🟩 TYPES OF ADHESIVES | APPLICATIONS OF ADHESIVES | USES
Overview
Adhesives are substances capable of holding materials together through surface bonding. They exist in numerous chemical structures—natural, synthetic, waterborne, solvent-based, hotmelt, reactive, and polymer-modified systems—each designed for specific substrates and performance requirements. Modern industries rely heavily on advanced adhesive technologies for construction, woodworking, automotive, packaging, textiles, electronics, and general-purpose bonding.
