An adhesive is generally characterized as a material capable of bonding separate articles together by adhering to the surfaces of both articles. The selection of an adhesive bonding agent for a particular use is governed by the chemical and physical properties of the adhesive bonding agent composition and the chemical and physical properties of the surfaces of the articles to be bonded. Some of the chemical and physical properties to be considered when an adhesive binding agent is selected are:
1. The affinity of the surfaces to be bonded to the adhesive bonding agent.
2. The ability to the adhesive bonding agent to adequately wet surface to be bonded.
3. The ability of the adhesive bonding agent to be placed in intimate contact with the surface to be bonded.
4. The cohesive strength of the adhesive bonding agent itself.
5. The chemical reactivity of the adhesive agent with the surface to be bonded.
Melt adhesives are bonding agents which achieve a solid state and resultant strength by cooling as contrasted with other adhesives which achieve the solid state through evaporation or removal of solvents. Prior heating, a hot-melt adhesive may be a thermoplastic, one hundred pc solid material, and all adhesive. Application of warmth brings the material to the liquid state, and after removal of the warmth, it sets by simple cooling. Hot Melt Adhesives be defined as adhesives that melt and flow on application of heat and solidifies on cooling to offer a strong adhesion. Hot melt adhesives are solvent-free, solvent-free, solid compounds that have negligible or no VOC (volatile organic compound) compared to solvent-based adhesives.
The global market for hot melt adhesives is gaining significant impetus from the rise in the trading activities, leading to a high demand for packaging. The increasing construction activities across the world is also fueling the need for hot melt adhesives substantially. On the other hand, the volatility in crude oil prices and the easy availability of substitutes are likely to create hindrances in the higher adoption of hot melt adhesives across the world in the years to come. The global Hot Melt Adhesives (HMA) market size exceeded USD 6.60 billion, globally in 2018 and is estimated to grow at over 6.4% CAGR between 2019 and 2022, projected to reach USD 9.46 billion by 2022, in terms of value. The HMA market is driven by the increasing demand for HMA from applications such as packaging solutions, nonwoven hygiene products, and consumer DIY.
Hot melt adhesives are formulations supported thermoplastic polymers which may be softened and reshaped on heating above their freezing point. These adhesives are applied on a cloth in liquid state and offer easy to wash application with minimum toxicity. They’re served during a big selection of industries such as packaging because of their high stability & strength, making them an appropriate alternative to solvent-borne adhesives.
Increasing product innovations in hygiene solutions to reduce waste, provide comfort & improve absorption has enabled the event of unique adhesives to manufacture disposable hygiene products will drive the growth of hot melt adhesives market. Hot melt adhesives demand is attributed towards rising importance regarding disposable hygiene products and growing government initiatives to market health & wellness among individuals. With increasing awareness for private hygiene, consumers are trying to find products with enhanced features such as better absorption and improved softness which has augmented the adoption of environment friendly disposable adhesives.
