Hot-melt adhesive (HMA), also known as hot glue, is a form of thermoplastic adhesive that is commonly sold as solid cylindrical sticks of various diameters designed to be applied using a hot glue gun. The gun uses a continuous-duty heating element to melt the plastic glue, which the user pushes through the gun either with a mechanical trigger mechanism on the gun, or with direct finger pressure. The glue squeezed out of the heated nozzle is initially hot enough to burn and even blister skin. The glue is sticky when hot, and solidifies in a few seconds to one minute. Hot-melt adhesives can also be applied by dipping or spraying, and are popular with hobbyists and crafters both for affixing and as an inexpensive alternative to resin casting.
Hot-melt adhesives are as numerous as they are versatile. In general, hot melts are applied by extruding, rolling or spraying, and the high melt viscosity makes them ideal for porous and permeable substrates. HMA are capable of bonding an array of different substrates including: rubbers, ceramics, metals, plastics, glass and wood.
Today, HMA (hot-melt adhesives) are available in a variety of different types, allowing for use in a wide range of applications across several industries. For use with hobby or craft projects such as the assembly or repair of remote-control foam model aircraft, and artificial floral arrangements, hot-melt sticks and hot-melt glue guns are used in the application of the adhesive. For use in industrial processes, adhesive is supplied in larger sticks and glue guns with higher melting rates. Aside from hot-melt sticks, HMA can be delivered in other formats such as granular or power hot-melt blocks for bulk melt processors. Larger applications of HMA traditionally use pneumatic systems to supply adhesive.

Drivers:
High demand in DIY applications
HMA can bond to a wide variety of materials and surfaces such as ceramic, fabric, papers, cardboard, metal, and plastics, which makes them suitable for DIY applications. Although DIY is popular in developed economies such as North America and Europe, whereas in emerging markets such as India, UAE, and Turkey it is a relatively new concept. The DIY applications include craft, woodworking, general goods packaging, and others. The stick form of HMA is widely used in these applications because of its ease of use and the availability of HMA guns. The DIY approach is very common in the US and European countries, where labor and installation costs are high, in comparison to the emerging markets such as China and India Hot melt systems are cost-effective in terms of floor space and labor requirements. This is most likely the result of eliminating the costs of operating large drying and curing ovens and pollution control equipment. Solvent recovery and incineration equipment, which are inevitable for solvent-based systems, are also eliminated from hot melt systems. This ultimately reduces installation and maintenance costs of these systems, surging their demand in DIY applications.
Change from Solvent Adhesives to Hot Melt Adhesives to Promote Market
Hot melt adhesive (HMA) is expected to experience a high growth rate relative to the current solvent-based adhesive. Its advantages include high productivity induced by process automation, a wide variety of applicability, eco-friendliness, and re-adhesion possibility. As opposed to a solvent-based or water-based adhesive, these products allow a limited working space and have high-speed adhesion without a drying phase. The HMA's high-speed adhesion allows for production line automation. HMAs may not lose thickness; solvent-based hot melt adhesives during drying can lose up to 50-70% of layer thickness. Therefore, they have major economic benefits such as improving efficiency, reducing the amount of material usage generated by spread control, lowering labor costs, and others. These products demonstrate major advantages relative to conventional solvent-based adhesives that typically require evaporation and removal of solvents or polymerization to bind substrates together. For instance, the lack of carrier fluid or solvent in HMAs formulations overcomes the dangers involved with the use of solvents and volatile organic compound (VOC) pollutants. It allows for higher processing rates and lower transport/inventory maintenance costs. Hot melt adhesives have no solvents. The HMAs dissolve the polymer using water. This factor is another reason several different solvent-based goods sectors are transitioning to HMAs. For example, In September 2020, SABA announced modern HMAs and launched Sabamelt 4732 for pocket coil unit manufacturing. SABA reaffirms its pioneering role as the solvent-free foam bonding specialist, with more products being released later this year. Due to the increasing demand for environmentally friendly adhesives from consumers. HMAs cause negligible emissions, which have little or no effect on the environment. There is no requirement for extra ventilation, unlike adhesives with solvents, nor are they flammable. The price point is very low as it holds prices down for packaging and manufacturing with high-volume operations. Therefore, the use of HMAs over solvent-based adhesives is supported by regulatory agencies, governments, and environmental organizations. Governments worldwide devise supportive strategies to continue helping adoption, thereby boosting the market growth during the forecast period.
Growing Demand for Polyurethane HMAs from Various End-use Industries to Drive the Hot Melt Adhesives Market
The increasing demand for polyurethane is another driver for the rise in demand for polymer-based HMAs. Polyurethane is a low-volatile organic compound that also makes it popular as it can be used to manufacture HMAs as some raw materials. Polyurethane adhesives are specifically designed to hold together non-porous materials such as metal and wood, making them suitable for bookbinding, shoemaking, and product packaging applications. PUR is ideal for a broad range of woodworking applications, finish carpentry, shoe repair, furniture repair, broken glassware repair, laminate countertops, construction and remodeling, ceramic ceiling tiles, and others due to its higher strength, short set time, and durability. For instance, in February 2020 Jowat announced the introduction of an exceptional product at the world-leading trade fair for the windows industry. Jowatherm-Reaktant MR 604.90 is the first PUR HMAs with a reduced monomer content, with hazard-free marking approved according to RAL-GZ 716 for the wrapping of PVC window profiles. Generally, polyurethane HMAs create a tighter bond than conventional products. This factor is attributed to the tight initial bond formed by the PUR HMAs and then strengthened as the adhesive interacts in the air with moisture. It is a chemical method known as cross-linking in which the PUR HMAs bind to the glued object and form a solid, permanent bond of its own. PUR HMAs absorb moisture from the substrates and the environment and cure it to create a tighter bond than most other adhesives, including adhesives dependent on water and other formulations of HMAs. Since polyurethane are applied like most HMAs, using glue guns or related tools, operators can easily get up to speed on enforcing best practices without having to learn all new techniques and equipment.
Restraints:
Lower thermal resistance of HMA
HMA are highly effective when the temperature is close to their flow point that makes movement and bonding of the adhesives easy for various applications such as packaging and nonwoven hygiene products. However, they exhibit limitations at high temperatures due to lesser thermal resistance. Thus, they are replaced by solvent and waterborne adhesives for such applications.
