Ragasztóanyaggal, commonly referred to as adhesive, is a substance used to bond materials together. Adhesives work through a variety of mechanisms, including mechanical interlocking, surface wetting, and chemical bonding. The choice of adhesive depends on the materials being joined, the required bond strength, and the environmental conditions the bond will be exposed to.

Adhesives can be broadly categorized into two main types: natural and synthetic. Natural adhesives are derived from organic sources such as plant starches, animal proteins, or natural resins. Examples include glue made from animal hides or paste made from flour and water. Synthetic adhesives, on the other hand, are manufactured from petrochemicals or other synthetic polymers. This category includes a vast array of products like epoxies, cyanoacrylates (super glue), silicones, and various types of tapes.

The application of adhesives ranges from everyday household repairs and crafts to highly specialized industrial processes. In construction, adhesives are used for bonding tiles, wood, and even structural components. In electronics, they are crucial for assembling circuit boards and encapsulating components. The automotive and aerospace industries rely heavily on adhesives for weight reduction and to join dissimilar materials.

The effectiveness of an adhesive is determined by factors such as its viscosity, curing time, tensile strength, shear strength, and resistance to temperature, moisture, and chemicals. Proper surface preparation of the materials to be bonded is essential for achieving a strong and durable joint. This often involves cleaning, abrading, or priming the surfaces.
