Adhesives
Adhesives
Adhesives are chemical substances used to bond two or more surfaces together by forming a strong interfacial attachment that resists separation. They function through a combination of mechanical interlocking, chemical bonding, and surface attraction forces, depending on the type of adhesive and substrate involved. Adhesives are available in various forms, including liquid, paste, film, powder, and hot-melt systems, and can be formulated from natural or synthetic polymers such as epoxy, polyurethane, acrylic, silicone, and rubber-based compounds. They are widely used across industries including construction, automotive, packaging, woodworking, footwear, electronics, and aerospace due to their ability to distribute stress evenly, reduce weight compared to mechanical fasteners, and provide improved aesthetics and corrosion resistance.
