Advantages And Disadvantages Of Adhesive

Chapter 1

INTRODUCTION

An adhesive is any substance applied to the surfaces of materials that binds them together and resists separation. The term "adhesive" may be used interchangeably with glue, cement, mucilage, or paste. Adjectives may be used in conjunction with the word "adhesive" to describe properties based on the substance's physical or chemical form, the type of materials joined, or conditions under which it is applied.[1]

The use of adhesives offers many advantages over binding techniques such as sewing, mechanical fastening, thermal bonding etc. Adhesive offers the ability to bind different materials together. Advantages using adhesive are distribution of stress more efficiently across the joint, the cost effectiveness, easily mechanized process, an ...

[5] Do not produce any mechanical aggression to the substrate, avoiding any damage to the structure of the material. [5] Great flexibility in the product design as well as an improvement in its aesthetics. [6]

1.4 Disadvantages Requirement of better Surface treatment. [1] More Curing time require adhesives.[2] Adhesion is difficult to control. [2] Restricted structural behavior at high temperature. [7]
