Adhesion to drum surfaces
Advantages
- Application on site
Disadvantages
- Minimum outside temperatures for application are required
- Poorer adhesion when compared to vulcanisation
- Risk of material deposition and infiltration
Vulcanisation of the drum lining
Advantages
- Excellent adhesion to rubber - metal adhesion > 11 N/mm²
- Application under controlled climate conditions at the factory
- No air pockets
- 100 % sealed edges
Disadvantages
- Application only with the aid of factory based autoclaves
Tegum sand blasts all surfaces of the drum that are to be vulcanised in the autoclaves to ensure the best possible adhesion.
