HTV Used in Other Bonding Applications

Using primers or undercuts the field of applications for HTV is increased dramatically. The primers can be applied to normal solid substrates as well as to fabrics and single fibres. 

Depending on the scale of production, HTV can be used for all applications as described in Section 11.4. The only limitation is the speed of curing and the respective moulding temperatures. In all cases HTV cures slower and at higher temperatures than LR. In most cases this moulding temperature and curing time is responsible for the fact that it is hard to combine plastics with HTV. Most typically, metals, steel, iron, etc., will be the substrates. 

A very popular technique using HTV is the combination of moulded silicone parts together with extruded HTV profiles, tubing or mouldings. Examples of such composites are catheters used as medical devices, electrical cables, long rod insulators and composite insulators.
