Multicomponent Bonding Adhesives

3 Multicomponent Bonding Adhesives 3.3.1 Albumin/Glutaraldehyde Adhesive

A special case of specific adhesion is when there are primary chemical bonds present. For example, graft or block copolymers may bond the different phases of a multicomponent material together see Chapter 13. Direct bonding to substrates is also encouraged in many systems. For example, maleic anhydride comonomers are used to bond to metallic surfaces. 

The increase of adhesion owing to the RS interfacial layer is reflected in the macroscopic properties of various multicomponent systems [3, 4, 10]. Direct verification of the chemical bonds between RS molecules and the neighbouring phases were carried out using X-ray photoelectron spectroscopy and DSC methods. These results have been published elsewhere [11]. 

For a large-scale bonding operation, hand mixing is costly, messy, and slow, and repeatability is entirely dependent on the operator. Equipment is available that can meter, mix, and dispense multicomponent adhesives on a continuous or shot basis.
