Flange Sealant
Silicones – MS polymers – Anaerobic sealants – Permanently plastic sealants – Solvent-based sealants
Flange sealants prevent gases or liquids from escaping between two joining partners (ex. flange surfaces). The sealants selected, depending on the requirements and application, form an impermeable barrier.
DREI BOND flange sealants reliably seal the component surfaces with maximum surface contact and achieve sustainable corrosion protection on the wetted sealing surfaces. The main task of the sealants in this application is to balance or compensate for deformations, while the transfer of forces is not in the foreground.
Special products are available for individual requirements in terms of curing times, flexibility and strength of the connection as well as temperature resistance or necessary resistance to external influences such as gases, acids or oils.
Depending on the application, the following are suitable:
F.A.Q.
In which areas are flange sealants used?
Flange sealants are primarily used in automotive and mechanical engineering. Among other things, they are used to seal engine flanges, pumps, gearboxes and differentials. The products are equally suitable for sealing surfaces and connections between two flanges. These liquid and curing sealants reliably prevent the escape of gases and liquids and precisely compensate for tolerances. In industrial applications, they often represent a powerful and easy-to-use alternative to solid seals.
In view of the challenging areas of application such as in engines and transmissions, flange sealants must be durable in a variety of ways. This includes resistance to extreme temperatures, to various media such as oils and coolants and to vibrations. When buying the optimal flange sealant, pay attention to the information on the gap filling capacity.
