Primers for adhesive bonding

Inorganic coatings as primers for adhesive bonding and painting have been investigated for almost two decades. The basic mechanism by which they en-...

A new primer (see Primers for adhesive bonding) has been developed that enables a cyanoacrylate to be used to bond polyolefins. The primer is applied to one surface, adhesive to the other - the bond is virtually instantaneous. This will allow the designers flexibility in choice of plastics, enabling less costly polyolefins to be selected. 

Performance of primers has been studied both in general construction and water-retaining structures.Further information may be found in articles on Selection of joint sealants. Sealant joint design, Paint primers and Primers for adhesive bonding. 

An example of an application is given in Primers for adhesive bonding. 

The more common environmental problem with metal joints is attack by water. In addition to alloy composition, pre-treatment and primer, durability is affected by the adhesive used (see Pre-treatment of metals prior to bonding. Pre-treatment of polymers. Primers for adhesive bonding). Sell has ranked adhesives in the order of durability they provide with aluminium substrates ... 

Almost always the Pre-treatment of metals prior to bonding is essential to the successful use of adhesives. A more general discussion of Primers for adhesive bonding is given elsewhere this article, which complements Silane adhesion promoters, provides detailed discussion of this important class of materials. 

Primers for adhesive bonding chemically functionalize the substrate surface to provide pathways for chemical bonding with a selected silicone cure system. The increase of chemical bond improves adhesion durability. The main disadvantage of priming the substrate is the addition of an extra step in the whole process of adhesive application. The primers are usually Silane adhesion promoters, a reactive alkoxy silane molecule, oligomer, or a mixture of two or more different silanes.
