Most adhesives form a bond by filling in the minute pits and fissures normally present even in very smooth surfaces. Adhesive bonds are economical, distribute the stress at the bonding point, resist moisture and corrosion , and eliminate the need for rivets and bolts. The effectiveness of an adhesive depends on several factors, including resistance to slippage and shrinkage, malleability, cohesive strength, and surface tension, which determines how far the adhesive penetrates the tiny depressions in the bonding surfaces.
Adhesives vary with the purpose for which they are intended.
Such purposes now include the increasing use of adhesives in surgery. All Rights Reserved Worldwide.
