Composition of Adhesives

Abstract

Adhesives and sealants are generally developed and prepared for many applications such as packaging, construction, automobile, electronic, etc. An adhesive formulation will depend on the base materials and requirements of a particular application. Development managers or formulators have to have a public knowledge about the chemical composition and role of many components for reducing trials and errors. This chapter focuses on the definition and function of adhesive composition such as primary resins, solvents, fillers, plasticizers, reinforcements, and various additives.

Introduction

An adhesive is a polymer mixture or polymerizable material in a liquid or semiliquid state that adheres substrates together (Petrie 2000). Adhesives may be composed of many components such as polymer, oligomer, filler, and additives from either natural or synthetic sources. It is very important to understand the components for adhesive formulation. The information
