that binds two surfaces without the need for mixing or heating agents. A UV-curing adhesive has a high degree of UV sensitivity and can cure in the absence of oxygen.

High-performance adhesives provide the strongest bond between two or more surfaces. They can withstand surface movement, chemical exposure, shock, and vibration. They can also withstand extreme temperature changes. Depending on the application, high-performance adhesives can enhance the performance and life of products. These adhesives are highly engineered solutions that meet specific application needs. They are also available in custom formulations. The versatility of this technology makes adhesive coatings an ideal choice for a variety of industries and applications.

Common adhesives

The various types of coatings adhesives can be further divided into two basic categories – solid and liquid. Solid adhesives are those that must be melted before use and are characterized by a shorter curing time and fewer conditions. They are composed of a range of common materials, such as rubber, olefin, EVA, and PA. Reactive hot melt adhesives, on the other hand, have characteristics that enable them to cure quickly and are heat resistant. They also cure in air moisture and are often used for various target types. Several different types of adhesives may be suitable for different target types.

The converting industry uses many different types of coatings. Each type has its own unique characteristics and application methods. To make the most of your adhesive coatings, choose the type that best matches the type of equipment you have and the end-use requirement. The experience and market knowledge of ChemPoint can assist you in defining your specific needs. In addition to the wide selection of coatings adhesives, we also provide customized solutions to solve your application challenges.

An essential part of consumer electronics process control is ensuring that all adhesives perform flawlessly. The best way to achieve this is through in-process monitoring. It is impossible to guarantee a zero defect manufacturing process through late-process performance testing alone. Only through in-process monitoring can you guarantee perfect adhesion in your products. For instance, adhesive failures are often caused by variations in conditions. Understanding these factors is therefore essential to successful adhesion application.

Properties

There are two theories of adhesion: electrostatic and diffusion. Electrostatic adhesion is the dominant force in particle and biological cell adhesion. Diffusion theory suggests that adhesion occurs through inter-diffusion of molecules. Both theories apply to polymeric materials. Adhesion failure is caused by a combination of factors, including improper selection of substrate, incompatibility of surface, and insufficient surface preparation.

The fracture energy of coatings was quantified using the double cantilever beam test, a technique recently adapted for polymeric substrates. The adhesive fracture energy of sol-gel hybrid silica films on PC was measured and compared to that of pure silica with a Young’s modulus of 72 GPa and a density of 2.2 g/cm3. In addition, the film’s adhesive properties were preserved for many years under atmospheric conditions.

Applications

Most manufacturers use different types of adhesives to adhere materials together. For example, Adbond 8388-1 adhesive is ideal for laminate and wood veneer. The transportation industry uses various types of adhesives to assemble vehicles. They also play a critical role in wind energy. Some adhesives have special properties for particular surfaces. For example, Adbond 3409 adhesive cures quickly at room temperature. It has excellent adhesion and can withstand a variety of temperatures.

The applications of coatings adhesives are virtually endless. They are an integral part of our everyday lives, from a single sheet of paper to an entire wall. To develop a successful adhesive, a combination of different properties is necessary. MCP offers a variety of adhesives for most surfaces, including metals, glass, and ceramic. Many Rovene products are also available with pigments, fillers, and tackifiers for specific purposes.

As with any application, the durability of a coating system depends on its composition and its intended application. There are different types of coating systems, ranging from high-performance liquids to flexible granules. Each type of substrate will have different chemical, physical, and mechanical characteristics. As such, it is important to choose the right coating solution based on the application needs. ChemPoint has experienced chemists and market expertise that will help you determine the best adhesive for your specific needs.

Suppliers

Specialists in adhesives and coatings, such as Specialty Adhesives and Coatings are based in Memphis, Tennessee. These companies manufacture a wide range of adhesives for industrial applications, including hot melt adhesives, latex paints, and vapor barrier coatings. In addition to providing coatings, they also produce industrial adhesives for the construction industry. Depending on the application, these suppliers can provide a broad range of specialized coatings to meet the specific needs of a client.

The first question asked by many customers is, “How much does this product cost?” It is important to understand the cost structure of this type of product. There are several components to the price, including the solids and weight applied in the application process. Higher prices may require more wet or dry coating. However, low costs can often be offset by higher application costs. To make a sound decision, it is best to understand how different costs affect the price of different products.

Manufacturers who produce adhesives for industrial purposes can also benefit from the expertise and experience of a supplier. Parchem, for example, works with dozens of companies worldwide, and supplies them with raw materials and chemical ingredients for the production of their products. Their extensive product range allows manufacturers to select from a wide variety of products and packaging options. In addition, Parchem offers a full range of adhesive chemicals, including water-based and solvent-based products.

Durability

There are a number of factors that contribute to the durability of coatings adhesives. The adherends must be able to resist mechanical forces as well as the environment. These factors vary from highly protected sealed systems to outdoor environments that can be exposed to a wide range of environmental conditions. Furthermore, adhesives must maintain their bond strength even after being subjected to accelerated service conditions. To meet these requirements, adhesive formulators should first determine what products and processes their products will be exposed to.

Various tests were conducted on the adhesive properties of the epoxy resin coating at relative humidity of 98%-100%, 55 degC for 700 h, and 75 degC for 400 h. The peel strength test, dynamical mechanical thermal analysis, infrared spectroscopy, and energy dispersive X-ray spectroscopy revealed the development of the adhesive properties. The aging time indicated good time-temperature equivalence, and the adhesives were able to maintain their properties even under extreme conditions.

The adhesion strength of dry adhesives can be improved by coating them with a metal layer. Suh’s group presented nanohairy adhesives coated with a 4 nm layer of platinum, while Kim’s group reported the results of a six-nm gold layer. The metal coating improved the adhesion strength and mechanical properties of the coatings. They also studied the effect of metal on the adhesion strength of the dry adhesives.
