SealMaster® Secondary sealing
Secondary seal mounted on the tank edge
SealMaster floating roof sealant was developed over 35 years ago with the aim of creating a seal that adapts to the irregularities of edge spaces, while remaining gas-tight and virtually maintenance-free. The result is the SealMaster sealing system.

Advantages of the programme
- Best available technology to reduce emissions and product losses
SealMaster is designed according to EEMUA 159 guidelines, with standard working range R(-X/+3X), highest BREF rating and best KRA factor according to EPA Chapter 42. - Excellent working area
SealMaster can be designed for both EEMUA R(-X/+3X) and API ± approx. 10 cm working range. - Good weather protection
The seal prevents the penetration of rainwater. - Trouble-free operation
SealMaster centres the floating roof and dampens horizontal movements, preventing the roof from sticking and the edge seal from being pinched between the roof and the tank shell.
Construction details
Abrasion and UV resistant materials
Sliding parts in contact with the tank shell are wear-resistant for long life.
Flexible construction
Adapts well to the deviations of the tank shell and ensures that no gaps occur.
Multiple scraper tips
Flexible design that works with all common tank designs - suitable for butt-welded, lap-welded or riveted storage tanks.
