HOTMELT Meaning and
Definition
-
Hotmelt refers to a type of adhesive that is designed to be applied in a molten state and solidifies upon cooling. It is also known as hot glue or hot glue stick and is widely used in various industries and applications due to its versatility and advantages.
Hotmelt adhesives are typically made from a base polymer, such as ethylene-vinyl acetate (EVA) or polyamide, mixed with other additives, such as tackifiers and stabilizers. These components are combined and heated until they melt into a liquid form that can be easily dispensed. Common methods of application include hotmelt glue guns, rollers, or nozzles.
One of the key advantages of hotmelt is its fast-setting property, as it solidifies rapidly upon cooling. This quick curing time allows for efficient production processes as it minimizes the need for clamping or other time-consuming methods. Additionally, hotmelt adhesives offer high bond strength, excellent adhesion to various substrates including plastics, wood, and fabrics, and good heat resistance.
Hotmelt finds applications in diverse industries including packaging, woodworking, automotive, textiles, electronics, and crafts. It is commonly used for sealing cartons, bonding components, laminating surfaces, and creating bonds in carpeting, upholstery, and footwear manufacturing.
Overall, hotmelt is a versatile adhesive that provides strong and durable bonds while offering the convenience of rapid curing and versatility across various materials and applications.
Etymology of HOTMELT
The term "hotmelt" is a compound word formed by combining "hot" and "melt".
The word "hot" can be traced back to the Old English word "hāt", which means "having a high temperature or feeling the sensation of heat". It has Germanic origins and is related to the Old High German word "heiz", meaning "hot", and the Old Norse word "heit", which also means "hot".
On the other hand, "melt" comes from the Old English word "meltan", which means "to become liquid or dissolve by heat". It shares its root with the Dutch word "smelten" and the German word "schmelzen", both of which have the same meaning.
When combined, "hotmelt" refers to a substance that becomes liquid or soft when heated to a high temperature.
