Zircoaluminate adhesion promoters constitute a novel class of compounds which have proven themselves useful in arresting corrosion on coated metals, enhancing adhesion of adhesives to rubber and metal, and improving bonding of formed rubber articles containing ZA to other substrates. 

Rubber range - vulcanised butyl rubber, CP, EPDM, CSM, NR, NBR and SBR rubbers. Substrate range - using Chemosil 211 primer, the PV bonding agents will bond ferrous and non-ferrous metals and plastics. They can be used as one-coat systems to bond vulcanised rubbers to themselves or to other vulcanised rubbers. 

Laminating. Nitrile rubbers blended with various epoxy resins and activated by suitable amines and/or acidic agents have been employed to bond elastomers, plastics, fabrics, wood, and metals to themselves and each other. Normally good bond strength can be developed at or near room temperature. Any information must be adapted to the substrate being bonded but Table 26 gives a starting formulation. The triethylenetetramine is added as a 50% solution in methyl ethyl ketone just prior to use. Such a cement will cure in 4-24 hours at room temperature and less than 30 minutes at 150°F. 

Adhesives are used to bond various different substrates such as metal, glass, wood, or plastic among many others (Houwink 1967). The appropriate adhesive and its chemistry have to be chosen in dependence of the application and the substrate which is bonded. A wide range of different chemistries are used to formulate adhesives. The chemical nature of the adhesive defines its field of application. Most adhesives which are used in the industry today are using epoxy-, polyurethane-, acrylic-, and silicone- or rubber chemistry.
