Bonding Silicone Rubber to Various Substrate

The bonding of silicone rubbers to other materials or to themselves is a very wide field. Most commonly they are classified as  

The intention of this chapter is to outline the advantages of using HTV and LR silicone rubbers. These materials are most commonly used by the silicone rubber industry. It would however be wrong to think that silicone rubbers and their bonding were limited to just these two groups of materials and this chapter will also consider other silicone specialities. 

HTV and liquid silicone rubber LR, are used in moulding at elevated temperatures (press, transfer or injection moulding). 

The reader is encouraged to refer to publications on silicone rubbers used in the applications mentioned above, and to trade literature from the industries and applications [1, 2, 3, 4, 5, 6, 7, 8, 9].

It is also possible to bond silicone rubbers to various substrates which are not injection moulded. Such materials range from steel and aluminium to ceramics, glass or any other solid. 

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.
